ABSTRACT:
Disclosed is a process for separating sulfone and hydrogen fluoride from hydrocarbon streams containing a concentration of such compounds. An extraction solvent laden with sulfone and HF is contacted with a reversible base in order to remove the HF therefrom. The thus-treated extract stream is separated into a water stream that can be reused as the water extractant and a sulfone stream that is suitably free of HF.
