In 1910 Edeleanu founded "Allgemeine Gesellschaft für Chemische Industrie" in Germany, which, given the success of the name, changed to Edeleanu GmbH, in 1930. During Nazi's time, the company was bought by the Deutsche Erdöl-AG and Edeleanu, being of Jewish origin, moved back to Romania. After the war, the trademark was used by the successor company EDELEANU Gesellschaft mbH Alzenau (RWE) for many petroleum products, while the company was lately integrated as EDL in the <a href="/wiki/P%C3%B6rner_Group" title="Pörner Group">Pörner Group</a>.

Prior to World War II in the early 1940s, most petroleum refineries in the United States consisted simply of crude oil distillation units (often referred to as atmospheric crude oil distillation units). Some refineries also had <a href="/wiki/Vacuum_distillation" title="Vacuum distillation">vacuum distillation</a> units as well as <a href="/wiki/Thermal_cracking" class="mw-redirect" title="Thermal cracking">thermal cracking</a> units such as <a href="/wiki/Visbreaker" title="Visbreaker">visbreakers</a> (viscosity breakers, units to lower the <a href="/wiki/Viscosity" title="Viscosity">viscosity</a> of the oil). All of the many other refining processes discussed below were developed during the war or within a few years after the war. They became commercially available within 5 to 10 years after the war ended and the worldwide petroleum industry experienced very rapid growth. The driving force for that growth in technology and in the number and size of refineries worldwide was the growing demand for automotive gasoline and aircraft fuel. In the United States, for various complex economic and political reasons, the construction of new refineries came to a virtual stop in about the 1980s. However, many of the existing refineries in the United States have revamped many of their units and/or constructed add-on units in order to: increase their crude oil processing capacity, increase the <a href="/wiki/Octane" title="Octane">octane</a> rating of their product gasoline, lower the <a href="/wiki/Sulfur" title="Sulfur">sulfur</a> content of their diesel fuel and home heating fuels to comply with environmental regulations and comply with environmental air pollution and water pollution requirements.<figure class="mw-default-size mw-halign-center" typeof="mw:File/Thumb"><a href="/wiki/File:ExxonMobil_Baton_Rouge.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/5/59/ExxonMobil_Baton_Rouge.jpg/610px-ExxonMobil_Baton_Rouge.jpg" decoding="async" width="610" height="133" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/5/59/ExxonMobil_Baton_Rouge.jpg/915px-ExxonMobil_Baton_Rouge.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/5/59/ExxonMobil_Baton_Rouge.jpg/1220px-ExxonMobil_Baton_Rouge.jpg 2x" data-file-width="2853" data-file-height="621" /></a><figcaption><a href="/wiki/Baton_Rouge_Refinery" title="Baton Rouge Refinery">Baton Rouge Refinery</a> (the fifth-largest in the <a href="/wiki/United_States" title="United States">United States</a>)<a href="#cite_note-21">[21]</a></figcaption></figure> <div class="mw-heading mw-heading3"><h3 id="United_States">United States</h3>[<a href="/w/index.php?title=Oil_refinery&action=edit&section=2" title="Edit section: United States">edit</a>]</div> <style data-mw-deduplicate="TemplateStyles:r1236090951">.mw-parser-output .hatnote{font-style:italic}.mw-parser-output div.hatnote{padding-left:1.6em;margin-bottom:0.5em}.mw-parser-output .hatnote i{font-style:normal}.mw-parser-output .hatnote+link+.hatnote{margin-top:-0.5em}@media print{body.ns-0 .mw-parser-output .hatnote{display:none!important}}</style><div role="note" class="hatnote navigation-not-searchable">Main article: <a href="/wiki/Petroleum_refining_in_the_United_States" title="Petroleum refining in the United States">Petroleum refining in the United States</a></div> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Refinery,_Bayport_Industrial_Complex,_Harris_County,_Texas.