Abstract

The present invention comprises a process and apparatus for recovery of sulfolane used in a solvent-extraction or extractive-distillation process. A recovery column for the sulfolane solvent comprises a liquid-jet ejector for maintaining the needed vacuum conditions, preferably using water as the liquid.
