Thus, use of fossil fuel is efficient which results in large liberation of carbon dioxide in atmosphere. Tons of this CO2 raises the risk of dangerous climate changes. To minimize the risk carbon capture and storage (CCS) has to be used so that the emitted carbon dioxide do not reach the atmosphere. CCS is being considered as one of the options that could have a major role to play in India.With the growing awareness towards the global warming, carbon capture and sequestration has a great importance. New technologies and theories are in use to capture CO2. This paper contains the methodology and technologies that is in use to capture carbon dioxide in India. The present scenario of CCS is also being discussed. CCS is playing a major role in enhancing recovery of oil (ERO). Both the purpose 1) minimizing percentage of carbon dioxide in atmosphere and 2) enhancing recovery of oil are fulfilled from the CCS. The CO2 is usually captured from coal based power plant and from some industrial sources and then stored in the geological formations like oil and gas reservoir and deep aquifers or in oceans. India has large reservoirs of coal which are being used for storing CO2, as coal is a good absorbent of CO2. New technologies and studies are going on for injection purposes. Government has initiated new plans for CCS as CCS is technically feasible and economically attractive. A discussion is done on new schemes that should bring up CCS plans and approaches. Stakeholders are welcomed for suitability of CCS. There is still a need to potentially capture the CO2 and avail its storage in developing country like India. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carbon%20Capture%20and%20Storage%20%28CCS%29" title="Carbon Capture and Storage (CCS)">Carbon Capture and Storage (CCS)</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20%28CO2%29" title=" carbon dioxide (CO2)"> carbon dioxide (CO2)</a>, <a href="https://publications.waset.org/abstracts/search?q=enhance%20oil%20recovery" title=" enhance oil recovery"> enhance oil recovery</a>, <a href="https://publications.waset.org/abstracts/search?q=geological%20formations" title=" geological formations"> geological formations</a>, <a href="https://publications.waset.org/abstracts/search?q=stakeholders" title=" stakeholders "> stakeholders </a> </p> <a href="https://publications.waset.org/abstracts/17427/carbon-capture-and-storage-prospects-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17427.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">470</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5966</span> Carbon Dioxide Capture, Utilization, and Storage: Sequestration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ankur%20Sachan">Ankur Sachan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon dioxide being the most anthropogenic greenhouse gas,it needs to be isolated from entering into atmosphere. Carbon capture and storage is process that captures CO2 emitted from various sources, separates it from other gases and stores it in a safe place preferably in underground geological formations for large period of time. It is then purified and monitored so that can be made to reuse. Monoethanolamine, zeolitic imidazolate framework, microalgae, membranes etc are utilized to capture CO2. Post-combustion, pre-combustion and oxyfuel combustion along with chemical looping combustion are technologies for scrubbing CO2. The properties of CO2 being easily miscible and readily dissolving in oil with impurities makes it capable for numerous applications such as in producing oil by enhanced oil recovery (EOR), Bio CCS Algal Synthesis etc. CO2-EOR operation is capable to produce million barrels of oil and extend the field's lifetime as in case of Weyburn Oil Field in Canada. The physical storage of CO2 is technically the most feasible direction provided that the associated safety and sustainability issues can be met and new materials for CCUS process at low cost are urgently found so that so that fossil based systems with carbon capture are cost competitive. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture" title="carbon capture">carbon capture</a>, <a href="https://publications.waset.org/abstracts/search?q=CCUS" title=" CCUS"> CCUS</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=oil" title=" oil "> oil </a> </p> <a href="https://publications.waset.org/abstracts/20310/carbon-dioxide-capture-utilization-and-storage-sequestration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20310.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">519</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5965</span> A Comprehensive Study on CO₂ Capture and Storage: Advances in Technology and Environmental Impact Mitigation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oussama%20Fertaq">Oussama Fertaq</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper investigates the latest advancements in CO₂ capture and storage (CCS) technologies, which are vital for addressing the growing challenge of climate change.

CO₂ injection into the oceans and geological formation as a process of physical carbon capture are two of the most promising emerging strategies for mitigating climate change and global warming. The purpose of this research is to evaluate the two mentioned methods of CO₂ sequestration and to assess information on previous and current advancements, limitations, and uncertainties associated with carbon sequestration in order to identify possible prospects for ensuring the timely implementation of the technology, such as determining how governments and companies can gain a better understanding of CO₂ storage in terms of which media have the most applicable capacity, which type of injection has the fewer environmental impact, and how much carbon sequestration and storage will cost. The behavior of several forms is characterized as a near field, a far field, and a see-floor in ocean storage, and three medias in geological formations as an oil and gas reservoir, a saline aquifer, and a coal bed. To determine the capacity of various forms of media, an analysis of some models and practical experiments are necessary. Additionally, as a major component of sequestration, the various injection methods into diverse media and their monitoring are associated with a variety of environmental impacts and financial consequences. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20sequestration" title="carbon sequestration">carbon sequestration</a>, <a href="https://publications.waset.org/abstracts/search?q=ocean%20storage" title=" ocean storage"> ocean storage</a>, <a href="https://publications.waset.org/abstracts/search?q=geologic%20storage" title=" geologic storage"> geologic storage</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20transportation" title=" carbon transportation"> carbon transportation</a> </p> <a href="https://publications.waset.org/abstracts/161056/critical-review-of-oceanic-and-geological-storage-of-carbon-sequestration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161056.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">102</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5962</span> Retrofitting Cement Plants with Oxyfuel Technology for Carbon Capture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Peloriadi%20Konstantina">Peloriadi Konstantina</a>, <a href="https://publications.waset.org/abstracts/search?q=Fakis%20Dimitris"> Fakis Dimitris</a>, <a href="https://publications.waset.org/abstracts/search?q=Grammelis%20Panagiotis"> Grammelis Panagiotis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Methods for carbon capture and storage (CCS) can play a key role in the reduction of industrial CO₂ emissions, especially in the cement industry, which accounts for 7% of global emissions. Cement industries around the world have committed to address this problem by reaching carbon neutrality by the year 2050. The aim of the work to be presented was to contribute to the decarbonization strategy by integrating the 1st generation oxyfuel technology in cement production plants. This technology has been shown to improve fuel efficiency while providing one of the most cost-effective solutions when compared to other capture methods. A validated simulation of the cement plant was thus used as a basis to develop an oxyfuel retrofitted cement process. The process model for the oxyfuel technology is developed on the ASPEN (Advanced System for Process Engineering) PLUSTM simulation software. This process consists of an Air Separation Unit (ASU), an oxyfuel cement plant with coal and alternative solid fuel (ASF) as feedstock, and a carbon dioxide processing unit (CPU). A detailed description and analysis of the CPU will be presented, including the findings of a literature review and simulation results, regarding the effects of flue gas impurities during operation.