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/b/b5/Refinery%2C_Bayport_Industrial_Complex%2C_Harris_County%2C_Texas.jpg/200px-Refinery%2C_Bayport_Industrial_Complex%2C_Harris_County%2C_Texas.jpg" decoding="async" width="200" height="139" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/b/b5/Refinery%2C_Bayport_Industrial_Complex%2C_Harris_County%2C_Texas.jpg/300px-Refinery%2C_Bayport_Industrial_Complex%2C_Harris_County%2C_Texas.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/b/b5/Refinery%2C_Bayport_Industrial_Complex%2C_Harris_County%2C_Texas.jpg/400px-Refinery%2C_Bayport_Industrial_Complex%2C_Harris_County%2C_Texas.jpg 2x" data-file-width="3594" data-file-height="2505" /></a><figcaption>Refinery, Bayport Industrial Complex, Harris County, Texas</figcaption></figure> In the 19th century, refineries in the U.S. processed crude oil primarily to recover the <a href="/wiki/Kerosene" title="Kerosene">kerosene</a>. There was no market for the more volatile fraction, including gasoline, which was considered waste and was often dumped directly into the nearest river. The invention of the automobile shifted the demand to gasoline and diesel, which remain the primary refined products today.<a href="#cite_note-22">[22]</a> Today, national and state legislation require refineries to meet stringent air and water cleanliness standards. In fact, oil companies in the U.S. perceive obtaining a permit to build a modern refinery to be so difficult and costly that no new refineries were built (though many have been expanded) in the U.S. from 1976 until 2014 when the small Dakota Prairie Refinery in North Dakota began operation.<a href="#cite_note-23">[23]</a> More than half the refineries that existed in 1981 are now closed due to low utilization rates and accelerating mergers.<a href="#cite_note-24">[24]</a> As a result of these closures total US refinery capacity fell between 1981 and 1995, though the operating capacity stayed fairly constant in that time period at around 15,000,000 barrels per day (2,400,000 m3/d).<a href="#cite_note-25">[25]</a> Increases in facility size and improvements in efficiencies have offset much of the lost physical capacity of the industry. In 1982 (the earliest data provided), the United States operated 301 refineries with a combined capacity of 17.9 million barrels (2,850,000 m3) of crude oil each calendar day. In 2010, there were 149 operable U.S. refineries with a combined capacity of 17.6 million barrels (2,800,000 m3) per calendar day.<a href="#cite_note-26">[26]</a> By 2014 the number of refinery had reduced to 140 but the total capacity increased to 18.02 million barrels (2,865,000 m3) per calendar day. Indeed, in order to reduce operating costs and depreciation, refining is operated in fewer sites but of bigger capacity. In 2009 through 2010, as revenue streams in the oil business dried up and profitability of oil refineries fell due to lower demand for product and high reserves of supply preceding the <a href="/wiki/Late-2000s_recession" class="mw-redirect" title="Late-2000s recession">economic recession</a>, oil companies began to close or sell the less profitable refineries.<a href="#cite_note-27">[27]</a> <div class="mw-heading mw-heading2"><h2 id="Operation">Operation</h2>[<a href="/w/index.php?title=Oil_refinery&action=edit&section=3" title="Edit section: Operation">edit</a>]</div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:Neste_Oil_Porvoo_refinery.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/0/02/Neste_Oil_Porvoo_refinery.jpg/220px-Neste_Oil_Porvoo_refinery.jpg" decoding="async" width="220" height="147" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/0/02/Neste_Oil_Porvoo_refinery.jpg/330px-Neste_Oil_Porvoo_refinery.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/0/02/Neste_Oil_Porvoo_refinery.jpg/440px-Neste_Oil_Porvoo_refinery.jpg 2x" data-file-width="800" data-file-height="533" /></a><figcaption><a href="/wiki/Neste_Oil" class="mw-redirect" title="Neste Oil">Neste Oil</a> refinery in <a href="/wiki/Porvoo" title="Porvoo">Porvoo</a>, Finland</figcaption></figure> Raw or unprocessed crude oil is not generally useful in industrial applications, although "light, sweet" (low viscosity, low <a href="/wiki/Sulfur" title="Sulfur">sulfur</a>) crude oil has been used directly as a burner fuel to produce steam for the propulsion of seagoing vessels.

