The Richmond Long Wharf is a major tanker terminal and port facility in Richmond, California .

#751248

106-824: The terminal receives petroleum, oil, byproduct and other petrochemical imports destined for the Chevron Richmond Refinery and other installations. It is located in the Point Richmond neighborhood. Chevron has cited the sensitivity of the general area in stonewalling attempts to complete the Bay Trail between Point Richmond and the Point Molate Area . 37°55′21″N 122°24′37″W  /  37.9224°N 122.4103°W  / 37.9224; -122.4103 This Contra Costa County, California building and structure-related article

212-465: A basic material used for making synthetic fibers , and was the first of its kind to produce the chemical from petroleum. The West Coast's first phenol plant was completed in 1954 for the production of lubricating oil and lubricating oil additive, resins and plastic, and plywood adhesives. A year later, another chemical plant for the manufacture of isophthalic was constructed, the first in the US. Isophthalic

318-522: A can factory, a barrel works, a machine shop and a tank car repair shop. When the United States entered World War I in 1917, the Richmond refinery became a critical producer of fuel for trucks, tankers, trains, and planes in the war effort. Historian Gerald White reported that the "high quality of the medicinal white oil developed at Richmond to take the place of Russian white oil, cut off by

424-530: A clean-up operation of the cove that cost between $ 20 and $ 30 million after being ordered to do so by the California Regional Water Quality Control Board's Bay Protection and Toxic Clean-up Program (which found Chevron liable for an additional $ 2.85 million in "natural resources damages.") In 2006 a local referendum (Measure T) proposed to raise the business tax. Chevron vehemently opposed the initiative and funded

530-445: A community-accessible website. Some citizens routinely patrol the area with air collection bins to measure the chemical content of the air. Between 1902 and 1987 the refinery released noxious chemicals into the surrounding environment with impunity. This came in the form of contaminated process water from the industrial facilities of the complex. There are unhealthy levels of polycyclic aromatic hydrocarbons (PAHs) and mercury in

636-548: A company previously formed by Claridge. Claridge's Patent Asphalte Company  – formed in 1838 for the purpose of introducing to Britain "Asphalte in its natural state from the mine at Pyrimont Seysell in France",  – "laid one of the first asphalt pavements in Whitehall". Trials were made of the pavement in 1838 on the footway in Whitehall, the stable at Knightsbridge Barracks, "and subsequently on

742-596: A day in the manufacture of petroleum products and other chemicals . The refinery's primary products are motor gasoline , jet fuel , diesel fuel and lubricants . The refinery was established several years before the City of Richmond was incorporated in 1905. Construction on the refinery began in 1901 between the Potrero Hills and the marshlands in the Point Richmond District ; the refinery

848-501: A flare event occurred. It was described by local television station KGO-TV channel 7 as a "large flare is producing flames". On September 3, 2016, black smoke could be seen coming from the refinery. NBC Bay Area reported that this was due to flaring. KGO, a local news station, counted a total of 38 flaring incidents in 2019. Most directly related to unexpected system upsets, per Chevron spokesperson. Residents are not informed. In August 2020, KRON 4, another local news station, reported

954-421: A key role in the facility's construction and implementation, being the project manager and the installation's first superintendent. Rheem continued on to be a key and historic civic figure in the City of Richmond. The presence of the burgeoning refinery transformed the small town of Richmond from a rural agricultural community with 200 residents to a company town of several thousand within a few years. Crude oil

1060-486: A large cloud of black smoke, visible from San Francisco. On November 27, 2023, a plume of black smoke was reported emanating from Chevron's Richmond refinery following a power outage at the facility. The smoke seen throughout the area began to billow from the facility Monday afternoon. This refinery receives small quantities (relative to their other sources) of crude oil from the Amazon region of South America, according to

1166-557: A massive flyer campaign, suggesting it would lead to evictions of seniors and closing of small businesses. The measure failed by 54%. However, in 2008 the measure was revived, modified to tax only large manufacturers; it passed by 51.5%. In 2009 the Chevron refinery agreed to pay the city of Richmond $ 28 million in back utility taxes. In 2011 Chevron unsuccessfully sued Contra Costa County for 73 million dollars claiming its property taxes were too high. The company's lawyers stated that

1272-518: A mixture of pitch and bitumen, was used in the Republic of Ragusa (now Dubrovnik , Croatia ) for tarring of ships. An 1838 edition of Mechanics Magazine cites an early use of asphalt in France. A pamphlet dated 1621, by "a certain Monsieur d'Eyrinys, states that he had discovered the existence (of asphaltum) in large quantities in the vicinity of Neufchatel", and that he proposed to use it in

1378-664: A moldable putty that hardened into handles. Earlier, less-careful excavations at Le Moustier prevent conclusive identification of the archaeological culture and age, but the European Mousterian style of these tools suggests they are associated with Neanderthals during the late Middle Paleolithic into the early Upper Paleolithic between 60,000 and 35,000 years before present. It is the earliest evidence of multicomponent adhesive in Europe. The use of natural bitumen for waterproofing and as an adhesive dates at least to

