processed oil shale is left as a solid waste. At the current processing rates, each year, 6–8 Mt of oil shale solid waste is produced. The ash formed at TPPs accounts for the majority of this oil shale solid waste, while approximately Mt of shale oil retorting waste is produced annually . •More than half of sulfur is left in the retorted oil shale both in “Kiviter” and SHC processes in Estonia – % •Most is in the form of sulfide and pyrite •The mechanism of sulfide leaching from retorted oil shale particles from Kiviter and Galoter process is different.

Determine the areal extent of the shale formations within the basin and estimate its overall thickness, in addition to other parameters. 3. Determine the prospective area deemed likely to be suitable for development based on depth, rock quality.
According to the simulation, t/h oil shale is retorted at °C to produce t/h shale oil, t/h retorting gas, t/h detrital oil shale, and t/h ash in the FS-OSR process. The utilities consumptions contain t/h water, MWh electricity, and t/h high-pressure by: Analysis and Evaluation of Oil Shale 6. Pyrolysis Oil shale can be retorted for producing shale oil. Depending on the shale oil composition, shale oil can be upgraded to obtain liquid fuels, such as in is done in China organic material. • Oil shale is quite different from tar sand. The organic substance of tar sand is bitumen.

EVALUATION OF RETORTED OIL SHALE AS A LINER MATERIAL FOR RETORTED SHALE DISPOSAL SITES By William J. Culbertson, Jr. Charles H. Habenicht James D. Mote Denver Research Institute Chemical and Materials Sciences Division University of Denver Denver, CO Cooperative Agreement CR Project Officer Edward R.
Bates Air and Energy Engineering Research. Autoclave mellowing of the burned Tosco material, however, pro- duced a high plasticity index material that may be blended with the silty un- burned Tosco II spent shale to produce a liner having (at least in the short term) both low permeability and good self- healing possibilities.
Surface soil of, and cm depths placed directly over Paraho processed oil shale showed appreciable reduction in nitrogenase (acetylene reduction), dehydrogenase, and phosphatase activities as compared with surface soil not in contact with processed shale.
(1) Shale has many preferred features (e.g., high CECs and easy compaction compared with clay) for landfill liners. However, shale alone is inadequate for use as landfill liner material because the plasticity index of shale is relatively small.
In contrast, clay that is suitable for landfill construction has a Cited by: 6. Retorted means 1. to reply to, usually in a sharp or retaliatory way; reply in kind to.

Chemical and mineral composition data on oil shale and retorted oil-shale wastes from Rulison, Colorado Open-File Report By: M.L. Tuttle, D.J. Ackerman, W.E. Dean, Paul H. It retains and accumulates within shale reservoirs with no migration or only primary migration.
Shale oil exists as free, dissolved or adsorbed liquid hydrocarbons in large fractures, matrix pores and micro-fractures in mudstone and shale formations.
(3) Organic matter plays an important role in the formation and evaluation of shale oil by: 3. An oil shale process is provided to retort oil shale and purify oil shale retort water. In the process, raw oil shale is retorted in an in situ underground retort or in an above ground retort to liberate shale oil, light hydrocarbon gases and oil shale retort water.
The retort water is separated from the shale oil and gases in a sump or in a fractionator or quench tower followed by an API oil Cited by: Hot retorted shale withdrawn from the pyrolysis vessel is treated in a separate container with an oxygenous gas so as to provide combustion of residual carbon retained on the shale, producing a high temperature gas for the production of some steam and for heating the non-oxygenous gas used in the oil shale retorting process in the first vessel.
The pyrobituminous oil shale from Irati geological formation is the most important Brazilian oil shale reserve, and its pyrolysis process yields a solid by-product known as retorted oil shale. Among alternative retorted oil shale reuses we hypothesize that it is safe and can either be used as raw material for agricultural inputs production or Author: Rosane Martinazzo, Carlos Augusto Posser Silveira, Adilson Luís Bamberg, Lizete Stumpf, Cristiane Ma.

The Piceance basin of northwestern Colorado contains large reserves of oil shale. Expected development of oil shale will affect the regional hydrologic systems because most oil-shale mines will require drainage; industrial requirements for water may be large; and oil-shale mines, wastes, and retorts may affect the quantity and quality of surface water and ground water.
Alflis Chalmers, Chevron STB, and Unishale B retorted shales are scheduled for future tests. Included in this project is evaluation of the impacts on leachate characteris- tics due to co-disposal of oil shale wastewater with the retorted shale.
Samples of co-disposal waste- waters have been obtained for Paraho (direct mode) and Lurgi retorting. Assuming an average shale grade of 30 gal/ ton and that 88% of the raw shale retorted will remain as spent shale to be disposed, then abouttons/day or i million tons per year of retorted oil shale, along with lesser quantities of other solid wastes, will require environmentally safe disposal.
Agarwal () estimates that if even one half of the planned oil shale production in the U.S. occurs, approximately million metric tons of retorted shale will be disposed of each year.
Mong the options for disposal are construction ' of compacted embankments as valley fills, side-hill fills, contoured mounds and mine backfills. COMPACTION AND RELATED PROPERTIES OF RETORTED OIL SHALE. As part of a project to demonstrate the feasibility of retorting oil shale by the Paraho vertical retort process, laboratory and field tests were performed to determine the physical and chemical properties of retorted oil shale for use as citeria for the design of full scale disposal by: 2.
ABSTRACTA grain-based microscale sealed vessel pyrolysis method to a whole rock sample from Pingliang (PL) marine shale was used to investigate the residual oil contents, fractional compositions and evolutions at different temperatures and maturities.
The maximum residual oil of PL marine shale can reach mg/g TOC. In oil window, PL marine shale residual oil is mainly Cited by: 1. William J.

The use of oil shale has been known for thousands of years. Inoil shale has been used as a commercial resource in France. It was mined and cooked in small quantities to produce oil to light oil lamps (Western Resources Advocates, ). Oil shale production had reached one million metric tons per year during the s and by File Size: 1MB.
