Abstract
A process for bitumen extraction from hydrocarbonaceous solids, such as tar sand or oil shale, is performed in fluidized bed of a swirl reactor. This provides active interaction of three phases: 1) liquid phase—bituminous oil with solvent; 2) solid phase—sand grains, clay; 3) gaseous phase—steam and gasses. The process also involves the step of pressure decrease inside the reactor to activate a gas desorption dissolved in bituminous sand mixture. The process of separation of the bitumen and sand combines centrifuging and discharging individual products for further processing.