1484-525: A new fluid catalytic cracking unit capable of processing 40,000 barrels (6,400 m ) daily of feed stock, further adding to the high-octane gasolines being demanded in rapidly increasing quantities by modern, high-compression automobile engines. In 1965, a breakthrough came when the Richmond refinery opened the world's largest Isomax hydrocracking complex. The unit converts heavy petroleum oils to lighter stocks for gasoline and other higher valued products. The 62,000-barrel (9,900 m )-a-day unit increased

1590-476: A new Hydro Plant for the production of synthetic aviation gasoline . It was the first in the Western United States to produce synthetic gasoline by combining purified hydrogen gas with an unsaturated gas by-product from gasoline cracking operations. With the onset of World War II the refinery saw major changes. Many employees left for service in the U.S. military and close to 400 women joined

1696-472: A shipside hotel, ship chandlery , shook factory, barrel works, and some refinery administration offices. The trolley line was replaced by trucks and buses in 1948. The number of passenger cars in the United States rose from 1.6 million to 5.6 million from 1914 to 1918. Motor trucks, farm tractors, and aircraft all increased at a comparable rate. As a result, the demand for gasoline , lubricants and other petroleum products intensified. The Richmond refinery

1802-573: A sticky, black liquid or an apparently solid mass that behaves as a liquid over very large time scales. In American English , the material is commonly referred to as asphalt . Whether found in natural deposits or refined from petroleum, the substance is classed as a pitch . Prior to the 20th century, the term asphaltum was in general use. The word derives from the Ancient Greek word ἄσφαλτος ( ásphaltos ), which referred to natural bitumen or pitch. The largest natural deposit of bitumen in

1908-537: A temperature of 50 to 150 °C (120 to 300 °F). Due to pressure from the rising of the Rocky Mountains in southwestern Alberta, 80 to 55 million years ago, the oil was driven northeast hundreds of kilometres and trapped into underground sand deposits left behind by ancient river beds and ocean beaches, thus forming the oil sands. Bitumen use goes back to the Middle Paleolithic , where it

2014-424: A variety of ways – "principally in the construction of air-proof granaries, and in protecting, by means of the arches, the water-courses in the city of Paris from the intrusion of dirt and filth", which at that time made the water unusable. "He expatiates also on the excellence of this material for forming level and durable terraces" in palaces, "the notion of forming such terraces in the streets not one likely to cross

2120-495: Is a stub . You can help Misplaced Pages by expanding it . Chevron Richmond Refinery The Chevron Richmond Refinery is a 2,900-acre (1,200 ha) petroleum refinery in Richmond, California , on San Francisco Bay . It is owned and operated by Chevron Corporation and employs more than 1,200 workers, making it the city's largest employer. The refinery processes approximately 240,000 barrels (38,000 m ) of crude oil

2226-488: Is a chemical intermediate used in plastics and surface coatings. In 1960, construction began on a $ 17 million complex for production of para- and orthoxylenes , important chemical intermediates, at the Richmond refinery. Another major project increased the capacity for production of alpha olefins , used extensively in the manufacture of "soft" detergents , lubricant additives, plastics and plasticizers . None of these chemical plants are still in operation today except for

2332-424: Is a form of sandstone impregnated with bitumen. The oil sands of Alberta, Canada are a similar material. Neither of the terms "asphalt" or "bitumen" should be confused with tar or coal tars . Tar is the thick liquid product of the dry distillation and pyrolysis of organic hydrocarbons primarily sourced from vegetation masses, whether fossilized as with coal, or freshly harvested. The majority of bitumen, on

2438-432: Is a visually similar black, thermoplastic material produced by the destructive distillation of coal . During the early and mid-20th century, when town gas was produced, coal tar was a readily available byproduct and extensively used as the binder for road aggregates. The addition of coal tar to macadam roads led to the word " tarmac ", which is now used in common parlance to refer to road-making materials. However, since

2544-478: Is delivered by, and refined products distributed by, oil tankers using a long wharf extending into San Francisco Bay. Pipe lines connect the wharf to the refinery; and a parallel 42-inch (1.1 m) narrow gauge electric railway was built to transport packaged goods, shipboard supplies and personnel. The refinery shops built six power cars and three unpowered trailers for use under 2.25 miles (3.62 km) of overhead line . Trolley operation began in 1905 serving

2650-792: Is related to the English word mummy . The Egyptians' primary source of bitumen was the Dead Sea , which the Romans knew as Palus Asphaltites (Asphalt Lake). In approximately 40 AD, Dioscorides described the Dead Sea material as Judaicum bitumen , and noted other places in the region where it could be found. The Sidon bitumen is thought to refer to material found at Hasbeya in Lebanon. Pliny also refers to bitumen being found in Epirus . Bitumen

2756-461: Is sometimes sold combined with other materials, often without being labeled as anything other than simply "bitumen". Of particular note is the use of re-refined engine oil bottoms – "REOB" or "REOBs"  – the residue of recycled automotive engine oil collected from the bottoms of re-refining vacuum distillation towers, in the manufacture of asphalt. REOB contains various elements and compounds found in recycled engine oil: additives to

2862-563: Is sometimes specified by the term crude bitumen . Its viscosity is similar to that of cold molasses while the material obtained from the fractional distillation of crude oil boiling at 525 °C (977 °F) is sometimes referred to as "refined bitumen". The Canadian province of Alberta has most of the world's reserves of natural bitumen in the Athabasca oil sands , which cover 142,000 square kilometres (55,000 sq mi), an area larger than England . The Latin word traces to

