  • Process for separating oil from a naturally occurring mixture
    Patent number: 4344839
    Abstract: A process for separating hydrocarbons from naturally occurring mixtures comprising minerals and inorganic materials originating from rock admixed with oil, for example tar sands and oil shales. The process comprises introducing particles of such mixtures into a gaseous plasma of a chemically inert gas to vaporize the hydrocarbons and thus separate them from the solid particles. The solid particles are allowed to drop from the plasma. The vaporized oil is condensed as a separate stock.