This research targets to continuously capture the low concentration CO₂ from the tail gas of the regenerative thermal oxidizer (RTO) in the high technology industry. A rotating packed bed (RPB) reactor is investigated to capture the efficiency of CO₂ using a mixture of NaOH/Na₂CO₃ solutions to simulate the real absorbed solution. On a lab scale, semi-batch experiments of continuous gas flow and circulating absorbent solution are conducted to find the optimal parameters and are then examined in a continuous operation. In the semi-batch tests, the carbon capture efficiency and pH variation in the conditions of a low concentration CO₂ (about 1.13 vol%), the NaOH concentration of 1 wt% or 2 wt% mixed with 14 wt% Na₂CO₃, the rotating speed (600, 900, 1200 rpm), the gas-liquid ratio (100, 200, and 400), and the temperature of absorbent solution of 40 ºC are studied. The CO₂ capture efficiency significantly increases with higher rotating speed and smaller gas-liquid ratio, respectively, while the difference between the NaOH concentration of 1 wt% and 2 wt% is relatively small. The maximum capture efficiency is close to 80% in the conditions of the NaOH concentration of 1 wt%, the G/L ratio of 100, and the rotating speed of 1200 rpm within the first 5 minutes. Furthermore, the continuous operation based on similar conditions also demonstrates the steady efficiency of the carbon capture of around 80%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20capture" title="carbon dioxide capture">carbon dioxide capture</a>, <a href="https://publications.waset.org/abstracts/search?q=regenerative%20thermal%20oxidizer" title=" regenerative thermal oxidizer"> regenerative thermal oxidizer</a>, <a href="https://publications.waset.org/abstracts/search?q=rotating%20packed%20bed" title=" rotating packed bed"> rotating packed bed</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20hydroxide" title=" sodium hydroxide"> sodium hydroxide</a> </p> <a href="https://publications.waset.org/abstracts/182235/an-experimental-study-of-low-concentration-co2-capture-from-regenerative-thermal-oxidation-tail-gas-in-rotating-packed-bed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182235.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">60</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5960</span> Carbon Capture: Growth and Development of Membranes in Gas Sequestration</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sreevalli%20Bokka">Sreevalli Bokka</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Various technologies are emerging to capture or reduce carbon intensity from a gas stream, such as industrial effluent air and atmosphere.

Pennsylvania Geological Survey participated in the MRCSP Phase I research to characterize potential storage formations in Pennsylvania. The MRCSP’s volumetric method estimated ~89 gigatonnes (Gt) of total CO2 storage resources in deep saline formations, depleted oil and gas reservoirs, coals, and shales in Pennsylvania. Meanwhile, the US-DOE calculated storage efficiency factors using log-odds normal distribution and Monte Carlo sampling, revealing contingent storage resources of ~18 Gt to ~20 Gt in deep saline formations, depleted oil and gas reservoirs, and coals in Pennsylvania. Additionally, the USGS employed Beta-PERT distribution and Monte Carlo sampling to determine buoyant and residual storage efficiency factors, resulting in 20 Gt of contingent storage resources across four storage assessment units in Appalachian Basin. However, few studies have explored CO2 storage resources in shales in the region, yielding inconclusive findings. This article provides a critical and most up to date review and analysis of geological CO2 storage resources in Pennsylvania and the region. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture%20and%20storage" title="carbon capture and storage">carbon capture and storage</a>, <a href="https://publications.waset.org/abstracts/search?q=geological%20CO2%20storage" title=" geological CO2 storage"> geological CO2 storage</a>, <a href="https://publications.waset.org/abstracts/search?q=pennsylvania" title=" pennsylvania"> pennsylvania</a>, <a href="https://publications.waset.org/abstracts/search?q=appalachian%20basin" title=" appalachian basin"> appalachian basin</a> </p> <a href="https://publications.waset.org/abstracts/185433/a-critical-review-of-assessments-of-geological-co2-storage-resources-in-pennsylvania-and-the-surrounding-region" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185433.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">52</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5958</span> Numerical Investigation of Oxy-Fuel Combustion in Gasoline Engine for Carbon Capture and Storage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhijun%20Peng">Zhijun Peng</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiang%20Li"> Xiang Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Dayou%20Li"> Dayou Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Raouf%20Mobasheri"> Raouf Mobasheri</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdel%20Aitouche"> Abdel Aitouche</a> </p> <p class="card-text"><strong>Abstract:</strong></p> To implement carbon capture and storage (CCS) for eliminating carbon dioxide (CO₂) emissions, this paper describes a study on oxy-fuel combustion (OFC) with an ethanol-gasoline dual-fuel spark ignition (DFSI) engine under economical oxygen consumption at low and mid-high loads which was performed by 1D simulation. It is demonstrated that under OFC mode without other optimisation, brake mean effective pressure (BMEP) can meet the requirement at mid-high load, but it has a considerable decline at low load compared to conventional air combustion (CAC) mode. Moreover, there is a considerable deterioration in brake specific fuel consumption (BSFC) compared to that of CAC mode. A practical method is proposed to optimise the DFSI engine performance under OFC mode by changing intake charge components and utilising appropriate water injection (WI) strategies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=oxy-fuel%20combustion" title="oxy-fuel combustion">oxy-fuel combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=dual-fuel%20spark%20ignition%20engine" title=" dual-fuel spark ignition engine"> dual-fuel spark ignition engine</a>, <a href="https://publications.waset.org/abstracts/search?q=ethanol" title=" ethanol"> ethanol</a>, <a href="https://publications.waset.org/abstracts/search?q=gasoline" title=" gasoline"> gasoline</a>, <a href="https://publications.waset.org/abstracts/search?q=computer%20simulation" title=" computer simulation"> computer simulation</a> </p> <a href="https://publications.waset.org/abstracts/150775/numerical-investigation-of-oxy-fuel-combustion-in-gasoline-engine-for-carbon-capture-and-storage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150775.