2968-543: Is the prevalent term in much of the world; however, in American English , asphalt is more commonly used. To help avoid confusion, the terms "liquid asphalt", "asphalt binder", or "asphalt cement" are used in the U.S. to distinguish it from asphalt concrete. Colloquially, various forms of bitumen are sometimes referred to as " tar ", as in the name of the La Brea Tar Pits . Naturally occurring bitumen

3074-429: Is typical of some petroleum. The substance is soluble in carbon disulfide . It is commonly modelled as a colloid , with asphaltenes as the dispersed phase and maltenes as the continuous phase. "It is almost impossible to separate and identify all the different molecules of bitumen, because the number of molecules with different chemical structure is extremely large". Asphalt may be confused with coal tar , which

3180-501: Is used for the oil refinery product. Diluted bitumen (diluted with naphtha to make it flow in pipelines) is known as " dilbit " in the Canadian petroleum industry, while bitumen " upgraded " to synthetic crude oil is known as "syncrude", and syncrude blended with bitumen is called "synbit". "Bitumen" is still the preferred geological term for naturally occurring deposits of the solid or semi-solid form of petroleum. "Bituminous rock"

3286-552: The Occupational Safety and Health Administration fined Chevron $ 877,000 for "willfully failing to provide protective equipment for employees." Chevron employees had "repeatedly requested" protective equipment since the early 1980s but the company had refused despite more than 70 fires in the plant since 1984. Elizabeth Dole , the US Secretary of Labor , said: "OSHA's investigation makes clear that Chevron knew of

3392-541: The Proto-Indo-European root *gʷet- "pitch". The expression "bitumen" originated in the Sanskrit , where we find the words "jatu", meaning "pitch", and "jatu-krit", meaning "pitch creating", "pitch producing" (referring to coniferous or resinous trees). The Latin equivalent is claimed by some to be originally "gwitu-men" (pertaining to pitch), and by others, "pixtumens" (exuding or bubbling pitch), which

3498-544: The Uinta Basin in Utah, US. The Tar Sand Triangle deposit, for example, is roughly 6% bitumen. Bitumen may occur in hydrothermal veins . An example of this is within the Uinta Basin of Utah , in the US, where there is a swarm of laterally and vertically extensive veins composed of a solid hydrocarbon termed Gilsonite . These veins formed by the polymerization and solidification of hydrocarbons that were mobilized from

3604-425: The alpha privative , and σφάλλειν ( sphallein ), "to cause to fall, baffle, (in passive) err, (in passive) be balked of". The first use of asphalt by the ancients was as a cement to secure or join various objects, and it thus seems likely that the name itself was expressive of this application. Specifically, Herodotus mentioned that bitumen was brought to Babylon to build its gigantic fortification wall. From

3710-477: The 1970s, when natural gas succeeded town gas, bitumen has completely overtaken the use of coal tar in these applications. Other examples of this confusion include La Brea Tar Pits and the Canadian tar sands , both of which actually contain natural bitumen rather than tar. "Pitch" is another term sometimes informally used at times to refer to asphalt, as in Pitch Lake . For economic and other reasons, bitumen

3816-510: The 1999 explosion, residue was left in nearby water sources and soil which affected many nearby residents. The explosion accidentally sent out sulfuric gases into the air, affecting many nearby communities. A "shelter in place" advisory was issued, but proved ineffective because many residents were non-English speakers and were not able to get the adequate info through local media or the English only safety procedures that were announced. Chevron and county health services lacked consistence of informing

3922-586: The 19th century. One of the earliest surviving examples of its use can be seen at Highgate Cemetery where it was used in 1839 to seal the roof of the terrace catacombs. On the London stockmarket, there were various claims as to the exclusivity of bitumen quality from France, Germany and England. And numerous patents were granted in France, with similar numbers of patent applications being denied in England due to their similarity to each other. In England, "Claridge's

4028-882: The Bastenne company, were in production", with asphalt being laid as paving at Brighton, Herne Bay, Canterbury, Kensington, the Strand, and a large floor area in Bunhill-row, while meantime Claridge's Whitehall paving "continue(d) in good order". The Bonnington Chemical Works manufactured asphalt using coal tar and by 1839 had installed it in Bonnington . In 1838, there was a flurry of entrepreneurial activity involving bitumen, which had uses beyond paving. For example, bitumen could also be used for flooring, damp proofing in buildings, and for waterproofing of various types of pools and baths, both of which were also proliferating in

4134-515: The Bay Area and ranked among the major refineries in the U.S. In March 2014, the company launched a website to provide Richmond-area community news. [REDACTED] On April 10, 1989, an explosion and fire occurred in a cracking column at the refinery. A total of 8 workers and firefighters were injured. Three workers suffered second and third degree burns. As a result, in September 1989

4240-745: The Borealis Centre for Environmental and Trade Research. Chevron is currently implementing an Air Quality Monitoring program in the surrounding neighborhoods of North Richmond , Point Richmond and Atchison Village . This program is part of the Richmond Community Benefits Agreement (RCBA, Section 2.F(2)) for the Chevron Energy and Hydrogen Renewal Project. The Air Quality Monitoring Program will sample air quality using testing methods similar to those used by government agencies and publish these results on

