ABSTRACT:
A method for separating conjunct polymers and sulfolane from a mixture containing conjunct polymers, sulfolane, and hydrofluoric acid is disclosed, which method comprises the sequential steps of separating hydrofluoric acid from said mixture to provide an intermediate stream containing less than about 30 percent hydrofluoric acid by weight and gravitationally separating said intermediate stream into a sulfolane-enriched stream and a conjunct polymer-enriched stream.
