Inconel 625 was characterized by x-ray photoelectron spectroscopy (XPS) before and after high–temperature experiment in molten salt. The experiment was performed in a horizontal tube furnace molten salt reactor, at 450 °C in argon, at atmospheric pressure, for 150 hours. Industrially produced HITEC salt was used (NaNO3, KNO3, NaNO2). The XPS study was carried out using the ESCAProbe P apparatus (Omicron Nanotechnology Ltd.) equipped with a monochromatic Al Kα (1486.6 eV) X-ray source. The surface layer on alloy 625 after exposure contains only Na, C, O, and Ni (as NiOx) and Nb (as NbOx BE 206.8 eV). Ni was detected in the metallic state (Ni0 – Ni 2p BE-852.7 eV, NiOx - Ni 2p BE-854.7 eV) after a short Ar sputtering because the oxide layer on the surface was very thin. Nickel oxides can form a protective layer in the molten salt, but only future long-term exposures can determine the suitability of Inconel 625 for MSR. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Inconel%20625" title="Inconel 625">Inconel 625</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20salt" title=" molten salt"> molten salt</a>, <a href="https://publications.waset.org/abstracts/search?q=oxide%20layer" title=" oxide layer"> oxide layer</a>, <a href="https://publications.waset.org/abstracts/search?q=XPS" title=" XPS"> XPS</a> </p> <a href="https://publications.waset.org/abstracts/131354/x-ray-photoelectron-spectroscopy-characterization-of-the-surface-layer-on-inconel-625-after-exposition-in-molten-salt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131354.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">142</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">769</span> Corrosion Investigation of Superalloys, Molybdenum and TZM in Chloride Molten Salts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Craig%20Jantzen">Craig Jantzen</a>, <a href="https://publications.waset.org/abstracts/search?q=Tim%20Abram"> Tim Abram</a>, <a href="https://publications.waset.org/abstracts/search?q=Dirk%20Engelberg"> Dirk Engelberg</a>, <a href="https://publications.waset.org/abstracts/search?q=Hugues%20Lambert"> Hugues Lambert</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Cooper"> Daniel Cooper</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Molten salts are of high interest for use as coolants in nuclear reactors due to favourable high temperature and thermodynamic properties. The corrosive behaviour of molten salts however pose a materials integrity challenge. Three Ni / Ni-Fe based and two Mo based alloys have been exposed to molten eutectics (LiCl-KCl at 59.5:40.5 mol% and KCl-MgCl2 at 68:32 mol%) at 600°C and 800°C for durations up to 500hrs. Corrosion was observed to preferentially attack alloy constituents in order of their reactivity, with chromium the most vulnerable and depleted element. Alloy weight-loss per unit area was calculated to give linear corrosion rates, discounting any initial rapid corrosion of impurities. Further analysis was carried out using ICP-MS, SEM and EDX techniques to give a more detailed view of the corrosion mechanisms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molten%20salt" title="molten salt">molten salt</a>, <a href="https://publications.waset.org/abstracts/search?q=salt" title=" salt"> salt</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=high%20temperature" title=" high temperature"> high temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=licl" title=" licl"> licl</a>, <a href="https://publications.waset.org/abstracts/search?q=KCL" title=" KCL"> KCL</a>, <a href="https://publications.waset.org/abstracts/search?q=MgCl" title=" MgCl"> MgCl</a>, <a href="https://publications.waset.org/abstracts/search?q=molybdenum" title=" molybdenum"> molybdenum</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel" title=" nickel"> nickel</a>, <a href="https://publications.waset.org/abstracts/search?q=superalloys" title=" superalloys"> superalloys</a> </p> <a href="https://publications.waset.org/abstracts/60521/corrosion-investigation-of-superalloys-molybdenum-and-tzm-in-chloride-molten-salts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60521.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">450</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">768</span> Effect of Moisture Removal from Molten Salt on Corrosion of Alloys</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bhavesh%20D.%20Gajbhiye">Bhavesh D.

