Abstract
An improved membrane pervaporation and vapor permeation system is disclosed in which the vacuum is produced by a fluid passing through a Venturi-type nozzle. The fluid is chosen from solvents that have an affinity for the permeate molecules. It is applicable over of process feed rates, can be used with either organic or aqueous systems and conserves energy relative to existing technology.
