Shale Oil: Definition • Sedimentary rock with a high organic content – Organic matter is known as kerogen • Kerogen: – MW avg. =3000 – Approximate formula C200 H300 SN 5O11 1 1. Feng H.Y. Rates Of Pyrolysis Of Colorado shale oil. p. 732. American Institute Of Chemical Engineers Journal . Vol. 31 No. 5. 1985.


total shale oil from one ton of oil shale of the Baltic deposit constitutes 129– 131 kg, the output of pyrolysis gas or semicoke gas constitutes 35–36 nm3 (40.2–41.3 kg). The units of UTT-type can be practically used for oil shale with any calorific value, including low-calorific oil shale with the respective


The novel process is modeled, and next, the simulation is carried out to build its mass and energy balance. From the techno-economic point of view, the advantages of the novel process are demonstrated by comparison to the traditional Fushun-type oil shale retorting process. Results indicate that the novel process is promising because coupling ...


The AGR process includes mining the oil shale and retorting these mined deposits in heating vessels known as retorts. ... high operating and safety costs …


Shale will generally be mined by conventional room and pillar methods. Crushing is necessary before retorting. Shale is crushed in two stages—primary crushing at the mine and secondary crushing at the retort site. THE Central to the process is the Paraho vertical kiln shown in cutaway isometric in figure 1, It consists of a vertical vessel ...


1. Introduction. Oil shale is a highly ash-rich sedimentary rock enriched with combustible organic matter, .The majority of the organic matter in oil shale is kerogen,, which is insoluble in common organic solvents, .The kerogen component is about 3% to 15% in oil shale, and consist of complex organic compound in high molecular weight,, that is rich in aliphatic …


The process of shale oil production based on Fushun-type oil shale retorting technology is illustrated in Fig. 1, which is mainly divided into oil shale crush, screening, retorting, cooling-separation and recovery.After multiple crushing and screening, fine oil shale particles (diameter less than 8 mm) are transported to the power ...


The front-end process of oil shale crushing, drying, preheating, etc. is the same as the traditional Galoter process, but the difference is semi-coke combustion. One of the differences is that the combustion of the semi-coke and dry distillation gases takes place in a circulating fluidized bed. Another difference is that the shale is pyrolyzed ...


Shale rock crushing and grinding process. The whole process of shale comminution usually consists of primary crushing, secondary crushing and fine crushing. Shale rock of different sizes are inserted into the jaw crushers for size reduction. Generally grinding is carried out in one or two stages, while three grinding stages can also be performed.


The main hypotheses are related to usability of dry selective crushing and in situ separation of oil shale and limestone in the mine to support effective management of calorific value and backfilling.


The impacts of shale oil in the refining process The Impacts of Transporting Shale Oil Whether transporting crude via pipeline, truck, barge, or rail car, shale oil


Wet oil shale is fed into a Venturi dryer, where the hot flue gas from the heat recovery boiler evaporates the moisture. Downstream of the dryer, a cyclone separates the dried oil shale from the gas stream. The dried oil shale and solid heat carrier – the ash from the semi-coke combustion process – are fed into a retort.


Sohrab Zendehboudi PhD, Alireza Bahadori PhD, CEng, in Shale Oil and Gas Handbook, 2017. 2 Description of Oil Shale Processing. 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 …


Paraho Company, USA. The oil yield of this process is 90-95% of the Fischer Assay. The particle size of the feedstock in the moving bed is ... particles account for only about 75% of the crushing oil shale. Consequently, the moving bed retorting process must be integrated with a process which is able to utilize the fine particle — either a ...


Enefit280 Oil Shale Processing Plant flowsheet. Specifications. As oil shale composition and processing capability is highly dependent on the resource, Outotec, together with our joint venture Enefit Outotec Technology, offers two small-size test facilities. These two units, with 10 and 300 kg/h throughputs, allow testing of the oil ...


crushing, a method that liberates weak oil shale particles from hard limestone waste rock. The first crushing and screening plant with two stage impact crushers was


the crushed rock. The principle of oil shale separation in a crushing bucket is based on the fact that oil shale has smaller compressive strength than limestone. Compressive strength is the main indicator of crushability of a material [[13]]. Compressive strength of oil shale is dependent of surface hardness, cracks and moisture.


the oil shale production process includes mining, oil shale pretreatment, retorting, oil/gas recovery and upgrading, waste treatment and disposal, etc., this paper has taken a systematic approach to quantitative analysis of each step for the whole oil shale pyrolysis process and proposed its resilient


T o use oil shale in production, it is needed to separate oil shale and limestone. A key challenge is A key challenge is find separation process when we can get the best quality for all product ...


water pollution from spent oil shale which should be studied before any significant commercial production is attempted. In Paper II, the proposed Aspen models for oil shale pyrolysis is to identify the key process parameters for the reactor and optimize the rate of production of syncrude from oil shale.The work in Paper IIIfocuses on 1.


Extracting and processing shale oil is an expensive and difficult process. Coal, petroleum, and natural gas are less expensive to extract. Australia, Brazil, …


One consists of mining and crushing oil shale and then transporting the rock to a processing plant. Here, it is heated in special retorts to temperatures of …


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.


The oil shale then will be transferred down from shelf-to-shelf inside the Thermo Processor and heated to temperatures not exceeding 600°C (1110°F). During this process the shale oil will be released in gaseous form and delivered to a condenser, where it will be cooled and finally collected. The spent shale residue will be discharged through ...


FLQ process. Although oil shale has been identifiedas a potential source of liquid fuels because of its abundant reserves, the perfor - mance of oil shale in the world oil market has historically been economically unfavourable because oil shale is con-sidered a low-grade solid fuel that cannot compete with coal as a solid fuel.


The standard process for obtaining oil products from oil shale consists of mining and crushing the shale, retorting the crushed shale to obtain crude shale oil, and refining the oil into usable products. The Bureau of Mines' successful experimental operations have established that …
