ABSTRACT:
A process for separating crude oil from a mixture comprising crude oil, finely divided organic solids and water by contacting the mixture with a solvent and a solvent vapor stream in a first contacting zone to heat the mixture and produce a vaporous stream containing at least a major portion of the water and a crude oil laden solvent and inorganic solids mixture which is thereafter separated into a crude oil laden solvent stream and an inorganic solids stream with the inorganic solids stream being thereafter contacted with additional solvent to remove additional quantities of crude oil from the inorganic solids. Crude oil is recovered from a crude oil laden solvent stream.