4346-584: The Chevron Fire Department and other on site medical staff. A refinery spokeswoman stated that the fire erupted in the number 4 crude distillation unit, or CDU . Just before 6:30 p.m., an inspection crew discovered that there was a diesel leak in a line in the CDU—and that the leak was growing. The crew evacuated the area just before the diesel ignited, said Nigel Hearne, manager of the refinery. Three refinery workers were given first aid at

4452-533: The Chevron refinery with the Richmond Long Wharf . Chevron opposed the construction of this segment of the Bay Trail, citing security concerns, and stating that post-September 11 security requirements posed an issue. Supporters of the Bay Trail along with then California Lieutenant Governor John Garamendi pushed Chevron into accepting the construction of the Bay Trail in exchange for allowing

4558-468: The Greek, the word passed into late Latin, and thence into French ( asphalte ) and English ("asphaltum" and "asphalt"). In French, the term asphalte is used for naturally occurring asphalt-soaked limestone deposits, and for specialised manufactured products with fewer voids or greater bitumen content than the "asphaltic concrete" used to pave roads. Bitumen mixed with clay was usually called "asphaltum", but

4664-730: The Parc ( Ain ) and the Puy-de-la-Poix ( Puy-de-Dôme )", although it could also be made artificially. One of the earliest uses in France was the laying of about 24,000 square yards of Seyssel asphalt at the Place de la Concorde in 1835. Among the earlier uses of bitumen in the United Kingdom was for etching. William Salmon's Polygraphice (1673) provides a recipe for varnish used in etching, consisting of three ounces of virgin wax, two ounces of mastic , and one ounce of asphaltum. By

4770-531: The Richmond refinery, improving their flexibility for handling different types of crude oil, responding to changing product standards, installing energy conservation equipment, and complying with environmental or regulatory requirements. A $ 17 million direct digital computer control system was first installed in the Isomax plant, and later expanded to include all plants. This enabled the refinery to produce higher-grade products and reduce energy consumption. In 1984,

4876-418: The alpha olefin plant, which produces an intermediate chemical for the production of Techron , Chevron's gasoline additive . During the 1970s and 1980s as the dynamics of the United States petroleum industry were changing, the refinery was transformed to produce higher-value, higher-volume fuels and lubricating oils and to comply with increasingly stringent state and federal policies. These policies called for

4982-501: The amount of treated water discharged from 22 million US gallons (83,000 m ) to 5.6 million US gallons (21,000 m ). Additionally, in 1987 the refinery completed the deepwater discharge project moving the effluent discharge point from Castro Cove to deep water in San Pablo Bay to provide for greater dilution of remaining contaminants and minimize the impact on water quality. In 2007 and 2008, Chevron engaged in

5088-529: The appeal, stated that Chevron had manipulated data, refused to give the assessor's staff necessary information, and falsely characterized the nature of the county's assessment process, stating that Chevron's analysis was "fraught with materials that don’t satisfy evidentiary standards.” Around fifty protestors organized by the Richmond Progressive Alliance including Mayor McLaughlin and city council member Jovanka Beckles protested at

5194-415: The bill SB130 allowing Chevron to maintain a degree of trade secrets that was said to have a potential to compromise operational safety. Bitumen Bitumen ( UK : / ˈ b ɪ tʃ ʊ m ɪ n / BIH -chuum-in , US : / b ɪ ˈ tj uː m ɪ n , b aɪ -/ bih- TEW -min, by- ) is an immensely viscous constituent of petroleum . Depending on its exact composition it can be

5300-451: The brain of a Parisian of that generation". But the substance was generally neglected in France until the revolution of 1830 . In the 1830s there was a surge of interest, and asphalt became widely used "for pavements, flat roofs, and the lining of cisterns, and in England, some use of it had been made of it for similar purposes". Its rise in Europe was "a sudden phenomenon", after natural deposits were found "in France at Osbann ( Bas-Rhin ),

5406-444: The city from large industries like Chevron. In 2002, the 100th anniversary of the Richmond refinery, the plant had over 1,300 employees, covered 2,900 acres, operated 30 plants, and had the ability to move 340,000 barrels (54,000 m ) per day of raw materials and finished products across its long wharf. By 2006, the refinery had a capacity of 225,000 barrels (35,800 m ) a day and processed more crude oil than any other plant in

5512-546: The company pleaded no contest to six charges in connection with the fire, and agreed to pay $ 2 million in fines and restitution. On the first anniversary of the fire, 210 people were arrested while marching to protest safety issues at the refinery. Around the same time the settlement was announced, the Richmond city council voted to file suit against Chevron. The reasons for the suit included "a continuation of years of neglect, lax oversight and corporate indifference to necessary safety inspection and repairs." On December 18, 2014,

5618-565: The company to renew its 30-year lease on state tidelands that lie at the site of its port. In addition, the Richmond city council passed a resolution 8-1 directing mayor Gayle McLaughlin to ask the California State Land Use Commission to persuade Chevron to permit the trail. Chevron claimed that its total commitment in the Bay Trail amounted to $ 12.5 million, with $ 3 million being taken from Chevron's backtaxes, and $ 7.5 million worth of land being committed to