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">91</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5957</span> Kinetics of Growth Rate of Microalga: The Effect of Carbon Dioxide Concentration </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Retno%20Ambarwati%20Sigit%20Lestari">Retno Ambarwati Sigit Lestari</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Microalga is one of the organisms that can be considered ideal and potential for raw material of bioenergy production, because the content of lipids in microalga is relatively high. Microalga is an aquatic organism that produces complex organic compounds from inorganic molecules using carbon dioxide as a carbon source, and sunlight for energy supply. Microalga-CO₂ fixation has potential advantages over other carbon captures and storage approaches, such as wide distribution, high photosynthetic rate, good environmental adaptability, and ease of operation. The rates of growth and CO₂ capture of microalga are influenced by CO₂ concentration and light intensity. This study quantitatively investigates the effects of CO₂ concentration on the rates of growth and CO₂ capture of a type of microalga, cultivated in bioreactors. The works include laboratory experiments as well as mathematical modelling. The mathematical models were solved numerically and the accuracy of the model was tested by the experimental data. It turned out that the mathematical model proposed can well quantitatively describe the growth and CO₂ capture of microalga, in which the effects of CO₂ concentration can be observed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Microalga" title="Microalga">Microalga</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20concentration" title=" CO2 concentration"> CO2 concentration</a>, <a href="https://publications.waset.org/abstracts/search?q=photobioreactor" title=" photobioreactor"> photobioreactor</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20model" title=" mathematical model "> mathematical model </a> </p> <a href="https://publications.waset.org/abstracts/106192/kinetics-of-growth-rate-of-microalga-the-effect-of-carbon-dioxide-concentration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/106192.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">125</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5956</span> High-Pressure CO₂ Adsorption Capacity of Selected Unusual Porous Materials and Rocks</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Rimnacova">Daniela Rimnacova</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryna%20Vorokhta"> Maryna Vorokhta</a>, <a href="https://publications.waset.org/abstracts/search?q=Martina%20Svabova"> Martina Svabova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CO₂ adsorption capacity of several materials - waste (power fly ash, slag, carbonized sewage sludge), rocks (Czech Silurian shale, black coal), and carbon (synthesized carbon, activated carbon as a reference material) - were measured on dry samples using a unique hand-made manometric sorption apparatus at a temperature of 45 °C and pressures of up to 7 MPa. The main aim was finding utilization of the waste materials and rocks for removal of the air or water pollutants caused by anthropogenic activities, as well as for the carbon dioxide storage. The equilibrium amount of the adsorbate depends on temperature, gas saturation pressure, porosity, surface area and volume of pores, and last but not least, on the composition of the adsorbents. Given experimental conditions can simulate in-situ situations in the rock bed and can be achieved just by a high-pressure apparatus. The CO₂ excess adsorption capacities ranged from 0.018 mmol/g (ash) to 13.55 mmol/g (synthesized carbon). The synthetized carbon had the highest adsorption capacity among all studied materials as well as the highest price. This material is usually used for the adsorption of specific pollutants. The excess adsorption capacity of activated carbon was 9.19 mmol/g. It is used for water and air cleaning. Ash can be used for chemisorption onto ash particle surfaces or capture of special pollutants. Shale is a potential material for enhanced gas recovery or CO₂ sequestration in-situ. Slag is a potential material for capture of gases with a possibility of the underground gas storage after the adsorption process. The carbonized sewage sludge is quite a good adsorbent for the removal and capture of pollutants, as well as shales or black coal which show an interesting relationship between the price and adsorption capacity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82" title=" CO₂"> CO₂</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20pressure" title=" high pressure"> high pressure</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20materials" title=" porous materials"> porous materials</a> </p> <a href="https://publications.waset.org/abstracts/98052/high-pressure-co2-adsorption-capacity-of-selected-unusual-porous-materials-and-rocks" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98052.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5955</span> Experimental Study of CO₂ Hydrate Formation in Presence of Different Promotors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samaneh%20Soroush">Samaneh Soroush</a>, <a href="https://publications.waset.org/abstracts/search?q=Tommy%20Golczynski"> Tommy Golczynski</a>, <a href="https://publications.waset.org/abstracts/search?q=Tony%20Spratt"> Tony Spratt</a> </p> <p class="card-text"><strong>Abstract:</strong></p> One of the new technologies for CO₂ capture, storage, and utilization (CCSU) is forming clathrate hydrate. This technology has some unknowns and challenges that make it difficult to apply in the real world. The low formation rate is one of the main difficulties of CO₂ hydrate. In this work, the effect of different promotors on the hydrate formation rate has been studied. Two surfactants, sodium dodecyl sulfate (SDS), tetra-n-butylammonium bromide (TBAB), and cyclopentane (CP) as a thermodynamic promotor and their combination have been used for the experiments. The results showed that the SDS is a powerful kinetic promotor and its combination with CP helps to convert more CO₂ to hydrate in a short time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture" title="carbon capture">carbon capture</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide" title=" carbon dioxide"> carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrate" title=" hydrate"> hydrate</a>, <a href="https://publications.waset.org/abstracts/search?q=promotor" title=" promotor"> promotor</a> </p> <a href="https://publications.waset.org/abstracts/139412/experimental-study-of-co2-hydrate-formation-in-presence-of-different-promotors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139412.