The present invention provides a method for separating conjunct polymers which are formed as byproducts of acid catalyzed isoparaffin-olefin alkylation and sulfolane from a mixture containing conjunct polymers, sulfolane, and hydrofluoric acid, which method provides a sulfolane recycle stream which requires no further drying before charging the stream to the alkylation reaction zone. |