The CDU distills the incoming crude oil into various fractions of different boiling ranges, each of which is then processed further in the other refinery processing units. The CDU is often referred to as the atmospheric distillation unit because it operates at slightly above atmospheric pressure.<a href="#cite_note-Handwerk2-1">[1]</a><a href="#cite_note-Leffler2-2">[2]</a><a href="#cite_note-kister-41">[41]</a> Below is a schematic flow diagram of a typical crude oil distillation unit. The incoming crude oil is preheated by exchanging heat with some of the hot, distilled fractions and other streams. It is then desalted to remove inorganic salts (primarily sodium chloride). Following the desalter, the crude oil is further heated by exchanging heat with some of the hot, distilled fractions and other streams. It is then heated in a fuel-fired furnace (fired heater) to a temperature of about 398 °C and routed into the bottom of the distillation unit. The cooling and condensing of the distillation tower overhead is provided partially by exchanging heat with the incoming crude oil and partially by either an air-cooled or water-cooled condenser. Additional heat is removed from the distillation column by a pumparound system as shown in the diagram below. As shown in the flow diagram, the overhead distillate fraction from the distillation column is naphtha. The fractions removed from the side of the distillation column at various points between the column top and bottom are called sidecuts. Each of the sidecuts (i.e., the kerosene, light gas oil, and heavy gas oil) is cooled by exchanging heat with the incoming crude oil. All of the fractions (i.e., the overhead naphtha, the sidecuts, and the bottom residue) are sent to intermediate storage tanks before being processed further. <figure class="mw-default-size mw-halign-center" typeof="mw:File/Thumb"><a href="/wiki/File:Refine.svg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/d/d7/Refine.svg/510px-Refine.svg.png" decoding="async" width="510" height="459" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/d/d7/Refine.svg/765px-Refine.svg.png 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/d/d7/Refine.svg/1020px-Refine.svg.png 2x" data-file-width="512" data-file-height="461" /></a><figcaption>Schematic flow diagram of a typical crude oil distillation unit as used in petroleum crude oil refineries</figcaption></figure> <div class="mw-heading mw-heading2"><h2 id="Location_of_refineries">Location of refineries</h2>[<a href="/w/index.php?title=Oil_refinery&action=edit&section=8" title="Edit section: Location of refineries">edit</a>]</div> A party searching for a site to construct a refinery or a chemical plant needs to consider the following issues: <ul><li>The site has to be reasonably far from residential areas.</li> <li>Infrastructure should be available for the supply of raw materials and shipment of products to markets.</li> <li>Energy to operate the plant should be available.</li> <li>Facilities should be available for waste disposal.</li></ul> Factors affecting site selection for oil refinery: <ul><li>Availability of land</li> <li>Conditions of traffic and transportation</li> <li>Conditions of utilities – power supply, water supply</li> <li>Availability of labours and resources</li></ul> Refineries that use a large amount of steam and cooling water need to have an abundant source of water. Oil refineries, therefore, are often located nearby navigable rivers or on a seashore, nearby a port. Such location also gives access to transportation by river or by sea. The advantages of transporting crude oil by pipeline are evident, and oil companies often transport a large volume of fuel to distribution terminals by pipeline. A pipeline may not be practical for products with small output, and railcars, road tankers, and barges are used. Petrochemical plants and solvent manufacturing (fine fractionating) plants need spaces for further processing of a large volume of refinery products, or to mix chemical additives with a product at source rather than at blending terminals. <div class="mw-heading mw-heading2"><h2 id="Safety_and_environment">Safety and environment</h2>[<a href="/w/index.php?title=Oil_refinery&action=edit&section=9" title="Edit section: Safety and environment">edit</a>]</div> <figure class="mw-default-size" typeof="mw:File/Thumb"><a href="/wiki/File:BP_PLANT_EXPLOSION-1_lowres2.jpg" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/7/71/BP_PLANT_EXPLOSION-1_lowres2.jpg/220px-BP_PLANT_EXPLOSION-1_lowres2.jpg" decoding="async" width="220" height="146" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/7/71/BP_PLANT_EXPLOSION-1_lowres2.jpg/330px-BP_PLANT_EXPLOSION-1_lowres2.jpg 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/7/71/BP_PLANT_EXPLOSION-1_lowres2.jpg/440px-BP_PLANT_EXPLOSION-1_lowres2.jpg 2x" data-file-width="504" data-file-height="334" /></a><figcaption>Fire-extinguishing operations after the <a href="/wiki/Texas_City_refinery_explosion" title="Texas City refinery explosion">Texas City refinery explosion</a></figcaption></figure> The refining process releases a number of different chemicals into the <a href="/wiki/Earth%27s_atmosphere" class="mw-redirect" title="Earth's atmosphere">atmosphere</a> (see <a href="/wiki/AP_42_Compilation_of_Air_Pollutant_Emission_Factors" title="AP 42 Compilation of Air Pollutant Emission Factors">AP 42 Compilation of Air Pollutant Emission Factors</a>) and a notable <a href="/wiki/Odor" title="Odor">odor</a> normally accompanies the presence of a refinery.