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">255</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5954</span> Estimation of Energy Efficiency of Blue Hydrogen Production Onboard of Ships</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Li%20Chin%20Law">Li Chin Law</a>, <a href="https://publications.waset.org/abstracts/search?q=Epaminondas%20Mastorakos"> Epaminondas Mastorakos</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohd%20Roslee%20Othman"> Mohd Roslee Othman</a>, <a href="https://publications.waset.org/abstracts/search?q=Antonis%20Trakakis"> Antonis Trakakis</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The paper introduces an alternative concept of carbon capture for shipping by using pre-combustion carbon capture technology (Pre-CCS), which was proven to be less energy intensive than post-combustion carbon capture from the engine exhaust. Energy assessment on amine-based post-combustion CCS on LNG-fuelled ships showed that the energy efficiency of CCS ships reduced from 48% to 36.6%. Then, an energy assessment was carried out to compare the power and heat requirements of the most used hydrogen production methods and carbon capture technologies. Steam methane reformer (SMR) was found to be 20% more energy efficient and achieved a higher methane conversion than auto thermal reaction and methane decomposition. Next, pressure swing adsorber (PSA) has shown a lower energy requirement than membrane separation, cryogenic separation, and amine absorption in pre-combustion carbon capture. Hence, an integrated system combining SMR and PSA (SMR-PSA) with waste heat integration (WHR) was proposed. This optimized SMR-based integrated system has achieved 65% of CO₂ reduction with less than 7-percentage point of energy penalty (41.7% of energy efficiency). Further integration of post-combustion CCS with the SMR-PSA integrated system improved carbon capture rate to 86.3% with 9-percentage points of energy penalty (39% energy efficiency). The proposed system was shown to be able to meet the carbon reduction targets set by International Maritime Organization (IMO) with certain energy penalties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=shipping" title="shipping">shipping</a>, <a href="https://publications.waset.org/abstracts/search?q=decarbonisation" title=" decarbonisation"> decarbonisation</a>, <a href="https://publications.waset.org/abstracts/search?q=alternative%20fuels" title=" alternative fuels"> alternative fuels</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20carbon" title=" low carbon"> low carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen" title=" hydrogen"> hydrogen</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture" title=" carbon capture"> carbon capture</a> </p> <a href="https://publications.waset.org/abstracts/162788/estimation-of-energy-efficiency-of-blue-hydrogen-production-onboard-of-ships" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162788.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">78</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5953</span> Acidity and Aridity: Soil Carbon Storage and Myeloablation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tom%20Spears">Tom Spears</a>, <a href="https://publications.waset.org/abstracts/search?q=Zotique%20Laframboise"> Zotique Laframboise</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Soil inorganic carbon is the most common form of carbon in arid and semiarid regions, and has a very long turnover time.

However, commercially activated carbons generally require complicated processes and high production costs. Therefore, in this study, an activated carbon originating from green coke waste, that is economically affordable will be used as a carbon source. To synthesize activated carbon, KOH as an activator was employed with variation of C:KOH in ratio of 1:2, 1:3, 1:4, and 1:5, respectively, with an activation temperature of 700°C. The characterizations of activated carbon are obtained from Scanning Electron Microscopy, Energy Dispersive X-Ray, Raman Spectroscopy, and Brunauer-Emmett-Teller. The optimal activated carbon sample with specific surface area of 2,024 m²/g with high carbon content ( > 80%) supported by the high porosity carbon image obtained by SEM was prepared at C:KOH ratio of 1:4. The result shows that the synthesized activated carbon would be an ideal choice for energy storage device applications. Therefore, this study is expected to reduce the costs of activated carbon production by expanding the utilization of petroleum waste. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=activated%20carbon" title="activated carbon">activated carbon</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20storage%20material" title=" energy storage material"> energy storage material</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20coke" title=" green coke"> green coke</a>, <a href="https://publications.waset.org/abstracts/search?q=specific%20surface%20area" title=" specific surface area"> specific surface area</a> </p> <a href="https://publications.waset.org/abstracts/126533/synthesis-and-characterization-of-green-coke-derived-activated-carbon-by-koh-activation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126533.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">167</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5950</span> A Fully Coupled Thermo-Hydraulic Mechanical Elastoplastic Damage Constitutive Model for Porous Fractured Medium during CO₂ Injection</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nikolaos%20Reppas">Nikolaos Reppas</a>, <a href="https://publications.waset.org/abstracts/search?q=Yilin%20Gui"> Yilin Gui</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A dual-porosity finite element-code will be presented for the stability analysis of the wellbore during CO₂ injection.