Corrosion of alloys in molten FLiNaK has however been recognized as a serious issue in the selection of structural materials. Corrosion experiments of alloys Inconel-625 (Fe-Ni alloy) and Hastelloy-B (Ni-Mo alloy) were performed in FLiNaK salt. The tests were carried out at a temperature of 650°C in graphite crucibles for 60 hours under inert atmosphere. Corrosion experiments were performed to study the effect of moisture removal in the salt by pre heating and vacuum drying. Weight loss of the alloy samples due to corrosion was measured and corrosion rate was estimated. The surface morphology of the alloy samples was analyzed by Scanning Electron Microscopy. A significant decrease in the corrosion rate was observed for the alloys studied in moisture removed salt. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FLiNaK" title="FLiNaK">FLiNaK</a>, <a href="https://publications.waset.org/abstracts/search?q=hastelloy" title=" hastelloy"> hastelloy</a>, <a href="https://publications.waset.org/abstracts/search?q=inconel" title=" inconel"> inconel</a>, <a href="https://publications.waset.org/abstracts/search?q=weight%20loss" title=" weight loss"> weight loss</a> </p> <a href="https://publications.waset.org/abstracts/6734/effect-of-moisture-removal-from-molten-salt-on-corrosion-of-alloys" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6734.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">495</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">767</span> The Effect of Internal Electrical Ion Mobility on Molten Salts through Atomistic Simulations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20F.%20Sanz-Navarro">Carlos F.

However, the energy density of the commercially used mixtures is still insufficient, and therefore, new systems based on latent heat storage (or phase change materials, PCM) are currently being investigated. In order to shed some light on the macroscopic physical properties of the molten salt phases, knowledge of the microscopic structure and dynamics is required. Several molecular dynamics (MD) simulations have been performed to model the thermal behavior of (Li,K)2CO3 mixtures. Up to this date, this particular molten salt mixture has not been extensively studied but it is of fundamental interest for understanding the behavior of other commercial salts. Molten salt diffusivities, the internal electrical ion mobility, and the physical properties of the solid-liquid phase transition have been calculated and compared to available data from literature. The effect of anion polarization and the application of a strong external electric field have also been investigated. The influence of electrical ion mobility on local composition is explained through the Chemla effect, well known in electrochemistry. These results open a new way to design optimal high temperature energy storage materials. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atomistic%20simulations" title="atomistic simulations">atomistic simulations</a>, <a href="https://publications.waset.org/abstracts/search?q=thermal%20storage" title=" thermal storage"> thermal storage</a>, <a href="https://publications.waset.org/abstracts/search?q=latent%20heat" title=" latent heat"> latent heat</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20salt" title=" molten salt"> molten salt</a>, <a href="https://publications.waset.org/abstracts/search?q=ion%20mobility" title=" ion mobility"> ion mobility</a> </p> <a href="https://publications.waset.org/abstracts/33033/the-effect-of-internal-electrical-ion-mobility-on-molten-salts-through-atomistic-simulations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33033.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">326</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">766</span> Corrosion Behavior of Steels in Molten Salt Reactors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jana%20Rejkov%C3%A1">Jana Rejková</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Kudrnov%C3%A1"> Marie Kudrnová</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper deals with the research of materials for one of the types of reactors IV. generation - reactor with molten salts. One of the advantages of molten salts applied as a coolant in reactors is the ability to operate at relatively low pressures, as opposed to cooling with water or gases. Compared to liquid metal cooling, which also allows lower operating pressures, salt melts are less prone to chemical reactions. The service life of the construction materials used is limited by the operating temperatures of the reactor and the content of impurities in the salts. For the research of corrosion resistance, an experimental device was designed and assembled, enabling exposure at high temperatures without access to oxygen in a flowing atmosphere of inert gas. Nickel alloys Inconel 601, 617, and 625 were tested in a mixture of chloride salts LiCl – KCl (58,2 - 41,8 wt. %). The experiment showed high resistance of the materials used and based on the results and XPS analysis, other construction materials were proposed for the experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molten%20salt" title="molten salt">molten salt</a>, <a href="https://publications.waset.org/abstracts/search?q=corrosion" title=" corrosion"> corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=nuclear%20reactor" title=" nuclear reactor"> nuclear reactor</a>, <a href="https://publications.waset.org/abstracts/search?q=nickel%20alloy" title=" nickel alloy"> nickel alloy</a> </p> <a href="https://publications.waset.org/abstracts/143859/corrosion-behavior-of-steels-in-molten-salt-reactors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/143859.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">165</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">765</span> Experimental Device to Test Corrosion Behavior of Materials in the Molten Salt Reactor Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jana%20Petru">Jana Petru</a>, <a href="https://publications.waset.org/abstracts/search?q=Marie%20Kudrnova"> Marie Kudrnova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The use of technologies working with molten salts is conditioned by finding suitable construction materials that must meet several demanding criteria. In addition to temperature resistance, materials must also show corrosion resistance to salts; they must meet mechanical requirements and other requirements according to the area of use – for example, radiation resistance in Molten Salt Reactors. The present text describes an experimental device for studying the corrosion resistance of candidate materials in molten mixtures of salts and is a partial task of the international project ADAR, dealing with the evaluation of advanced nuclear reactors based on molten salts. The design of the device is based on a test exposure of Inconel 625 in the mixture of salts Hitec in a high temperature tube furnace. The result