A process for removing water vapor from water vapor-containing gases is carried out by contacting a feed gas mixture containing water vapor with one side (22) of a semi-permeable membrane (20) selective to the passage of water vapor. A water vapor partial pressure differential is maintained across membrane (20) under conditions such that water vapor selectively permeates through membrane (20) from high pressure side (22) to a lower pressure side (24) of membrane (20). The opposite and lower pressure side (24) is contacted with a dry condensable sweep gas supplied through line (14), which is collected and condensed, thereby causing separation of the sweep gas containing permeated water into an organic liquid phase and an aqueous liquid phase. |