5724-478: The construction of a major lubricating oil manufacturing plant increased Richmond's lube oil base-stock output from 3,800 to 8,500 barrels (1,350 m ) a day, using hydrocracking and hydrorefining processes developed by Chevron Research. Later, in 1993, a major research breakthrough occurred when Chevron introduced Isodewaxing technology. This new technique maximized the production of high quality base oils while co-producing high-value light products and allowed for

5830-609: The deeper oil shales of the Green River Formation during burial and diagenesis . Bitumen is similar to the organic matter in carbonaceous meteorites . However, detailed studies have shown these materials to be distinct. The vast Alberta bitumen resources are considered to have started out as living material from marine plants and animals, mainly algae , that died millions of years ago when an ancient ocean covered Alberta. They were covered by mud, buried deeply over time, and gently cooked into oil by geothermal heat at

5936-411: The department gain greater prestige in support of the company's tenet, "Research First - Then Advertising," which ensured that a product was thoroughly tested before being introduced to the public. By 1924, the laboratory's staff grew to 75 skilled employees, who engaged in tests and experiments, not only to develop new uses for petroleum, but to improve existing processes. In 1938 the refinery constructed

6042-466: The economical production of base oils that meet specifications calling for lighter-viscosity lubricant grades. During the 1990s the refinery began producing Chevron Plus Unleaded gasoline, which replaced regular leaded gasoline in California in 1992. Methyl tert-butyl ether , or MTBE, was added as an oxygenate and to raise the octane number . MTBE was found to contaminate groundwater, and in 2004

6148-491: The estuarine habitats of Castro Cove and the San Pablo Creek Marsh adjacent to the refinery's runoff from their waste water outfall. The water is highly toxic to wildlife and is too polluted for fishing, swimming, or wading. Since 1987 the refinery has reduced the impact of discharged process water by improving water treatment to reduce contaminants, including metals, by approximately 80 percent and reducing

6254-483: The event, several of which were broadcast by the National Weather Service . BART shut down all local service. The fire was reported to be contained at around 10:40 PM, and the shelter-in-place order was lifted at 11:15 PM. Initial reports estimated that 11,000 people sought treatment at area hospitals, and later reports placed the number above 15,000 people. Six employees that were present at

6360-822: The fifth millennium BC, with a crop storage basket discovered in Mehrgarh , of the Indus Valley civilization , lined with it. By the 3rd millennium BC refined rock asphalt was in use in the region, and was used to waterproof the Great Bath in Mohenjo-daro. In the ancient Near East , the Sumerians used natural bitumen deposits for mortar between bricks and stones, to cement parts of carvings, such as eyes, into place, for ship caulking , and for waterproofing. The Greek historian Herodotus said hot bitumen

6466-495: The fifth edition in 1685, he had included more asphaltum recipes from other sources. The first British patent for the use of asphalt was "Cassell's patent asphalte or bitumen" in 1834. Then on 25 November 1837, Richard Tappin Claridge patented the use of Seyssel asphalt (patent #7849), for use in asphalte pavement, having seen it employed in France and Belgium when visiting with Frederick Walter Simms , who worked with him on

6572-542: The form of the adjective ἄσφαλἤς, ἐς signifying "firm", "stable", "secure", and the corresponding verb ἄσφαλίξω, ίσω meaning "to make firm or stable", "to secure". The word "asphalt" is derived from the late Middle English , in turn from French asphalte , based on Late Latin asphalton , asphaltum , which is the latinisation of the Greek ἄσφαλτος ( ásphaltos , ásphalton ), a word meaning "asphalt/bitumen/ pitch ", which perhaps derives from ἀ- , "not, without", i.e.

6678-519: The hearings, silently holding signs. The Assessment Appeals Board eventually found against Chevron's appeal, found that the county assessor had actually undervalued Chevron's refinery, and ordered Chevron to pay an additional $ 26.7 million in taxes, rather than receiving the $ 73 million refund Chevron sought. A portion of the San Francisco Bay Trail from Point Molate through to Point San Pablo crosses oil pipelines that connect

6784-523: The horse-drawn era, US streets were mostly unpaved and covered with dirt or gravel. Especially where mud or trenching often made streets difficult to pass, pavements were sometimes made of diverse materials including wooden planks, cobble stones or other stone blocks, or bricks. Unpaved roads produced uneven wear and hazards for pedestrians. In the late 19th century with the rise of the popular bicycle , bicycle clubs were important in pushing for more general pavement of streets. Advocacy for pavement increased in

6890-520: The introduction of asphalt to Britain. Dr T. Lamb Phipson writes that his father, Samuel Ryland Phipson, a friend of Claridge, was also "instrumental in introducing the asphalte pavement (in 1836)". Claridge obtained a patent in Scotland on 27 March 1838, and obtained a patent in Ireland on 23 April 1838. In 1851, extensions for the 1837 patent and for both 1838 patents were sought by the trustees of

Chevron lodged notices of contest against the penalties but in 1991 agreed to pay the U.S. Department of Labor $ 275,000 "in full financial settlement." On March 25, 1999, there was an explosion and fire at the refinery that spread noxious fumes and sent hundreds of Richmond residents to hospitals. After