of the pre-exposure is, in addition to the metallographic evaluation of the behavior of material 625 in the mixture of nitrate salts, mainly a list of operational and construction problems that were essential for the construction of the new experimental equipment. The main output is a scheme of a newly designed gas-tight experimental apparatus capable of operating in an inert argon atmosphere, temperature up to 600 °C, pressure 3 bar, in the presence of a corrosive salt environment, with an exposure time of hundreds of hours. This device will enable the study of promising construction materials for nuclear energy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=experimental%20device" title=" experimental device"> experimental device</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20salt" title=" molten salt"> molten salt</a>, <a href="https://publications.waset.org/abstracts/search?q=steel" title=" steel"> steel</a> </p> <a href="https://publications.waset.org/abstracts/131352/experimental-device-to-test-corrosion-behavior-of-materials-in-the-molten-salt-reactor-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131352.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">119</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">764</span> Thermo-Economic Analysis of a Natural Draft Direct Cooling System for a Molten Salt Power Tower</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huiqiang%20Yang">Huiqiang Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Domingo%20Santana"> Domingo Santana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Reducing parasitic power consumption of concentrating solar power plants is the main challenge to increase the overall efficiency, particularly for molten salt tower technology. One of the most effective approaches to reduce the parasitic power consumption is to implement a natural draft dry cooling system instead of the standard utilized mechanical draft dry cooling system. In this paper, a thermo-economic analysis of a natural draft direct cooling system was performed based on a 100MWe commercial scale molten salt power plant. In this configuration with a natural draft direct cooling system, the exhaust steam from steam turbine flows directly to the heat exchanger bundles inside the natural draft dry cooling tower, which eliminates the power consumption of circulation pumps or fans, although the cooling tower shadows a portion of the heliostat field. The simulation results also show that compared to a mechanical draft cooling system the annual solar field efficiency is decreased by about 0.2% due to the shadow, which is equal to a reduction of approximately 13% of the solar field area. As a contrast, reducing the solar field size by 13% in purpose in a molten salt power plant with a natural draft drying cooling system actually will lead to a reduction of levelized cost of electricity (LCOE) by about 4.06% without interfering the power generated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molten%20salt%20power%20tower" title="molten salt power tower">molten salt power tower</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20draft%20dry%20cooling" title=" natural draft dry cooling"> natural draft dry cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=parasitic%20power%20consumption" title=" parasitic power consumption"> parasitic power consumption</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20scale" title=" commercial scale"> commercial scale</a> </p> <a href="https://publications.waset.org/abstracts/93523/thermo-economic-analysis-of-a-natural-draft-direct-cooling-system-for-a-molten-salt-power-tower" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93523.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">168</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">763</span> Numerical Modeling of a Molten Salt Power Tower Configuration Adaptable for Harsh Winter Climate </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huiqiang%20Yang">Huiqiang Yang</a>, <a href="https://publications.waset.org/abstracts/search?q=Domingo%20Santana"> Domingo Santana</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a novel configuration which introduces a natural draft dry cooling tower system in a molten salt power tower. A three-dimensional numerical modeling was developed based on the novel configuration. A plan of building 20 new concentrating solar power plants has been announced by Chinese government in September 2016, and among these 20 new plants, most of them are located in regions with long winter and harsh winter climate. The innovative configuration proposed includes an external receiver concrete tower at the center, a natural draft dry cooling tower which is surrounding the external receiver concrete tower and whose shell is fixed on the external receiver concrete tower, and a power block (including a steam generation system, a steam turbine system and hot/cold molten salt tanks, and water treatment systems) is covered by the roof of the natural draft dry cooling tower. Heat exchanger bundles are vertically installed at the furthest edge of the power block. In such a way, all power block equipment operates under suitable environmental conditions through whole year operation. The monthly performance of the novel configuration is simulated as compared to a standard one. The results show that the novel configuration is much more efficient in each separate month in a typical meteorological year. Moreover, all systems inside the power block have less thermal losses at low ambient temperatures, especially in harsh winter climate. It is also worthwhile mentioning that a photovoltaic power plant can be installed on the roof of the cooling tower to reduce the parasites of the molten salt power tower. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=molten%20salt%20power%20tower" title="molten salt power tower">molten salt power tower</a>, <a href="https://publications.waset.org/abstracts/search?q=natural%20draft%20dry%20cooling" title=" natural draft dry cooling"> natural draft dry cooling</a>, <a href="https://publications.waset.org/abstracts/search?q=commercial%20scale" title=" commercial scale"> commercial scale</a>, <a href="https://publications.waset.org/abstracts/search?q=power%20block" title=" power block"> power block</a>, <a href="https://publications.waset.org/abstracts/search?q=harsh%20winter%20climate" title=" harsh winter climate"> harsh winter climate</a> </p> <a href="https://publications.waset.org/abstracts/79709/numerical-modeling-of-a-molten-salt-power-tower-configuration-adaptable-for-harsh-winter-climate" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/79709.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">341</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">762</span> CFD simulation of Near Wall Turbulence and Heat Transfer of Molten Salts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=C.%20S.%20Sona">C.

