Abstract
A process for recovery of sulfolane used in a solvent-extraction or extractive-distillation process includes introducing a mixture into a solvent-recovery column having a heat source connected to a bottom portion of the column and removing a lean solvent stream, substantially free of hydrocarbons, from the bottom of the column, removing a polar-hydrocarbon-rich overhead stream from the top section of the column and maintaining the needed vacuum conditions using a liquid-jet ejector, preferably using water as the liquid.