7102-763: The oil deposits to be about 110 million years old. Two smaller but still very large formations occur in the Peace River oil sands and the Cold Lake oil sands , to the west and southeast of the Athabasca oil sands, respectively. Of the Alberta deposits, only parts of the Athabasca oil sands are shallow enough to be suitable for surface mining. The other 80% has to be produced by oil wells using enhanced oil recovery techniques like steam-assisted gravity drainage . Much smaller heavy oil or bitumen deposits also occur in

7208-424: The original oil and materials accumulating from its circulation in the engine (typically iron and copper). Some research has indicated a correlation between this adulteration of bitumen and poorer-performing pavement. The majority of bitumen used commercially is obtained from petroleum. Nonetheless, large amounts of bitumen occur in concentrated form in nature. Naturally occurring deposits of bitumen are formed from

7314-556: The other hand, was formed naturally when vast quantities of organic animal materials were deposited by water and buried hundreds of metres deep at the diagenetic point, where the disorganized fatty hydrocarbon molecules joined in long chains in the absence of oxygen. Bitumen occurs as a solid or highly viscous liquid. It may even be mixed in with coal deposits. Bitumen, and coal using the Bergius process , can be refined into petrols such as gasoline, and bitumen may be distilled into tar, not

7420-411: The other way around. The components of bitumen include four main classes of compounds: Bitumen typically contains, elementally 80% by weight of carbon; 10% hydrogen; up to 6% sulfur; and molecularly, between 5 and 25% by weight of asphaltenes dispersed in 90% to 65% maltenes. Most natural bitumens also contain organosulfur compounds , Nickel and vanadium are found at <10 parts per million, as

7526-426: The plant's gasoline output by 40%. A solvent de-asphalting plant and a hydrogen manufacturing plant were also constructed to support the Isomax and were the largest of their kind ever constructed. The post-war years were also marked by a dramatic increase in demand for petrochemicals to serve as the building blocks for hundreds of consumer products. In 1951, a new unit was constructed to manufacture paraxylene ,

7632-538: The postwar generation of higher-compression engines. In 1951, a 50,000-barrel (7,900 m ) residuum stripper was constructed to convert heavy residual fuel oil into lighter products. In 1959, the company made a major breakthrough when it developed the Isocracking process which uses catalysts to rearrange the existing molecules of heavy fuel oils to remove sulfur and convert low-value fuel oils into higher-yield products such as gasoline. The company also completed

7738-455: The production of aviation gasoline requested by the government. In 1945, the Richmond refinery won its fifth U.S. Army-Navy "E" award for its support of the military effort. Following the end of World War II, the refinery began a long-range modernization and expansion of its facilities to accommodate the new post-war consumer demands for petroleum products. The refinery constructed units that increased production of highly refined products for

7844-498: The project. A Chevron spokesperson stated that these numbers had been arrived at using Chevron assessors. Bruce Beyaert, head of the Trails for Richmond Action Committee (and former Chevron environmental executive) disagreed with Chevron's stated figures, saying that they were heavily inflated and amounted to "smoke and mirrors." Beyaert pointed to a 2001 joint trail study finding the trail easement south of I-580 worth $ 280,000, not

7950-442: The refinery to reduce air emissions and waste, treat water, and prevent oil spills . In order to comply with federal mandates for reduced-lead gasoline the refinery installed reforming units in 1971 to produce higher octane gasoline material. In 1975, the refinery added a desulfurization unit for the production of low-sulfur fuel oil, primarily to supply the growing needs of California electric utility companies. The expansion

8056-496: The refinery was not worth $ 3 billion in 2007 and 2009 as assessed, but instead only worth $ 1.8 and $ 1.15 billion respectively. During the hearings, Gayle McLaughlin , Mayor of Richmond, stated "If Chevron wins this appeal, it will mean layoffs, major cutbacks in services and would push us virtually to the edge of bankruptcy. Cities are suffering and Chevron is making billions of dollars." Kevin Lally, attorney acting for Richmond during

8162-492: The refinery workforce. The refinery shifted production to high- octane fuel and other products to meet military needs. In 1943 a toluene plant was constructed to supply the key ingredient for TNT and later, at the request of the U.S. military, was converted to production of 100- octane gasoline . The U.S. Secretaries of War and Navy and the Petroleum Administrator commended the refinery for exceeding

8268-554: The refinery. On April 15, 2013, the US Chemical Safety Board released their preliminary report citing Chevron for a chronic failure to replace aging equipment and called for an overhaul of regulatory oversight of the industry to prevent such accidents from happening again. In January 2015, the CSB released their final investigation report. Analysts predicted that the fire would cause an increase in gasoline prices in

8374-516: The remains of ancient, microscopic algae ( diatoms ) and other once-living things. These natural deposits of bitumen have been formed during the Carboniferous period, when giant swamp forests dominated many parts of the Earth. They were deposited in the mud on the bottom of the ocean or lake where the organisms lived. Under the heat (above 50 °C) and pressure of burial deep in the earth,

8480-730: The remains were transformed into materials such as bitumen, kerogen , or petroleum. Natural deposits of bitumen include lakes such as the Pitch Lake in Trinidad and Tobago and Lake Bermudez in Venezuela . Natural seeps occur in the La Brea Tar Pits and the McKittrick Tar Pits in California , as well as in the Dead Sea . Bitumen also occurs in unconsolidated sandstones known as "oil sands" in Alberta , Canada, and