An important feature of these reactors will be the use of coolants at temperature higher than that being used in current nuclear reactors. The molten fluoride salt with a eutectic composition of 46.5% LiF - 11.5% NaF - 42% KF (mol %) commonly known as FLiNaK is a leading candidate for heat transfer coolant for these nuclear reactors. CFD simulations were carried out using large eddy simulations to investigate the flow characteristics of molten FLiNaK at 850°C at a Reynolds number of 10,500 in a cylindrical pipe. Simulation results have been validated with the help of mean velocity profile using direct numerical simulation data. Transient velocity information was used to identify and characterise turbulent structures which are important for transfer of heat across solid-fluid interface. A wavelet transform based methodology called wavelet transform modulus maxima was used to identify and characterise the singularities. This analysis was also used for flow visualisation, and also to calculate the heat transfer coefficient using small eddy model. The predicted Nusselt number showed good agreement with the available experimental data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FLiNaK" title="FLiNaK">FLiNaK</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title=" heat transfer"> heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20salt" title=" molten salt"> molten salt</a>, <a href="https://publications.waset.org/abstracts/search?q=turbulent%20structures" title=" turbulent structures"> turbulent structures</a> </p> <a href="https://publications.waset.org/abstracts/6732/cfd-simulation-of-near-wall-turbulence-and-heat-transfer-of-molten-salts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6732.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">449</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">761</span> Adsorption of Congo Red on MgO Nanoparticles Prepared by Molten Salt Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahbaa%20F.%20Bdewi">Shahbaa F.

Equilibrium experiments show the equilibrium was reached after 120 minutes and maximum adsorption efficiency was obtained in acidic media up to pH 6. Isotherm studies revealed the favorability of the adsorption process. The overall adsorption process was spontaneous and endothermic in nature with a maximum adsorption capacity of 1100 mg g-1 at 40°C as estimated from Langmuir isotherm. The adsorption kinetics was found to follow pseudo second-order rate equation. Relatively high activation energy (180.7 kJ mol-1) was obtained which is consistent with chemisorption mechanism for the adsorption process. <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=congo%20red" title=" congo red"> congo red</a>, <a href="https://publications.waset.org/abstracts/search?q=magnesium%20oxide" title=" magnesium oxide"> magnesium oxide</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a> </p> <a href="https://publications.waset.org/abstracts/62294/adsorption-of-congo-red-on-mgo-nanoparticles-prepared-by-molten-salt-method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/62294.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">209</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">760</span> Heat Transfer Performance for Turbulent Flow through a Tube Using Baffles</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Amina%20Benabderrahmane">Amina Benabderrahmane</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelylah%20Benazza"> Abdelylah Benazza</a>, <a href="https://publications.waset.org/abstracts/search?q=Samir%20Laouedj"> Samir Laouedj</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Three dimensional numerical investigation of heat transfer enhancement inside a non-uniformly heated parabolic trough solar collector fitted with baffles under turbulent flow was studied in the current paper.

Here, we report on the development of Al foams by a low cost and convenient technique of salt replication method with efficient control over size, geometry and distribution of the pores. Sodium bicarbonate was used as the foaming agent to form the porous refractory salt pattern. The mixed refractory salt slurry was microwave dried followed by sintering for selected time periods. Molten Al was infiltrated into the salt pattern in an inert atmosphere at a pressure of 2 bars. The final products were obtained by leaching out the refractory salt pattern.

