Method and apparatus for oil recovery from tar sands
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...

| description | 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. |
