Abstract

A process for the separation of liquid component mixtures by combined pervaporation-vapor permeation with a feed flow in the form of a vapor-liquid mixture being employed and the feed flow being passed from bottom to top as a vapor-liquid mixture over a vertically arranged membrane, so that a permanent thorough mixing of vapor and liquid results, and no stationary liquid film is able to form on the surface of the membrane.