With a growing world population and rising living standards, more and more salt is produced as waste through seawater desalination and potash mining processes. Unfortunately, most of the salt is directly disposed of into nature, where it causes environmental pollution. On the other hand, salt is affordable, is used therapeutically in various respiratory treatments, and can store humidity and heat. It was, therefore, necessary to determine salt materials already in use in building construction and their hygrothermal properties. This research aims to identify salt materials from different scientific branches and historically, to investigate their properties and prioritize the most promising salt materials for indoor applications in a thermal envelope. This was realized through literature review and classification of salt materials into three groups (raw salt materials, composite salt materials, and processed salt materials). The outcome of this research shows that salt has already been used as a building material for centuries and has a potential for future applications due to its hygrothermal properties in a thermal envelope. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salt" title="salt">salt</a>, <a href="https://publications.waset.org/abstracts/search?q=building%20material" title=" building material"> building material</a>, <a href="https://publications.waset.org/abstracts/search?q=hygrothermal%20properties" title=" hygrothermal properties"> hygrothermal properties</a>, <a href="https://publications.waset.org/abstracts/search?q=environment" title=" environment"> environment</a> </p> <a href="https://publications.waset.org/abstracts/131197/a-review-on-the-use-of-salt-in-building-construction" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/131197.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">169</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">756</span> Salt Scarcity and Crisis Solution in Islam Perspective</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Taufik%20Nugroho">Taufik Nugroho</a>, <a href="https://publications.waset.org/abstracts/search?q=Firsty%20Dzainuurahmana"> Firsty Dzainuurahmana</a>, <a href="https://publications.waset.org/abstracts/search?q=Tika%20Widiastuti"> Tika Widiastuti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The polemic about the salt crisis re-emerged, this is a classic problem in Indonesia and is still a homework that is not finished yet.

The contributing causes of shortage in water resources are sophisticated and have interactions with each other. The world-scale phenomena like global warming have led to an increase in air and ocean’s mean temperature, and this has already caused adverse effects on water resources. Other factors that exacerbated this situation such as population increase, changes in farming habits, rise in city dwellers, unbalanced request for energy and aquatic resources, improved living standards, new eating habits, increasing economic growth and consequently flourishing industrial activities, and different types of pollution such as air, water, etc., are compelling more pressure on our limited water resources. The report will briefly discuss climate change and its detrimental impacts on the water resources and finally will introduce two effective solutions to mitigate the consequences or even reverse them in the near to mid-term future: utilization of molten salt technology for storing huge amounts of generated electricity in solar power plants to accommodate power grid demands, and implementing fuel cell CHPs to reduce carbon emission, and consequently, mitigate the global warming phenomenon as the major root cause of threatening water resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=global%20warming" title=" global warming"> global warming</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resources" title=" water resources"> water resources</a>, <a href="https://publications.waset.org/abstracts/search?q=GHG%20emissions" title=" GHG emissions"> GHG emissions</a>, <a href="https://publications.waset.org/abstracts/search?q=fuel%20cell-CHP" title=" fuel cell-CHP"> fuel cell-CHP</a>, <a href="https://publications.waset.org/abstracts/search?q=solar%20power%20plant" title=" solar power plant"> solar power plant</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20salt%20storage" title=" molten salt storage"> molten salt storage</a> </p> <a href="https://publications.waset.org/abstracts/151405/the-effect-of-global-warming-on-water-resources" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151405.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">112</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">754</span> Halophilic Bacterium: A Review of New Studies</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bassam%20Al%20Johny">Bassam Al Johny</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Halophilic bacteria are organisms which thrive in salt-rich environments, such as salt lakes, solar salterns and salt mines which contain large populations of these organisms.

