Oil shale retorting process

F Retorting Technologies for Oil Shale HOT GAS RETORTING PROCESSES In the Paraho internal combustion retort a moving bed of shale travels downward and is heated by hot gas flowing upward through it. The hot gas is provided by combustion of hydrocarbon gas and char within the retort.

Individual ATP Processors can be designed to process up to ≈ 750 t/h of oil shale depending upon ore properties. Multiple ATP processing trains are installed in  A description is given of the oil shale retorting process by solid heat carrier Besides processing large-particle oil shale by vertical retorts, there are two. In-situ retorting is the technology for processing oil shale in-situ underground. This process obviates the problems of mining, handling, and disposing of large  Shale Oil Production - RETORTING. Oil shale processing, named as rule “ Retorting”, is PYROLYSIS process i.e. heating at 400-500C in non-oxygen 

This process converts kerogen in oil shale into shale oil by pyrolysis, In ex situ processing, also known as above-ground retorting, the oil shale is mined either 

Shale oil processing is defined as an industrial process to which raw shale oil is subjected to extract oil from it—basically a process to produce unconventional oil [1]. Because shale oil exists as solid sedimentary rocks, its extraction is more complex than extraction of conventional oil [1]. Oil shale must be mined using either underground- or surface-mining methods. After excavation, the oil shale must undergo retorting . This is when the mined rock is exposed to the process of pyrolysis -- applying extreme heat without the presence of oxygen to a substance, and producing a chemical change. The ATP Technology is a high performance surface retorting process for the production and recovery of hydrocarbons from mined oil shales. Oil shale is mined, crushed, and then retorted pyrolyzed in the ATP processor which uses the oil shale solids as the process heat carrier. The hydrocarbon vapours produced by the pyrolysis of the oil shale extracted from the ATP processor, condensed, and pumped to product tanks. This invention is a continuous retorting process for various high molecular weight organic materials, including oil shale, that yields an enhanced output of liquid product. The organic material, mineral matter, and an acidic catalyst, that appreciably adsorbs alkenes on surface sites at prescribed temperatures, are mixed and introduced into a pyrolyzer.

has been directed to the pyrolysis and retorting. Thus, tens of retorting processes can be found in oil shale literature. Some of these processes are currently 

4 Jan 2019 After the process of extraction is complete, oil shale undergoes a process known as retorting. During retorting, the shale containing the oil  Retorting is the cracking process used in shale oil refining, and first breaks down the kerogen to release hydrocarbons, and then further cracks the hydrocarbons  24 Mar 2005 This process is called retorting, and the vessel in which retorting takes place is known as a retort. The largest known oil shale deposits in the  An alternative but currently experimental process referred to as in situ retorting involves heating the oil shale while it is still underground and then pumping the 

At the same time, the Fushun Oil Shale Retorting Plant, using Fushun process technology, was established as a part of the Fushun Mining Group. It started production in 1992. In 2005, China became the largest shale oil producer in the world.

The ratio of oil shale gas to shale oil generally increases along with retorting temperatures. For a modern in situ process,  After excavation, the oil shale must undergo retorting. This is when the mined rock is exposed to the process of pyrolysis -- applying extreme heat without the  This retorting technology has been tested in Australia to process oil shale deposits found in Central Queensland but has been superseded by the Paraho retort  Publisher Summary. A very large number of different retorts have been suggested during the past 100 years for the aboveground processing of oil shale and a  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   Individual ATP Processors can be designed to process up to ≈ 750 t/h of oil shale depending upon ore properties. Multiple ATP processing trains are installed in 

In-situ retorting is the technology for processing oil shale in-situ underground. This process obviates the problems of mining, handling, and disposing of large 

In fact, special methods of retorting, such as the Hytort process, can increase oil yields of some oil shales by as much as three to four times the yield obtained by  has been directed to the pyrolysis and retorting. Thus, tens of retorting processes can be found in oil shale literature. Some of these processes are currently  degradation of ground-water quality both within and adjacent to the retort sites. The in-situ retorting process begins with fracturing of the oil shale to increase its. This paper examines the potential applicability of the process to two oil shale technology are that no mining is required and all energy required for retorting. This process converts kerogen in oil shale into shale oil by pyrolysis, In ex situ processing, also known as above-ground retorting, the oil shale is mined either  24 Nov 2015 Tar sands and oil shale in crude oil production. After mining, the oil shale is transported to a facility for retorting, a heating process that  POTENTIAL USES OF SPENT SHALE IN THE TREATMENT OF OIL SHALE RETORT WATERS. 1980.

Oil shale processing, named as rule “ Retorting”, is PYROLYSIS process i.e. heating at 400-500C in non-oxygen  Shale oil recovery processes are expected to have some unique air, water, and solid waste control 33 Appendix A. Oil Shale Retorting Processes . . 39 v  27 Sep 2005 Bubba of Belly of the Beast, who worked for two years on attempted commercialization of oil shale, describes the process this way: If you heat  Crude shale oil is the product of thermal processing of raw oil shale. who worked in mining, retorting, or refining, with maximum potential exposure to shale oil. The dried oil shale is combined with a solid heat carrier, which is essentially ash from a semicoke combustion process. The oil shale is heated in the retort (  4 Jan 2019 After the process of extraction is complete, oil shale undergoes a process known as retorting. During retorting, the shale containing the oil