Because it leads to equipment failure, it is a primary driver for the refinery maintenance schedule. Corrosion-related direct costs in the U.S. petroleum industry as of 1996 were estimated at US$3.7 billion.<a href="#cite_note-:7-121">[121]</a><a href="#cite_note-128">[128]</a> Corrosion occurs in various forms in the refining process, such as pitting corrosion from water droplets, embrittlement from hydrogen, and stress corrosion cracking from sulfide attack.<a href="#cite_note-129">[129]</a> From a materials standpoint, carbon steel is used for upwards of 80 percent of refinery components, which is beneficial due to its low cost. <a href="/wiki/Carbon_steel" title="Carbon steel">Carbon steel</a> is resistant to the most common forms of corrosion, particularly from hydrocarbon impurities at temperatures below 205 °C, but other corrosive chemicals and environments prevent its use everywhere. Common replacement materials are <a href="/wiki/Low_alloy_steel" class="mw-redirect" title="Low alloy steel">low alloy steels</a> containing <a href="/wiki/Chromium" title="Chromium">chromium</a> and <a href="/wiki/Molybdenum" title="Molybdenum">molybdenum</a>, with <a href="/wiki/Stainless_steels" class="mw-redirect" title="Stainless steels">stainless steels</a> containing more chromium dealing with more corrosive environments. More expensive materials commonly used are <a href="/wiki/Nickel" title="Nickel">nickel</a>, <a href="/wiki/Titanium" title="Titanium">titanium</a>, and <a href="/wiki/Copper" title="Copper">copper</a> alloys. These are primarily saved for the most problematic areas where extremely high temperatures and/or very corrosive chemicals are present.<a href="#cite_note-130">[130]</a> Corrosion is fought by a complex system of monitoring, preventative repairs, and careful use of materials. Monitoring methods include both offline checks taken during maintenance and online monitoring. Offline checks measure corrosion after it has occurred, telling the engineer when equipment must be replaced based on the historical information they have collected. This is referred to as preventative management. Online systems are a more modern development and are revolutionizing the way corrosion is approached. There are several types of online corrosion monitoring technologies such as linear polarization resistance, <a href="/wiki/Electrochemical_noise" title="Electrochemical noise">electrochemical noise</a> and electrical resistance. Online monitoring has generally had slow reporting rates in the past (minutes or hours) and been limited by process conditions and sources of error but newer technologies can report rates up to twice per minute with much higher accuracy (referred to as real-time monitoring). This allows process engineers to treat corrosion as another process variable that can be optimized in the system. Immediate responses to process changes allow the control of corrosion mechanisms, so they can be minimized while also maximizing production output.<a href="#cite_note-:6-120">[120]</a> In an ideal situation having on-line corrosion information that is accurate and real-time will allow conditions that cause high corrosion rates to be identified and reduced. This is known as predictive management. Materials methods include selecting the proper material for the application. In areas of minimal corrosion, cheap materials are preferable, but when bad corrosion can occur, more expensive but longer-lasting materials should be used. Other materials methods come in the form of protective barriers between corrosive substances and the equipment metals. These can be either a lining of refractory material such as standard <a href="/wiki/Portland_cement" title="Portland cement">Portland cement</a> or other special acid-resistant cement that is shot onto the inner surface of the vessel. Also available are thin overlays of more expensive metals that protect cheaper metal against corrosion without requiring much material.<a href="#cite_note-131">[131]</a> <div class="mw-heading