Methane production in sequestration process and reducing atmospheric carbon dioxide, a main source of greenhouse gas, has been accentuated recently. One focus is capture, separation, and sequestration of industrial carbon dioxide. As a hydrate former, carbon dioxide forms hydrates at moderate temperatures and pressures. This phenomenon could be utilized to capture and separate carbon dioxide from flue gases, and also has the potential to sequester carbon dioxide in the deep seabeds. This research investigated the effect of synthetic surfactants on carbon dioxide hydrate formation, catalysis and consequently, methane production from hydrate permafrosts in sediments. It investigated the sequestration potential of carbon dioxide hydrates in ocean sediments. Also, the catalytic effect of biosurfactants in these processes was investigated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide" title="carbon dioxide">carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrate" title=" hydrate"> hydrate</a>, <a href="https://publications.waset.org/abstracts/search?q=sequestration" title=" sequestration"> sequestration</a>, <a href="https://publications.waset.org/abstracts/search?q=surfactant" title=" surfactant"> surfactant</a> </p> <a href="https://publications.waset.org/abstracts/24778/investigation-of-the-catalytic-role-of-surfactants-on-carbon-dioxide-hydrate-formation-in-sediments" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24778.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">437</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5948</span> Analysis of CO₂ Capture Products from Carbon Capture and Utilization Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bongjae%20Lee">Bongjae Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Beom%20Goo%20Hwang"> Beom Goo Hwang</a>, <a href="https://publications.waset.org/abstracts/search?q=Hye%20Mi%20Park"> Hye Mi Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> CO₂ capture products manufactured through Carbon Capture and Utilization (CCU) Plant that collect CO₂ directly from power plants require accurate measurements of the amount of CO₂ captured. For this purpose, two tests were carried out on the weight loss test. And one was analyzed using a carbon dioxide quantification device. First, the ignition loss analysis was performed by measuring the weight of the sample at 550°C after the first conversation and then confirming the loss when ignited at 950°C. Second, in the thermogravimetric analysis, the sample was divided into two sections of 40 to 500°C and 500 to 800°C to confirm the reduction. The results of thermal weight loss analysis and thermogravimetric analysis were confirmed to be almost similar. However, the temperature of the ignition loss analysis method was 950°C, which was 150°C higher than that of the thermogravimetric method at a temperature of 800°C, so that the difference in the amount of weight loss was 3 to 4% higher by the heat loss analysis method. In addition, the tendency that the CO₂ content increases as the reaction time become longer is similarly confirmed. Third, the results of the wet titration method through the carbon dioxide quantification device were found to be significantly lower than the weight loss method. Therefore, based on the results obtained through the above three analysis methods, we will establish a method to analyze the accurate amount of CO₂.

So CO₂ capture & sequestration has become an effective way to reduce the concentration of CO₂ in the environment. One such way to capture CO₂ in porous materials is by adsorption process. A potential material in this aspect is porous hexagonal boron nitride or 'white graphene' which is a well-known two-dimensional layered material with very high thermal stability. It had been investigated that the sample with hierarchical pore structure and high specific surface area shows excellent performance in capturing carbon dioxide gas and thereby mitigating the problem of environmental pollution to the certain extent. Besides, the presence of sulfur as well as nitrogen in the sample synergistically helps in the increase in adsorption capacity. In this work, a cost effective single step synthesis of highly porous boron nitride nanosheets doped with sulfur had been demonstrated. Besides, the CO₂ adsorption-desorption studies were carried on using a pressure reduction technique. The studies show that the nanosheets exhibit excellent cyclic stability in storage performance. Thermodynamic studies suggest that the adsorption takes place mainly through physisorption. The studies show that the nanosheets exhibit excellent cyclic stability in storage performance. Further, the surface modification of the highly porous nano sheets carried out by incorporating ionic liquids had further enhanced the capturing capability of CO₂ gas in the nanocomposite, revealing that this particular material has the potential to be an excellent adsorbent of carbon dioxide gas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO%E2%82%82%20capture" title="CO₂ capture">CO₂ capture</a>, <a href="https://publications.waset.org/abstracts/search?q=hexagonal%20boron%20nitride%20nanosheets" title=" hexagonal boron nitride nanosheets"> hexagonal boron nitride nanosheets</a>, <a href="https://publications.waset.org/abstracts/search?q=porous%20network" title=" porous network"> porous network</a>, <a href="https://publications.waset.org/abstracts/search?q=sulfur%20doping" title=" sulfur doping"> sulfur doping</a> </p> <a href="https://publications.waset.org/abstracts/77259/sulfur-doped-hierarchically-porous-boron-nitride-nanosheets-as-an-efficient-carbon-dioxide-adsorbent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77259.