ABSTRACT:
Disclosed is a process for separating sulfone from a hydrocarbon stream containing a small concentration sulfone by using water as an extraction solvent. The extraction solvent, laden with the removed sulfone, is further processed to separate the extraction solvent and water to thereby produce a sulfone product suitable for reused in an alkylation process or for sale as a dry sulfone end-product.