8586-599: The residents about the importance to "shelter in place" in order to avoid inhalation of the harmful chemicals (over 200 chemicals) that were leaking into the communities. On August 6, 2012, a large fire was reported to have erupted at the refinery at about 6:15 PM. Flames were seen issuing from at least two of the refinery's towers, and a large plume of dark colored smoke covered the surrounding area. Contra Costa Health Services responded by notifying residents shelter in place . Local sirens were quickly activated, and numerous Emergency Alert System messages were issued throughout

8692-440: The scene of the fire suffered varying degrees of injury. Employee 1 received a minor burn to a small area on the left ear, Employee 2 suffered a small burn to the left wrist, Employee 3 suffered from abdominal discomfort. Employee 4's respiratory pathway was irritated, Employee 5 suffered blistering to the right leg from boot wear, and Employee 6 had a bruised finger. All of the injured employees were given on site medical treatment by

8798-463: The similar "tar sands" in Utah , US. The Canadian province of Alberta has most of the world's reserves, in three huge deposits covering 142,000 square kilometres (55,000 sq mi), an area larger than England or New York state . These bituminous sands contain 166 billion barrels (26.4 × 10 ^  m ) of commercially established oil reserves, giving Canada the third largest oil reserves in

8904-428: The space at the bottom of the steps leading from Waterloo Place to St. James Park". "The formation in 1838 of Claridge's Patent Asphalte Company (with a distinguished list of aristocratic patrons, and Marc and Isambard Brunel as, respectively, a trustee and consulting engineer), gave an enormous impetus to the development of a British asphalt industry". "By the end of 1838, at least two other companies, Robinson's and

9010-736: The stone artefacts, suggesting that bitumen was an important and frequently-used component of tool making for people in that region at that time. Geochemical analyses of the asphaltic residues places its source to localized natural bitumen outcroppings in the Bichri Massif, about 40 km northeast of the Umm el Tlel archeological site. A re-examination of artifacts uncovered in 1908 at Le Moustier rock shelters in France has identified Mousterian stone tools that were attached to grips made of ochre and bitumen. The grips were formulated with 55% ground goethite ochre and 45% cooked liquid bitumen to create

9116-486: The surface above underlying petroleum deposits. All three groups used the substance as an adhesive. It is found on many different artifacts of tools and ceremonial items. For example, it was used on rattles to adhere gourds or turtle shells to rattle handles. It was also used in decorations. Small round shell beads were often set in asphaltum to provide decorations. It was used as a sealant on baskets to make them watertight for carrying water, possibly poisoning those who drank

9222-454: The term is less commonly used today. In American English , "asphalt" is equivalent to the British "bitumen". However, "asphalt" is also commonly used as a shortened form of " asphalt concrete " (therefore equivalent to the British "asphalt" or "tarmac"). In Canadian English , the word "bitumen" is used to refer to the vast Canadian deposits of extremely heavy crude oil , while "asphalt"

9328-417: The terms asphalt and bitumen are often used interchangeably and refer both to natural and manufactured forms of the substance, although there is regional variation as to which term is most common. Worldwide, geologists tend to favor the term bitumen for the naturally occurring material. For the manufactured material, which is a refined residue from the distillation process of selected crude oils, bitumen

9434-453: The three million dollars Chevron assessed it at. Beyaert also states that there had previously been discussions to give land north of I-580 for free under an East Bay rails to trails project, land which Chevron's internal assessors valued at $ 4.5 million upon agreeing to the Bay Trail's construction. The portion of the trail in question has since been completed. In September 2014, the proponents of 1st Amendment free speech have argued against

9540-413: The war, caused an executive of E.R. Squibb & Sons to comment that the Richmond product was 'superior to the best oil' ever imported." At the end of the war the company shifted its focus back to basic product research and in 1919 constructed a well-equipped red brick laboratory building that still stands today. Development manager Ralph A. Halloran's emphasis on centralized, systematic research helped

9646-609: The water. Asphalt was used also to seal the planks on ocean-going canoes. Asphalt was first used to pave streets in the 1870s. At first naturally occurring "bituminous rock" was used, such as at Ritchie Mines in Macfarlan in Ritchie County, West Virginia from 1852 to 1873. In 1876, asphalt-based paving was used to pave Pennsylvania Avenue in Washington DC, in time for the celebration of the national centennial. In

9752-534: The western United States. A Chevron spokesperson later said that the fire was one factor among others, including the price of crude oil, that influenced prices. However, data collected by the California Energy Commission showed that increased production at other refineries more than made up for the Richmond loss, with 461,000 gallons of crude oil added to state refinery production during the week of August 3 through August 10, 2012. In 2013,

9858-525: The world is the Pitch Lake of southwest Trinidad , which is estimated to contain 10 million tons. About 70% of annual bitumen production is destined for road construction , its primary use. In this application, bitumen is used to bind aggregate particles like gravel and forms a substance referred to as asphalt concrete , which is colloquially termed asphalt . Its other main uses lie in bituminous waterproofing products, such as roofing felt and roof sealant. In material sciences and engineering ,

