Bolivia: Processing analysis for oil extraction and flour
A continuous process for treating raw oil shale to produce shale oil of improved quality and yield is described which consists of the following steps: a. crushing and grinding the raw oil shale, b. heating and drying the crushed and ground shale, c. passing the heated and dried shale particles to a slurry mixer where it is mixed with hot heavy oil recycle, d. passing the slurry into a pressurized hydropyrolysis chamber where it is treated with hydrogen under a pressure of 500 to 2000 psi and

Solvent Extraction Method for Edible Oil Processing
Solvent Extraction Process Solvent extraction is achieved through the grinding of seed. The ground seed or cake is then purged or washed with a petroleum distillate (the most common chemical used is hexane) which releases the oil in the seed. The solvent is then “flashed off” by heating the oil in a sealed chamber.
