A process is provided for removing polymeric fouling on process equipment surfaces to restore the efficiency of such equipment. This is accomplished by contacting the fouled equipment with a solvent comprising at least one non-aromatic hydrocarbon compound, or a mixture of one or more non-aromatic organic compounds and one or more aromatic hydrocarbon compounds, for a period of time sufficient to remove the polymeric fouling.

Process for removing polymeric fouling

A process is described for removing olefinic polymer mass buildup fouling process equipment to restore the efficiency of such equipment. This is accomplished by circulating through the equipment in contact with the polymer an aromatic hydrocarbon solvent having a high boiling point and low vapor pressure for a period of time sufficient to remove the polymer. The solvent is recovered for reuse by a flash separation from the removed olefinic polymer mass.
