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.

A process for separation of fluid mixtures by means of a combined pervaporation-vapor permeation process comprising:
- passing a feed flow over a vertically arranged membrane from bottom to top as a vapor-liquid mixture, 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;
- and
- recovering a component of the feed flow in a permeate flow on an opposite side of the membrane from said feed flow.
A process for separation of fluid mixtures by means of a combined pervaporation-vapor permeation process comprising:
- separating the feed flow into a vapor portion and a liquid portion and passing the portions through separate lines into a module containing a membrane;
- passing the vapor portion and the liquid portion of the feed flow over a vertically arranged membrane from bottom to top as a vapor-liquid mixture, 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;
- and
- recovering a component of the feed flow in a permeate flow on an opposite side of the membrane from said feed flow.
