The discharged spent oil bearing material is conveyed to a heat exchanger of the design shown in FIG. 4. The heat exchanger 400 contains sections 402, 404 and 406 maintained at 800° F., 500° F. and 200° F., respectively. Spent shale at 900° F. is …
The present work provides a detailed characterization and kinetic study of oil shale of Upper Assam, India. The physicochemical characteristics of oil shale were studied by proximate analysis, elemental analysis, Fourier transform infrared spectroscopy and X-ray diffraction. The physicochemical study showed the oil shale to be of siliceous type, sour in the presence of …
Oil shale is a type of sedimentary rock that is rich in kerogen. Kerogen is a part of rock that breaks down and releases hydrocarbons when heated. Hydrocarbons …
Spent oil shale samples were evaluated for potential chromium and vanadium release upon aerobic combustion used in power generation, or anaerobic retorting used in shale oil recovery. Combusted samples released more Cr than retorted or raw samples due to chromate formation. The behavior of vanadium was just opposite in that more V was released ...
Oil Shale Ex-Situ Process - Leaching Study of Spent Shale 48 | Page The product of oil shale process contain oil, gas, water and spent shale (solid residue). A dry and wet basis weight percentage of the composition of this type of shale are shown in Table 2.
Applications around Oil Shale: Together with competent partners within the ThyssenKrupp Group, Polysius works out coordinated process-technological and mechanical solutions for all aspects of oil shale processing.

The combustion temperature in the lift pipe and overhead vessel is from 1,000° F. to 1,400° F. The combusted spent sludge, combusted oil shale, and combusted spent shale dust are discharged through an outlet in the bottom of the overhead bin into heat carrier feed line 14 for use as solid heat carrier material in the retort.

The Agency is restating the RCRA status of spent oil shale from above ground oil shale operations based on the final Bevill rulemakings issued on September 1, 1989 (54 FR 36592), on January 23, 1990 (55 FR 2323) and on June 13, 1991 (56 FR 27300).
Co-pyrolysis of oil shale from different regions with spent oil shale from subcritical water extraction experiments is experimentally conducted using thermogravimetric analysis (TG). The mixture samples (oil shale/spent oil shale in blending ratio of 1:1) are heated from 30 up to 850 °C with heating rate of 5, 10 and 30 °C min−1, nitrogen flow rate of 30 mL min−1. Three …
In general, comminution costs (grinding energies) were between 25 and 50 kilowatt-hours per ton to reduce crushed oil shale to 20-..mu..m particle size. In some shale oil recovery processes, reduction to very fine particle sizes was necessary and resulted in increased oil yields that offset the cost of comminution.

oil shale (1). The spent shale varies in particle size and chemical properties depending on the grade of raw oil shale and type of processing method used (2). Spent shale can range in size from a very fine ash (minus No. 200 sieve) to relatively large chunks (9 in., 229 mm, or mo1·e). The chemical analysis of Fischer assay spent shales obtained
In this study, the efficiency of spent oil shale was assessed to remove the methyl red (MR) from aqueous solution under various chemical and physical parameters. The adsorption kinetics was assessed using the pseudo-first-order and pseudo-second-order models. The results indicated that increase in the level of adsorbent led to an increase in amount of dye removed …
As well, dry separation of oil shale waste with Bradford type of drum screen and rotary impact hammer crusher was tested. AS well dry separation with …
Fischer assay is a standardized empirical analysis for oil shale ores which is used to determine oil. yield, gas plus loss yield, pyrolysis water and spent shale yield using mass balance on dry b ...
Electron paramagnetic resonance (EPR) reveals the presence of free radicals in raw shale, shale oil, and spent shale. Thirty-four samples of raw shale, and the spent shale and shale oil produced in the Fischer assay of these raw shale samples were studied. There is a significant correlation between the gallons per ton oil yield as estimated by ...
Less than 3½ years after the shale revolution made the U.S. the world's largest oil producer, companies in the oil fields of Texas, New Mexico and North Dakota have tapped many of their best wells.
U.S. Shale Industry To Spend $83 Billion In 2022. By Rystad Energy - Dec 01, 2021, 4:00 PM CST. US shale expenditure is projected to surge 19.4% next year. Eagle Ford, Niobrara and Anadarko ...
The spent oil shale sample was sourced out from the labs of the Ministry of Energy and Mineral Resources in Amman, Jordan. The origin of the spent oil shale sample was Attarat Um Ghudran deposit. This deposit is a near surface and commercial deposit located 70 km south of Amman as shown in location 8 in Fig. 1. ...
Abstract. Disposal of massive amounts of spent shale will be required if an oil shale industry using surface retorting is developed. Field studies to model both low elevation (dry) and high elevation (moist) disposal sites were initiated in 1973 on 2 types of spent oil shale; coarse textured-US Bureau of Mines (USBM) and fine-textured-the Oil Shale Corporation (TOSCO).