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">242</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5946</span> Energy-Efficient Storage of Methane Using Biosurfactant in the Form of Clathrate Hydrate</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Farhadian">Abdolreza Farhadian</a>, <a href="https://publications.waset.org/abstracts/search?q=Anh%20Phan"> Anh Phan</a>, <a href="https://publications.waset.org/abstracts/search?q=Zahra%20Taheri%20Rizi"> Zahra Taheri Rizi</a>, <a href="https://publications.waset.org/abstracts/search?q=Elaheh%20Sadeh"> Elaheh Sadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The utilization of solidified gas technology based on hydrates exhibits considerable promise for carbon capture, storage, and natural gas transportation applications. The pivotal factor impeding the industrial implementation of hydrates lies in the need for efficient and non-foaming promoters. In this study, a biosurfactant with sulfonate, amide, and carboxyl groups (BS) was synthesized as a methane hydrate formation promoter, replicating the chemical characteristics of amino acids and sodium dodecyl sulfate (SDS). The synthesis of BS was achieved using an eco-friendly and three-step process. The first two steps were solvent-free, while a water-isopropanol mixture was utilized in the final step. High-pressure autoclave experiments demonstrated a significant enhancement in methane hydrate formation kinetics with low BS concentrations. 50 ppm of BS yielded a maximum water-to-hydrate conversion of 66.9%, equivalent to a storage capacity of 119.9 v/v in distilled water. With increasing BS concentration to 500 ppm, the conversion degree and storage capacity reached 97% and 162.6 v/v, respectively. Molecular dynamic simulation revealed that BS molecules acted as collectors for methane molecules, augmenting hydrate growth rate and increasing the number of hydrate cavities. Additionally, BS demonstrated a biodegradability exceeding 60% within 28 days. Toxicity assessments confirmed BS's biocompatibility, with cell viability above 70% for skin and lung cells at concentrations up to 160 and 80 µg/mL, respectively. BS showed significant potential as an environmentally friendly alternative to synthetic surfactants like SDS for methane storage. These findings suggest that the synthesis of effective, such as BS, holds promise for diverse applications, including seawater desalination, carbon capture, and gas storage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=solidified%20methane" title="solidified methane">solidified methane</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20storage" title=" gas storage"> gas storage</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20hydrates" title=" gas hydrates"> gas hydrates</a>, <a href="https://publications.waset.org/abstracts/search?q=green%20surfactant" title=" green surfactant"> green surfactant</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20hydrate%20promoter" title=" gas hydrate promoter"> gas hydrate promoter</a>, <a href="https://publications.waset.org/abstracts/search?q=computational%20simulation" title=" computational simulation"> computational simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=sustainability" title=" sustainability"> sustainability</a> </p> <a href="https://publications.waset.org/abstracts/195035/energy-efficient-storage-of-methane-using-biosurfactant-in-the-form-of-clathrate-hydrate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/195035.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">1</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5945</span> Land Cover Classification System for the Estimation of Carbon Storage in Terrestrial Ecosystems</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lei%20Zhang">Lei Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The carbon cycle greatly influences global change, and the land cover changes contribute to the status and rate of the carbon budget in ecosystems. This paper proposes a land cover classification system for mapping land cover, the national ecological environment assessment, and estimating carbon storage in ecosystems. The classification system consists of basic land cover classes at levels Ⅰ and Ⅱ and auxiliary features at level III. The basic 38 classes characterizing land cover features are derived from 19 criteria referring to composition, structure, pattern, phenology, etc. The basic classes reflect the status of carbon storage in ecosystems. The auxiliary classes at level III complement the attributes of higher levels by 9 criteria. The 5 environmental criteria of temperature, moisture, landform, aspect and slope mainly reflect the potential and intensity of carbon storage in ecosystems. The disturbance of vegetation succession caused by land use type influences the vegetation carbon budget. The other 3 vegetation cover criteria, growth period, and species characteristics further refine the vegetation types. The hierarchical structure of the land cover map (the classes of levels Ⅰ and Ⅱ) is independent of the products of level III, which is helpful for land cover product management and applications. The classification system has been adopted in the Chinese national land cover database for the carbon budget in ecosystems at a 30 m scale. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=classification%20system" title="classification system">classification system</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20cover" title=" land cover"> land cover</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem" title=" ecosystem"> ecosystem</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20storage" title=" carbon storage"> carbon storage</a>, <a href="https://publications.waset.org/abstracts/search?q=object%20based" title=" object based"> object based</a> </p> <a href="https://publications.waset.org/abstracts/182404/land-cover-classification-system-for-the-estimation-of-carbon-storage-in-terrestrial-ecosystems" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182404.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">70</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5944</span> Statistical Analysis and Optimization of a Process for CO2 Capture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muftah%20H.%20El-Naas">Muftah H.

