The invention describes a graded crushing and screening system and a method for crude oil shale ores, wherein the graded crushing and screening system comprises: a storage bin; the primary crusher is communicated to a discharge port of the storage bin and is constructed to crush the oil shale raw ore to the granularity of-300 mm; the secondary …
The crushing process involves the use of crushers to break down rocks and stones into smaller sizes. The primary crusher is used to reduce the size of the initial rocks, while the secondary crusher further …
Oil shale is a sedimentary rock. As it reaches its oil window, oil shale releases a liquid known as shale oil. Oil shale is the rock from which shale oil is extracted. Shale oil is similar to petroleum, and can be refined into many different substances, including diesel fuel, gasoline, and liquid petroleum gas ( LPG ).
Estimates of global deposits range from 2.8 to 3.3 trillion barrels (450×109 to 520×109 m3) of recoverable oil shale in place. Heating oil shale to a sufficiently high temperature causes the ...
Oil shale resources are typically expressed in either of two different ways: (1) as tons of oil shale and (2) as crude shale oil equivalents contained in the oil shale. Global deposits have been estimated to be about 411 metric gigatons or to range from 2.8 to 3.3 trillion barrels (4.5 × 10 11 to 5.2 × 10 11 m 3 ) of recoverable oil ...
The purposes of these studies were to develop crushing cost levels for crushing plants utilizing different types of crushers, to determine the effect of final
In order to better understand oil shale pyrolysis process, some mathematical models on oil shale particle pyrolysis were developed in last decades. Granoff et al. [27] developed a non-isothermal shrinking-core model considering the kinetics of oil shale pyrolysis and heat transfer effects, which could describe the observed pyrolysis process
Froth quality is a very important performance metric for any oil sands Extraction plant. There are 3 components found in bitumen froth: (1) bitumen, (2) fine solids and (3) water. 1. Bitumen Grade: Froth quality is measured by the bitumen grade (or content) of the froth. A froth containing 55-60% bitumen is considered good quality.
crushers for oil shale - I-Valor. primary crushing of oil shale size - danceout The Impact of Oil Shale Calorific Value on CFB Boiler pdf The median sizes of the oil shales fed into boiler R [0.5] were 0.48 mm and 0.56 mm. The reason for the finer upgraded oil shale can be found in the better operating conditions of the primary crusher. More
Oil shale - Surface Processing, Retorting, Pyrolysis: Four basic steps are involved in the aboveground processing of oil shale: mining the ore (either through underground or surface mining), crushing the ore to a size that can be handled by the retort, retorting (heating) the crushed shale to pyrolysis temperatures, and upgrading the oil obtained by …
Oil shale resources are typically expressed in either of two different ways: (1) as tons of oil shale, and (2) as crude-shale-oil equivalents contained in the oil shale.