Salt stress caused severe impairments in photosynthetic variables like photosynthetic rate, chlorophyll fluorescence and chlorophyll content, being more pronounced in salt-sensitive genotype than in salt-tolerant.The activities of antioxidant enzymes (superoxide dismutase, catalase, ascorbate peroxidase and glutathione reductase) were higher in PK-327 than in PK-471 at various levels of salt treatments.It is concluded that tolerance capacity of PK-327 against salinity can be associated with the ability of this genotype in keeping an active photosynthetic system and strong antioxidant defence system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=salt%20stress" title="salt stress">salt stress</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean" title=" soybean"> soybean</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant" title=" antioxidant"> antioxidant</a>, <a href="https://publications.waset.org/abstracts/search?q=photosynthesis" title=" photosynthesis"> photosynthesis</a> </p> <a href="https://publications.waset.org/abstracts/16638/antioxidant-defence-systems-lipid-peroxidation-and-photosynthetic-variables-in-salt-sensitive-and-salt-tolerant-soybean-genotypes-in-response-to-salt-stress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16638.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">384</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">751</span> Study on the Effect of Coupling Fluid Compressible-Deformable Wall on the Flow of Molten Polymers</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Driouich">Mohamed Driouich</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Gueraoui"> Kamal Gueraoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Sammouda"> Mohamed Sammouda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this work is to establish a numerical code for studying the flow of molten polymers in deformable pipes.

Among molten fluoride salts, FLiNaK (LiF-NaF-KF: 46.5-11.5-42 mol %) is a potential candidate for the coolant due to its superior thermophysical properties such as high temperature stability, boiling point, volumetric heat capacity and thermal conductivity. Major technical challenge in implementation is the selection of structural material which can withstand corrosive nature of FLiNaK. Corrosion study of alloys SS 316L, Hastelloy B, Ni-201 was performed in molten FLiNaK at 650°C. Nickel was found to be more resistant to corrosive attack in molten fluoride medium. Corrosion experiments were performed to study the effect of nickel coating on corrosion of alloys SS 316L and Hastelloy B. Weight loss of the alloys due to corrosion was measured and corrosion rate was estimated. The surface morphology of the alloys was analyzed by Scanning Electron Microscopy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=corrosion" title="corrosion">corrosion</a>, <a href="https://publications.waset.org/abstracts/search?q=FLiNaK" title=" FLiNaK"> FLiNaK</a>, <a href="https://publications.waset.org/abstracts/search?q=hastelloy" title=" hastelloy"> hastelloy</a>, <a href="https://publications.waset.org/abstracts/search?q=weight%20loss" title=" weight loss"> weight loss</a> </p> <a href="https://publications.waset.org/abstracts/6733/effect-of-nickel-coating-on-corrosion-of-alloys-in-molten-salts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6733.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">441</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">749</span> FEM Simulations to Study the Effects of Laser Power and Scan Speed on Molten Pool Size in Additive Manufacturing</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yee-Ting%20Lee">Yee-Ting Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jyun-Rong%20Zhuang"> Jyun-Rong Zhuang</a>, <a href="https://publications.waset.org/abstracts/search?q=Wen-Hsin%20Hsieh"> Wen-Hsin Hsieh</a>, <a href="https://publications.waset.org/abstracts/search?q=An-Shik%20Yang"> An-Shik Yang </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Additive manufacturing (AM) is increasingly crucial in biomedical and aerospace industries. As a recently developed AM technique, selective laser melting (SLM) has become a commercial method for various manufacturing processes. However, the molten pool configuration during SLM of metal powders is a decisive issue for the product quality. It is very important to investigate the heat transfer characteristics during the laser heating process. In this work, the finite element method (FEM) software ANSYS<sup>®</sup> (work bench module 16.0) was used to predict the unsteady temperature distribution for resolving molten pool dimensions with consideration of temperature-dependent thermal physical properties of TiAl6V4 at different laser powers and scanning speeds. The simulated results of the temperature distributions illustrated that the ratio of laser power to scanning speed can greatly influence the size of molten pool of titanium alloy powder for SLM development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=additive%20manufacturing" title="additive manufacturing">additive manufacturing</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20element%20method" title=" finite element method"> finite element method</a>, <a href="https://publications.waset.org/abstracts/search?q=molten%20pool%20dimensions" title=" molten pool dimensions"> molten pool dimensions</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20laser%20melting" title=" selective laser melting"> selective laser melting</a> </p> <a href="https://publications.waset.org/abstracts/66793/fem-simulations-to-study-the-effects-of-laser-power-and-scan-speed-on-molten-pool-size-in-additive-manufacturing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/66793.