Shale oil, also called tight oil, is a type of oil that can be extracted by heating and upgrading kerogen trapped within shale formations - arrangements of fine-grained sedimentary rock. This type of oil resource is classified as an unconventional resource as the process of obtaining oil from these formations requires specialized processes. In surface processing, the oil shale retorting plants are called “oil shale retorts,” and have been operated in various countries for more than a hundred years. The oil shale retorts have many different types including directly and indirectly gas heated retorts and directly solid heated retorts. The typical retorts include the Paraho retort, 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. Since 2014, U.S. shale oil has created a boom in domestic crude oil production. Shale oil comprises more than a third of the onshore production of crude oil in the lower 48 states. As a result, the United States became the world’s largest crude-oil producer, according to the Energy Information Administration . As of 2008, most oil shale industries perform the shale oil extraction process after the rock is mined, crushed and transported to a retorting facility, although several experimental technologies perform the process in place . The temperature at which the kerogen decomposes into usable hydrocarbons varies with the time-scale of the process; in the above-ground retorting process decomposition begins at 300 °C (570 °F), but proceeds more rapidly and completely at higher temperatures. Heating oil shale to a sufficiently high temperature causes the chemical process of pyrolysis to yield a vapor. Upon cooling the vapor, the liquid shale oil—an unconventional oil—is separated from combustible oil-shale gas (the term shale gas can also refer to gas occurring naturally in shales). Such industrial-scale retorts are used in shale oil extraction, the production of charcoal and in the recovery of mercury in gold mining processes and hazardous waste. A process of heating oil shale to produce shale oil, oil shale gas, and spent shale is commonly called retorting.

to retort the oil shale. After initial start-up, the process uses the gas produced from retorting to supply all the heat required to extract the shale oil and gas from the.

Process oil shale into oil and gas with Enefit technology while utilizing the energy of heat for power production; Gives you an energy efficiency-optimized process The oil shale is heated in the retort (essentially a rotary kiln) to the reaction

Oil shale has a long past of production, starting in 1837 in France (Autun mines, 1974 Unocal develops new “Union B” retort process; Shell and Ashland join shale oil production technologies (Kiviter and Petroter). Developed indicators are a useful tool for improvement of fuel production technological processes and The use of oil shale for extraction of shale oil is more than 200 years old. processes are based on pyrolysis and/or distillation coal/oil shale in a retort to which

17 Nov 2008 The shale must be heated or “retorted”to extract petroleum-like distillates. Two basic retorting processes have been used — above-ground

extraction process of shale oil includes pyrolysis, hydrogenation and thermal dissolution of oil shale. Raw shale oil extracted from oil shale can be used as fuel oil Shale oil extraction is an industrial process for unconventional oil production. This process converts kerogen in oil shale into shale oil by pyrolysis, hydrogenation, or thermal dissolution.

U.S. shale oil output is surging, but American refineries can't process much more of the light crude, according to Morgan Stanley. There are also limited export opportunities for U.S. shale, which means light oil may soon have to trade at a discount to compete overseas.

processing oil shale to produce shale oil. Oil shale retorting is a very simple process since it basically involves only the application of heat to break down the Shale Oil Production - RETORTING. Oil shale processing, named as rule “ Retorting”, is PYROLYSIS process i.e. heating at 400-500C in non-oxygen
