Union Process
The Union process was an above ground shale oil extraction technology for production of shale oil, a type of synthetic crude oil. The process used a vertical retort where heating causes decomposition of oil shale into shale oil, oil shale gas and Spent shale, spent residue. The particularity of this process is that oil shale in the retort moves from the bottom upward to the top, countercurrent to the descending hot gases, by a mechanism known as a rock pump. The process technology was invented by the American oil company Unocal Corporation in late 1940s and was developed through several decades. The largest oil shale retort ever built was the Union B type retort. History Union Oil Company of California (Unocal) started its oil shale activities in 1920s. In 1921, it acquired an oil shale tract in the Parachute, Colorado, Parachute Creek area of Colorado, southern Piceance Basin. The development of the Union process began in the late 1940s, when the Union A retort was designed. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Industry
The chemical industry comprises the companies that produce industrial chemicals. Central to the modern world economy, it converts raw materials (oil, natural gas, air, water, metals, and minerals) into more than 70,000 different products. The plastics industry contains some overlap, as some chemical companies produce plastics as well as chemicals. Various professionals are involved in the chemical industry including chemical engineers, chemists and lab technicians. History Although chemicals were made and used throughout history, the birth of the heavy chemical industry (production of chemicals in large quantities for a variety of uses) coincided with the beginnings of the Industrial Revolution. Industrial Revolution One of the first chemicals to be produced in large amounts through industrial processes was sulfuric acid. In 1736 pharmacist Joshua Ward developed a process for its production that involved heating saltpeter, allowing the sulfur to oxidize and combine with water ...

Office Of Naval Petroleum And Oil Shale Reserves
The United States Office of Naval Petroleum and Oil Shale Reserves, established in 1927, is part of the U.S. Department of Energy, responsible for analyzing and monitoring the U.S.'s oil shale reserves. The Pickett Act of 1910 authorized President William Howard Taft to withdraw large areas of potential oil-bearing lands in California and Wyoming as sources of fuel for the U.S. Navy. On July 2, 1910, President Taft set aside federal lands believed to contain oil as an emergency reserve for the U.S. Navy. The Reserves were initially under the control of the U.S. Department of the Interior, but in 1920, the U.S. Navy's Fuel Oil Office assumed responsibility for the Reserves. A year later, President Warren Harding placed the Reserves back under the Department of Interior, only to have the Teapot Dome Scandal force control back to the U.S. Navy. In 1927, the first Office of the Naval Petroleum and Oil Shale Reserves was officially created in the U.S. Navy. The U.S. Navy maint ...

TOSCO II Process
The TOSCO II process is an above ground retorting technology for shale oil extraction, which uses fine particles of oil shale that are heated in a rotating kiln. The particularity of this process is that it use hot ceramic balls for the heat transfer between the retort and a heater. The process was tested in a 40 tonnes per hour test facility near Parachute, Colorado. History TOSCO II process is a refinement of the Swedish Aspeco process. The Tosco Corporation purchased its patent rights in 1952. In 1956, the Denver Research Institute performed research and development of this technology, including testing of a 24 ton per day pilot plant, which operated until 1966. Later the technology development was continued under Tosco's own directions. In 1964 Tosco, Standard Oil of Ohio, and Cleveland Cliffs Iron Company formed Colony Development, a joint venture company to develop the Colony Shale Oil Project and to commercialize the TOSCO II technology. The project wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Petrosix
Petrosix is the world's largest surface oil shale pyrolysis retort with an diameter vertical shaft kiln, operational since 1992. It is located in São Mateus do Sul, Brazil, and it is owned and operated by the Brazil energy company Petrobras. Petrosix means also the Petrosix process, an externally generated hot gas technology of shale oil extraction. The technology is tailored to Irati oil shale formation, a Permian formation of the Paraná Basin. History Petrobras started oil shale processing activities in 1953 by developing Petrosix technology for extracting oil from oil shale of the Irati formation. A inside diameter semi-works retort (the Irati Profile Plant) with capacity of 2,400 tons per day, was brought on line in 1972, and began limited commercial operation in 1980. The first retort that used current Petrosix technology was a internal diameter retort pilot plant started in 1982. It was followed by a retort demonstration plant in 1984. A retort was brought into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraho Process
The Paraho process is an above ground retorting technology for shale oil extraction. The name "Paraho" is delivered from the words "''para homem''", which means in Portuguese "for mankind". History The Paraho process was invented by John B. Jones, Jr., later president of the Paraho Development Corporation, and developed by Development Engineering, Inc., in the late 1960s. Its design was based on a gas combustion retort developed by the United States Bureau of Mines and the earlier Nevada–Texas–Utah Retort. In the late 1940s, these retorts were tested in the Oil Shale Experiment Station at Anvil Points in Rifle, Colorado. In 1971, the Standard Oil of Ohio started to cooperate with Mr. John B. Jones providing financial support for obtaining an oil shale lease at Anvil Points. In May 1972, the lease was approved. Before leasing a track at Anvil Points, a test of using the Paraho Direct process for limestone calcination in cement kilns was carried out. The consorti ...