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">286</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">748</span> The Expression Patterns of Thai Moderately Salt Tolerant Rice and High Salt Tolerant Rice in Response to Salt Stress</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kongngern%20K.">Kongngern K.</a>, <a href="https://publications.waset.org/abstracts/search?q=Homwonk%20C."> Homwonk C.</a>, <a href="https://publications.waset.org/abstracts/search?q=Theerakulpisut%20P."> Theerakulpisut P.</a>, <a href="https://publications.waset.org/abstracts/search?q=Roytrakul%20R."> Roytrakul R.</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rice cultivation is crucial globally, especially in Asia. Soil salinity poses a significant challenge for agricultural lands. Understanding the expression patterns of different rice varieties under salt stress can provide insights for developing more salt-tolerant cultivars. This study aims to compare the expression patterns of two rice varieties, Thai moderately salt-tolerant rice (Leaung Anan) and high salt-tolerant rice (Pokkali), in response to salt stress. By analyzing protein expression, the research seeks to identify key proteins associated with salt tolerance in rice. The expression patterns of the two rice varieties under salt stress were analyzed using 1D-SDS-PAGE, NanoLC-MS/MS, and MEV software. These methods enabled the researchers to assess the differential expression of proteins in the leaf sheaths of the rice plants. These results indicate that the study identified 18 proteins, exhibited significantly different expression patterns between the two rice cultivars under salt stress. Notably, certain proteins, such as Os05g0364500 and pr1-like protein, showed contrasting expression profiles in the two varieties. The up-regulated proteins, predominantly observed in the salt-tolerant rice, may contribute to the survival of rice plants under salt stress and may provide valuable insights for breeding programs aiming to enhance salt tolerancein rice cultivars. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=mass%20spectrometry" title="mass spectrometry">mass spectrometry</a>, <a href="https://publications.waset.org/abstracts/search?q=proteomics" title=" proteomics"> proteomics</a>, <a href="https://publications.waset.org/abstracts/search?q=rice%20leaf%20sheaths" title=" rice leaf sheaths"> rice leaf sheaths</a>, <a href="https://publications.waset.org/abstracts/search?q=salt%20stress" title=" salt stress"> salt stress</a> </p> <a href="https://publications.waset.org/abstracts/194601/the-expression-patterns-of-thai-moderately-salt-tolerant-rice-and-high-salt-tolerant-rice-in-response-to-salt-stress" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/194601.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">8</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">747</span> Sustainable Separation of Nicotine from Its Aqueous Solutions</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zoran%20Visak">Zoran Visak</a>, <a href="https://publications.waset.org/abstracts/search?q=Joana%20Lopes"> Joana Lopes</a>, <a href="https://publications.waset.org/abstracts/search?q=Vesna%20Najdanovic-Visak"> Vesna Najdanovic-Visak</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Within this study, the separation of nicotine from its aqueous solutions, using inorganic salt sodium chloride or ionic liquid (molten salt) ECOENG212® as salting-out media, was carried out. Thus, liquid-liquid equilibria of the ternary solutions (nicotine+water+NaCl) and (nicotine+water+ECOENG212®) were determined at ambient pressure, 0.1 MPa, at three temperatures. The related phase diagrams were constructed in two manners: by adding the determined cloud-points and by the chemical analysis of phases in equilibrium (tie-line data). The latter were used to calculate two important separation parameters - partition coefficients of nicotine and separation factors. The impacts of the initial compositions of the mother solutions and of temperature on the liquid-liquid phase separation and partition coefficients were analyzed and discussed. The results obtained clearly showed that both investigated salts are good salting-out media for the efficient and sustainable separation of nicotine from its solutions with water.

Owing to the complexity and limits of reliable measuring techniques, computational models of fluid flow are useful tools to study and quantify these problems. The overall objective of this study is to investigate the potential of a traveling magnetic field for an efficient operating control of the molten metal flow. A multidimensional numerical model will be developed for the calculations of Lorentz force, molten metal flow, and the related phenomenon. The numerical model is implemented in a laboratory-scale silicon crystallization furnace. This study presents the potential of traveling magnetic field approach for an efficient operating control of the molten flow. A numerical model will be used to study the effects of magnetic force applied on the molten flow, and their interdependencies. In this paper, coupled and decoupled, steady and unsteady models of molten flow and crystallization interface will be compared.

It is a highly stable and expensive salt. The production of Chevreul’s salt plays a key role in hiydrometallurgy. In recent years, researchs on this compound have been intensified. Silva et al. reported that this salt is thermally stable up to 200oC. Çolak et al. precipitated the Chevreul’s salt by using ammonia and sulphur dioxide. Çalban et al. obtained at the optimum conditions by passing SO2 from leach solutions with NH3-(NH4)2SO4.

