Process and apparatus for solvent extraction of oil from oil-containing diatomite ore
Patent
·
OSTI ID:6775142
A process is described for solvent extraction of oil-bearing diatomite ore. An apparatus is provided for use therewith, wherein the ore is extracted by countercurrent decantation with a hydrocarbon solvent. The solvent is recovered from the extract by multiple effect evaporation followed by stripping, and the spent diatomite is contacted with water to displace a major portion of the solvent therefrom. The solvent is recovered from the aqueous slurry of the spent diatomite by stripping with steam at superatmospheric pressure. 17 claims.