The present study evaluates and optimizes CO<sub>2</sub> capture through a process, where carbon dioxide is passed into pH adjusted high salinity water and reacted with sodium chloride to form a precipitate of sodium bicarbonate. This process is based on a modified Solvay process with higher CO<sub>2</sub> capture efficiency, higher sodium removal, and higher pH level without the use of ammonia. The process was tested in a bubble column semi-batch reactor and was optimized using response surface methodology (RSM). CO<sub>2</sub> capture efficiency and sodium removal were optimized in terms of major operating parameters based on four levels and variables in Central Composite Design (CCD). The operating parameters were gas flow rate (0.5–1.5 L/min), reactor temperature (10 to 50 <sup>o</sup>C), buffer concentration (0.2-2.6%) and water salinity (25-197 g NaCl/L). The experimental data were fitted to a second-order polynomial using multiple regression and analyzed using analysis of variance (ANOVA). The optimum values of the selected variables were obtained using response optimizer. The optimum conditions were tested experimentally using desalination reject brine with salinity ranging from 65,000 to 75,000 mg/L. The CO<sub>2</sub> capture efficiency in 180 min was 99% and the maximum sodium removal was 35%. The experimental and predicted values were within 95% confidence interval, which demonstrates that the developed model can successfully predict the capture efficiency and sodium removal using the modified Solvay method. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CO2%20capture" title="CO2 capture">CO2 capture</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20desalination" title=" water desalination"> water desalination</a>, <a href="https://publications.waset.org/abstracts/search?q=Response%20Surface%20Methodology" title=" Response Surface Methodology"> Response Surface Methodology</a>, <a href="https://publications.waset.org/abstracts/search?q=bubble%20column%20reactor" title=" bubble column reactor"> bubble column reactor</a> </p> <a href="https://publications.waset.org/abstracts/45373/statistical-analysis-and-optimization-of-a-process-for-co2-capture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45373.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5943</span> Restored CO₂ from Flue Gas and Utilization by Converting to Methanol by 3 Step Processes: Steam Reforming, Reverse Water Gas Shift and Hydrogenation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rujira%20Jitrwung">Rujira Jitrwung</a>, <a href="https://publications.waset.org/abstracts/search?q=Kuntima%20Krekkeitsakul"> Kuntima Krekkeitsakul</a>, <a href="https://publications.waset.org/abstracts/search?q=Weerawat%20Patthaveekongka"> Weerawat Patthaveekongka</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiraphat%20Kumpidet"> Chiraphat Kumpidet</a>, <a href="https://publications.waset.org/abstracts/search?q=Jarukit%20Tepkeaw"> Jarukit Tepkeaw</a>, <a href="https://publications.waset.org/abstracts/search?q=Krissana%20Jaikengdee"> Krissana Jaikengdee</a>, <a href="https://publications.waset.org/abstracts/search?q=Anantachai%20Wannajampa"> Anantachai Wannajampa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Flue gas discharging from coal fired or gas combustion power plant contains around 12% Carbon dioxide (CO₂), 6% Oxygen (O₂), and 82% Nitrogen (N₂).CO₂ is a greenhouse gas which has been concerned to the global warming. Carbon Capture, Utilization, and Storage (CCUS) is a topic which is a tool to deal with this CO₂ realization. Flue gas is drawn down from the chimney and filtered, then it is compressed to build up the pressure until 8 bar. This compressed flue gas is sent to three stages Pressure Swing Adsorption (PSA), which is filled with activated carbon. Experiments were showed the optimum adsorption pressure at 7bar, which CO₂ can be adsorbed step by step in 1st, 2nd, and 3rd stage, obtaining CO₂ concentration 29.8, 66.4, and 96.7 %, respectively. The mixed gas concentration from the last step is composed of 96.7% CO₂,2.7% N₂, and 0.6%O₂. This mixed CO₂product gas obtained from 3 stages PSA contained high concentration CO₂, which is ready to use for methanol synthesis. The mixed CO₂ was experimented in 5 Liter/Day of methanol synthesis reactor skid by 3 step processes as followed steam reforming, reverse water gas shift, and then hydrogenation. The result showed that proportional of mixed CO₂ and CH₄ 70/30, 50/50, 30/70 % (v/v), and 10/90 yielded methanol 2.4, 4.3, 5.6, and 6.0 Liter/day and save CO₂ 40, 30, 20, and 5 % respectively.

To address this issue, the integration of advanced materials like aerogels has emerged as a promising solution to enhance sustainability and environmental performance within the industry. This study thoroughly examines the application of aerogel-based technologies in the oil and gas sector, focusing particularly on their role in carbon capture and storage (CCS) initiatives. Aerogels, known for their exceptional properties, such as high surface area, low density, and customizable pore structure, have garnered attention for their potential in various CCS strategies. The review delves into various fabrication techniques utilized in producing aerogel materials, including sol-gel, supercritical drying, and freeze-drying methods, to assess their suitability for specific industry applications. Beyond fabrication, the practicality of aerogel materials in critical areas such as flow assurance, enhanced oil recovery, and thermal insulation is explored. The analysis spans a wide range of applications, from potential use in pipelines and equipment to subsea installations, offering valuable insights into the real-world implementation of aerogels in the oil and gas sector. The paper also investigates the adsorption and storage capabilities of aerogel-based sorbents, showcasing their effectiveness in capturing and storing carbon dioxide (CO₂) molecules. Optimization of pore size distribution and surface chemistry is examined to enhance the affinity and selectivity of aerogels towards CO₂, thereby improving the efficiency and capacity of CCS systems. Additionally, the study explores the potential of aerogel-based membranes for separating and purifying CO₂ from oil and gas streams, emphasizing their role in the carbon capture and utilization (CCU) value chain in the industry.

