Abstract
A process for separating oily films from sand particles carried in a solvent free water stream includes the use of a jet pump scrubber in a density classification tank to treat such oily coated particles at controlled operating temperatures above 65° C. whereby, at such controlled temperature, enhanced cavitation in the jet pump separates the oily film from the sand particles to form slop oil, the tank providing for recirculation of the particles through the jet pump before discharge.
