FOULING REDUCTION IN SUPERCRITICAL EXTRACTION UNITS

A residual petroleum fraction feed is subjected to a deasphalting process by solvent extraction using a light paraffinic solvent with recovery of the solvent under supercritical process conditions. Fouling is reduced by the injection of an aromatic stream into the DAO-solvent stream from the extract...
