ABSTRACT:
The removal of water vapor from a gas/vapor mixture by means of vapor permeation takes place by passing the mixture to be separated along one side of a membrane and the permeation of water vapor through the membrane is achieved by maintaining a relatively low partial pressure of water vapor on the other side of the membrane. To increase the flux the membrane is impregnated beforehand with a hygroscopic electrolyte.
