ABSTRACT:
A process for the separate recovery of oil and asphaltene/polar components from oil and asphaltene/polar bearing sand-containing material includes cooling the material to a temperature at which the material behaves as a solid, crushing the material at such a temperature to produce relatively coarse particles containing a major proportion of the sand and oil and relatively fine particles containing a major proportion of the asphaltenes and polars, and mechanically separating the relatively coarse particles from the relatively fine particles at such a temperature. The relatively coarse particles are treated to recover oil, and the relatively fine particles are treated to recover asphaltenes and polars. Similar processes are desirable for the treatment of heavy crude oil which may or may not contain sand.
