  • Oil extraction process and apparatus therefor
    Patent number: 7002029
    Abstract: A process for solvent extraction of oils, in an extraction chamber, comprises the formation of a solvent mist with significant adiabatic cooling, whereby a pressure difference between the solvent inlet and outlet of the extraction chamber drives the solvent mist through the raw oil bearing. The solvent is fed to the extraction chamber at pressures exceeding atmospheric pressure, and the outlet of the extraction chamber is subject to a partial vacuum. An apparatus for solvent extraction comprises an extraction chamber for receiving oil bearing raw material therein, said extraction chamber comprising a solvent spray injection system connected via an inlet to a high pressure solvent feed circuit portion, said extraction chamber further connected via an outlet to a low pressure circuit portion connected to a gas recovery vacuum pump system.