Global warming is mainly due to the emission of greenhouse gases (GHG) and carbon dioxide (CO<sub>2</sub>) is known to be the major contributor to the GHG emission profile. Whilst the energy sector is the primary source for CO<sub>2</sub> emission, Carbon Capture and Storage (CCS) are believed to be the solution for controlling this emission. Oxyfuel combustion (Oxy-combustion) is one of the major technologies for capturing CO<sub>2</sub> from power plants. For gas turbines, several Oxy-combustion power cycles (Oxyturbine cycles) have been investigated by means of thermodynamic analysis. NetPower cycle is one of the leading oxyturbine power cycles with almost full carbon capture capability from a natural gas fired power plant. In this manuscript, sensitivity analysis of the heat exchanger design in NetPower cycle is completed by means of process modelling. The heat capacity variation and supercritical CO<sub>2 </sub>with gaseous admixtures are considered for multi-zone analysis with Aspen Plus software. It is found that the heat exchanger design has a major role to increase the efficiency of NetPower cycle. The pinch-point analysis is done to extract the composite and grand composite curve for the heat exchanger. In this paper, relationship between the cycle efficiency and the minimum approach temperature (∆Tmin) of the heat exchanger has also been evaluated.  Increase in ∆Tmin causes a decrease in the temperature of the recycle flue gases (RFG) and an overall decrease in the required power for the recycled gas compressor. The main challenge in the design of heat exchangers in power plants is a tradeoff between the capital and operational costs. To achieve lower ∆Tmin, larger size of heat exchanger is required. This means a higher capital cost but leading to a better heat recovery and lower operational cost. To achieve this, ∆Tmin is selected from the minimum point in the diagrams of capital and operational costs. This study provides an insight into the NetPower Oxy-combustion cycle’s performance analysis and operational condition based on its heat exchanger design. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture%20and%20storage" title="carbon capture and storage">carbon capture and storage</a>, <a href="https://publications.waset.org/abstracts/search?q=oxy-combustion" title=" oxy-combustion"> oxy-combustion</a>, <a href="https://publications.waset.org/abstracts/search?q=netpower%20cycle" title=" netpower cycle"> netpower cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=oxy%20turbine%20cycles" title=" oxy turbine cycles"> oxy turbine cycles</a>, <a href="https://publications.waset.org/abstracts/search?q=zero%20emission" title=" zero emission"> zero emission</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20exchanger%20design" title=" heat exchanger design"> heat exchanger design</a>, <a href="https://publications.waset.org/abstracts/search?q=supercritical%20carbon%20dioxide" title=" supercritical carbon dioxide"> supercritical carbon dioxide</a>, <a href="https://publications.waset.org/abstracts/search?q=oxy-fuel%20power%20plant" title=" oxy-fuel power plant"> oxy-fuel power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=pinch%20point%20analysis" title=" pinch point analysis"> pinch point analysis</a> </p> <a href="https://publications.waset.org/abstracts/85218/sensitivity-analysis-of-the-heat-exchanger-design-in-net-power-oxy-combustion-cycle-for-carbon-capture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85218.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">204</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5940</span> Modeling Flow and Deposition Characteristics of Solid CO2 during Choked Flow of CO2 Pipeline in CCS</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Teng%20lin">Teng lin</a>, <a href="https://publications.waset.org/abstracts/search?q=Li%20Yuxing"> Li Yuxing</a>, <a href="https://publications.waset.org/abstracts/search?q=Han%20Hui">Han Hui</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhao%20Pengfei"> Zhao Pengfei</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhang%20Datong"> Zhang Datong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> With the development of carbon capture and storage (CCS), the flow assurance of CO2 transportation becomes more important, particularly for supercritical CO2 pipelines. The relieving system using the choke valve is applied to control the pressure in CO2 pipeline. However, the temperature of fluid would drop rapidly because of Joule-Thomson cooling (JTC), which may cause solid CO2 form and block the pipe. In this paper, a Computational Fluid Dynamic (CFD) model, using the modified Lagrangian method, Reynold's Stress Transport model (RSM) for turbulence and stochastic tracking model (STM) for particle trajectory, was developed to predict the deposition characteristic of solid carbon dioxide. The model predictions were in good agreement with the experiment data published in the literature. It can be observed that the particle distribution affected the deposition behavior. In the region of the sudden expansion, the smaller particles accumulated tightly on the wall were dominant for pipe blockage. On the contrary, the size of solid CO2 particles deposited near the outlet usually was bigger and the stacked structure was looser. According to the calculation results, the movement of the particles can be regarded as the main four types: turbulent motion close to the sudden expansion structure, balanced motion at sudden expansion-middle region, inertial motion near the outlet and the escape. Furthermore the particle deposits accumulated primarily in the sudden expansion region, reattachment region and outlet region because of the four type of motion. Also the Stokes number had an effect on the deposition ratio and it is recommended for Stokes number to avoid 3-8St. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carbon%20capture%20and%20storage" title="carbon capture and storage">carbon capture and storage</a>, <a href="https://publications.waset.org/abstracts/search?q=carbon%20dioxide%20pipeline" title=" carbon dioxide pipeline"> carbon dioxide pipeline</a>, <a href="https://publications.waset.org/abstracts/search?q=gas-particle%20flow" title=" gas-particle flow"> gas-particle flow</a>, <a href="https://publications.waset.org/abstracts/search?q=deposition" title=" deposition "> deposition </a> </p> <a href="https://publications.waset.org/abstracts/41429/modeling-flow-and-deposition-characteristics-of-solid-co2-during-choked-flow-of-co2-pipeline-in-ccs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41429.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">369</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5939</span> Solubility of Water in CO2 Mixtures at Pipeline Operation Conditions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Ahmad">Mohammad Ahmad</a>, <a href="https://publications.waset.org/abstracts/search?q=Sander%20Gersen"> Sander Gersen</a>, <a href="https://publications.waset.org/abstracts/search?q=Erwin%20Wilbers"> Erwin Wilbers</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbon capture, transport and underground storage have become a major solution to reduce CO2 emissions from power plants and other large CO2 sources. A big part of this captured CO2 stream is transported at high pressure dense phase conditions and stored in offshore underground depleted oil and gas fields. CO2 is also transported in offshore pipelines to be used for enhanced oil and gas recovery. The captured CO2 stream with impurities may contain water that causes severe corrosion problems, flow assurance failure and might damage valves and instrumentations. Thus, free water formation should be strictly prevented. The purpose of this work is to study the solubility of water in pure CO2 and in CO2 mixtures under real pipeline pressure (90-150 bar) and temperature operation conditions (5-35°C). A set up was constructed to generate experimental data. The results show the solubility of water in CO2 mixtures increasing with the increase of the temperature or/and with the increase in pressure. A drop in water solubility in CO2 is observed in the presence of impurities. The data generated were then used to assess the capabilities of two mixture models: the GERG-2008 model and the EOS-CG model. By generating the solubility data, this study contributes to determine the maximum allowable water content in CO2 pipelines. <p class="card-text"><strong>Keywords:</strong> <a