The structure of Chevreul’s salt was examined by considering the previous studies. Thermodynamically, the most important precipitation parameters were pH, temperature, and sulphite-copper(II) ratio. The amount of Chevreul’s salt increased with increasing the temperature and sulphite-copper(II) ratio at the certain range, while it increased with decreasing the pH value at the chosen range. The best solution medium for recovery of Chevreul’s salt is sulphur dioxide gas-water system. Moreover, the soluble sulphite salts are used as efficient precipitating reagents. Chevreul’s salt is generally used to produce the highly pure copper powders from synthetic copper sulphate solutions and impure leach solutions. When the pH of the initial ammoniacal solution is greater than 8.5, ammonia in the medium is not free, and Chevreul’s salt from solution does not precipitate. In contrast, copper ammonium sulphide is precipitated. The pH of the initial solution containing ammonia for precipitating of Chevreul’s salt must be less than 8.5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chevreul%27s%20salt" title="Chevreul's salt">Chevreul's salt</a>, <a href="https://publications.waset.org/abstracts/search?q=production" title=" production"> production</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20sulfites" title=" copper sulfites"> copper sulfites</a>, <a href="https://publications.waset.org/abstracts/search?q=copper%20compound" title=" copper compound"> copper compound</a> </p> <a href="https://publications.waset.org/abstracts/52071/the-investigation-of-precipitation-conditions-of-chevreuls-salt" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/52071.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">249</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">742</span> Heat Transfer Analysis of a Multiphase Oxygen Reactor Heated by a Helical Tube in the Cu-Cl Cycle of a Hydrogen Production</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20W.%20Abdulrahman">Mohammed W. Abdulrahman</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the thermochemical water splitting process by Cu-Cl cycle, oxygen gas is produced by an endothermic thermolysis process at a temperature of 530<sup>o</sup>C. Oxygen production reactor is a three-phase reactor involving cuprous chloride molten salt, copper oxychloride solid reactant and oxygen gas. To perform optimal performance, the oxygen reactor requires accurate control of heat transfer to the molten salt and decomposing solid particles within the thermolysis reactor. In this paper, the scale up analysis of the oxygen reactor that is heated by an internal helical tube is performed from the perspective of heat transfer. A heat balance of the oxygen reactor is investigated to analyze the size of the reactor that provides the required heat input for different rates of hydrogen production. It is found that the helical tube wall and the service side constitute the largest thermal resistances of the oxygen reactor system. In the analysis of this paper, the Cu-Cl cycle is assumed to be heated by two types of nuclear reactor, which are HTGR and CANDU SCWR. It is concluded that using CANDU SCWR requires more heat transfer rate by 3-4 times than that when using HTGR. The effect of the reactor aspect ratio is also studied and it is found that increasing the aspect ratio decreases the number of reactors and the rate of decrease in the number of reactors decreases by increasing the aspect ratio. Comparisons between the results of this study and pervious results of material balances in the oxygen reactor show that the size of the oxygen reactor is dominated by the heat balance rather than the material balance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heat%20transfer" title="heat transfer">heat transfer</a>, <a href="https://publications.waset.org/abstracts/search?q=Cu-Cl%20cycle" title=" Cu-Cl cycle"> Cu-Cl cycle</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogen%20production" title=" hydrogen production"> hydrogen production</a>, <a href="https://publications.waset.org/abstracts/search?q=oxygen" title=" oxygen"> oxygen</a>, <a href="https://publications.waset.org/abstracts/search?q=clean%20energy" title=" clean energy"> clean energy</a> </p> <a href="https://publications.waset.org/abstracts/45088/heat-transfer-analysis-of-a-multiphase-oxygen-reactor-heated-by-a-helical-tube-in-the-cu-cl-cycle-of-a-hydrogen-production" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45088.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">261</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">741</span> Mechanistic Studies of Compacted and Sintered Rock Salt</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Claudia%20H.%20Swanson">Claudia H.

The sintering of rock salt powder compacts was systematically investigated using temperature and pressure as variables for the sinter process. The behavior of rock salt showed segregations of anhydrite, CaSO4 - the major impurity found in rock salt, to the grain boundaries between individual sodium chloride crystals. Powder compacts treated with lower pressures lost those anhydrite segregates over time while high pressure treated compacts remained with anhydrite segregates. The density reached in this study is 2.008 g cm-3 corresponding to a density of 92.5 % of the theoretical value. This high density is making the sintering a promising technique for rock salt as applications in underground appropriate environment. <p class="card-text"><strong>Keywords:</strong> <a