Kiviter Process
The Kiviter process is an above ground retorting technology for shale oil extraction. History The Kiviter process is based on the earlier vertical retort technology (Pintsch's generator). This technology underwent a long process of development. The early concept of central inlet of the heat carrier was later replaced by a concept of heat carrier gas cross flow in the retort. The Kiviter technology has been used in Estonia since 1921, when first experimental Kiviter retorts were built. The first commercial scale oil plant based on the Kiviter technology was built in 1924. From 1955 to 2003, Kiviter technology was used for oil shale processing also in Slantsy, Russia. Technology The Kiviter process is classified as an internal combustion technology. The Kiviter retort is a vertical cylindrical vessel that heats coarse oil shale with recycled gases, steam, and air. To supply heat, gases (including produced oil shale gas) and carbonaceous spent residue are burnt wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fushun Process
The Fushun process is an above-ground retorting technology for shale oil extraction. It is named after the main production site of Fushun, Liaoning province in northeastern China. History The Fushun process was developed and utilized for the extraction of shale oil in China during the mid-1920s. The commercial-scale utilization of the process began in 1930 with the construction of "Refinery No. 1". After World War II, the shale oil production was ceased, but 100 Fushun-type oil shale retorts were restored in 1949. In 1950, total 266 retorts were in operation, each with the capacity of 100–200 tons of shale oil per day. With the discovery of Daqing oil field in the 1960s, the shale oil production declined and Sinopec, an operator of shale oil production these times, shut down its oil shale operations in the beginning of the 1990s. At the same time, the Fushun Oil Shale Retorting Plant, using Fushun process technology, was established as a part of the Fushu ...

Galoter Process
The Galoter process (also known as TSK, UTT, or SHC; its newest modifications are called Enefit and Petroter) is a shale oil extraction technology for a production of shale oil, a type of synthetic crude oil. In this process, the oil shale is decomposed into shale oil, oil shale gas, and spent residue. A decomposition is caused by mixing raw oil shale with a hot oil shale ash, generated by combustion of carbonaceous residue ( semi-coke) in the spent residue. The process was developed in 1950s and it is used commercially for the shale oil production in Estonia. There are projects for further development of this technology and for expansion of its usage, e.g. in Jordan and USA. History Research of the solid heat carrier process for pyrolysis of lignite, peat, and oil shale started in 1944 at the G. M. Krzhizhanovsky Power Engineering Institute of Academy of Sciences of the USSR. At the laboratory scale, the Galoter process was invented and developed in 1945–1946. The proce ...

Ammonia
Ammonia is an inorganic compound of nitrogen and hydrogen with the formula . A stable binary hydride, and the simplest pnictogen hydride, ammonia is a colourless gas with a distinct pungent smell. Biologically, it is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to 45% of the world's food and fertilizers. Around 70% of ammonia is used to make fertilisers in various forms and composition, such as urea and Diammonium phosphate. Ammonia in pure form is also applied directly into the soil. Ammonia, either directly or indirectly, is also a building block for the synthesis of many pharmaceutical products and is used in many commercial cleaning products. It is mainly collected by downward displacement of both air and water. Although common in nature—both terrestrially and in the outer planets of the Solar System—and in wide use, ammonia is both caust ...

Hydrogen Sulfide
Hydrogen sulfide is a chemical compound with the formula . It is a colorless chalcogen-hydride gas, and is poisonous, corrosive, and flammable, with trace amounts in ambient atmosphere having a characteristic foul odor of rotten eggs. The underground mine gas term for foul-smelling hydrogen sulfide-rich gas mixtures is ''stinkdamp''. Swedish chemist Carl Wilhelm Scheele is credited with having discovered the chemical composition of purified hydrogen sulfide in 1777. The British English spelling of this compound is hydrogen sulphide, a spelling no longer recommended by the Royal Society of Chemistry or the International Union of Pure and Applied Chemistry. Hydrogen sulfide is toxic to humans and most other animals by inhibiting cellular respiration in a manner similar to hydrogen cyanide. When it is inhaled or it or its salts are ingested in high amounts, damage to organs occurs rapidly with symptoms ranging from breathing difficulties to convulsions and death. Despite this, the ...