9964-600: The world. Although historically it was used without refining to pave roads, nearly all of the output is now used as raw material for oil refineries in Canada and the United States. The world's largest deposit of natural bitumen, known as the Athabasca oil sands , is located in the McMurray Formation of Northern Alberta. This formation is from the early Cretaceous , and is composed of numerous lenses of oil-bearing sand with up to 20% oil. Isotopic studies show

10070-882: Was a valuable strategic resource. It was the object of the first known battle for a hydrocarbon deposit – between the Seleucids and the Nabateans in 312 BC. In the ancient Far East, natural bitumen was slowly boiled to get rid of the higher fractions , leaving a thermoplastic material of higher molecular weight that, when layered on objects, became hard upon cooling. This was used to cover objects that needed waterproofing, such as scabbards and other items. Statuettes of household deities were also cast with this type of material in Japan, and probably also in China. In North America , archaeological recovery has indicated that bitumen

10176-457: Was also designed to process greater quantities of high-sulfur crudes and products that met environmental specifications. During the expansion the refinery also built two 750,000-barrel (119,000 m ) storage tanks , the largest in the United States, to receive marine cargos. In 1979, a worldwide shortage of crude oil, along with a shift in the availability of quality crudes, presented challenges to manufacturing operations. Chevron invested in

10282-492: Was in an excellent position with its plentiful crude oil , state-of-art equipment and prime location to capitalize on the increased demand for petroleum products on the West Coast. By 1915, the refinery spread across 435 acres (176 ha), employed 1,700 workers, and had a capacity of 60,000 barrels (9,500 m ) a day. Not only did the refinery produce transportation fuels, it also had a grease plant, an asphaltum plant,

10388-557: Was more widely used. However, the First World War ruined the Clarmac Company, which entered into liquidation in 1915. The failure of Clarmac Roads Ltd had a flow-on effect to Claridge's Company, which was itself compulsorily wound up, ceasing operations in 1917, having invested a substantial amount of funds into the new venture, both at the outset and in a subsequent attempt to save the Clarmac Company. Bitumen

10494-550: Was opened in 1902. The refinery was built by Standard Oil and its first headquarters was in an abandoned farm house at the former site of the Peters and Silva Farms. The complex was described as "colossal" at the time and to this day it remains a very large complex of its kind. In its first year of operation the plant could process 10,000 barrels (1,600 m ) of oil per day and had a tankage capacity of 185,000 barrels (29,400 m ) in that same first year. William Rheem played

10600-406: Was replaced with ethanol . In 2001 former vice mayor and councilman John Márquez stated that he did not think that the refinery's numerous toxic spills were intentional. He also stated that he thought the refinery was safe. He received campaign funding from BAPAC, that was backed by a $ 1,500 from Chevron Corporation. Marquez also opposed measure T and the 16,000,000 dollars that it would bring

10706-566: Was shaped into tool handles or used as an adhesive for attaching stone tools to hafts . The earliest evidence of bitumen use was discovered when archeologists identified bitumen material on Levallois flint artefacts that date to about 71,000 years BP at the Umm el Tlel open-air site, located on the northern slope of the Qdeir Plateau in el Kowm Basin in Central Syria. Microscopic analyses found bituminous residue on two-thirds of

10812-487: Was sometimes used to adhere stone projectile points to wooden shafts. In Canada, aboriginal people used bitumen seeping out of the banks of the Athabasca and other rivers to waterproof birch bark canoes , and also heated it in smudge pots to ward off mosquitoes in the summer. Bitumen was also used to waterproof plank canoes used by indigenous peoples in pre-colonial southern California. In 1553, Pierre Belon described in his work Observations that pissasphalto ,

10918-630: Was subsequently shortened to "bitumen", thence passing via French into English. From the same root is derived the Anglo Saxon word "cwidu" (Mastix), the German word "Kitt" (cement or mastic) and the old Norse word "kvada". The word "ašphalt" is claimed to have been derived from the Accadian term "asphaltu" or "sphallo", meaning "to split". It was later adopted by the Homeric Greeks in

11024-401: Was the type most used in the 1840s and 50s". In 1914, Claridge's Company entered into a joint venture to produce tar-bound macadam , with materials manufactured through a subsidiary company called Clarmac Roads Ltd. Two products resulted, namely Clarmac , and Clarphalte , with the former being manufactured by Clarmac Roads and the latter by Claridge's Patent Asphalte Co., although Clarmac

11130-552: Was thought in 19th century Britain to contain chemicals with medicinal properties. Extracts from bitumen were used to treat catarrh and some forms of asthma and as a remedy against worms, especially the tapeworm . The first use of bitumen in the New World was by aboriginal peoples. On the west coast, as early as the 13th century, the Tongva , Luiseño and Chumash peoples collected the naturally occurring bitumen that seeped to

11236-407: Was used as mortar in the walls of Babylon . The 1 kilometre (0.62 mi) long Euphrates Tunnel beneath the river Euphrates at Babylon in the time of Queen Semiramis ( c.  800 BC ) was reportedly constructed of burnt bricks covered with bitumen as a waterproofing agent. Bitumen was used by ancient Egyptians to embalm mummies. The Persian word for asphalt is moom , which
