Shell Spher Process
The Shell Spher process (Shell Pellet Heat Exchange Retorting) is an above ground fluidization bed retorting technology for shale oil extraction. It is classified as a hot recycled solids technology. Raw oil shale is crushed to a fine particles. Heat is transferred to oil shale by heat-carrying ceramic balls of size . Raw oil shale is preheated in fluidized bed at the temperature of in the case if oxygen is used as fluidizing medium, or at if non-oxidizing gases are used. Heated ceramic balls fall then through the bed in counter-current direction. The preheated oil shale is further heated in the retorting vessel. The retorted spent shale is cooled in a fast-fluidized bed by the recirculated cool pellets from the preheater; while cooling the spent shale ceramic balls are heated by the spent shale.

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 consortium for ...

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 Fushun ...

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 the 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. Decomposition is caused by mixing raw oil shale with hot oil shale ash generated by the combustion of carbonaceous residue (semi-coke) in the spent residue. The process was developed in the 1950s, and it is used commercially for shale oil production in Estonia. There are projects for further development of this technology and expansion of its usage, e.g., in Jordan and the USA. History Research on 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 the Academy of Sciences of the USSR. At the laboratory scale, the Galoter process was invented and developed in 1945–1946. The p ...

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] |
Alberta Taciuk Process
The Alberta Taciuk process (ATP; known also as the AOSTRA Taciuk process) is an above-ground dry thermal retorting technology for extracting oil from oil sands, oil shale and other organics-bearing materials, including oil contaminated soils, sludges and wastes. The technology is named after its inventor William Taciuk and the Alberta Oil Sands Technology and Research Authority. History The research and development of the ATP technology started in 1970. In 1975, its inventor, William Taciuk, formed the UMATAC Industrial Processes (now part of Polysius) to further its development. The first ATP pilot plant was constructed in 1977. The ATP was originally developed for pyrolysis of oil sand. However, its first commercial application in 1989 was dedicated to the environmental remediation of contaminated soils. From 1999 to 2004, ATP technology was used for shale oil extraction at the Stuart Oil Shale Plant in Australia. During that time, of shale oil was extracted be ...

Spent Shale
Spent shale or spent oil shale (also known as retorted shale) is a solid residue from the shale oil extraction process of producing synthetic shale oil from oil shale. It consists of inorganic compounds (minerals) and remaining organic matter known as char—a carbonaceous residue formed from kerogen. Depending on the extraction process and the amount of remaining organic matter, spent shale may be classified as oil shale coke, semi-coke or coke-ash residue, known also as oil shale ash. According to the European Union waste list all these types of spent shale are classified as hazardous waste. Oil shale coke is created by chamber ovens which were used for oil shale gas production. Vertical retorts create mainly semi-coke. Most solid heat carrier processes create coke-ash residue as the semi-coke created during the process is combusted for the process's energy needs. Spent shale can be used as ingredients in cement or brick manufacture. In Jordan, usage of spent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
