发明名称 Membrane process for removing water vapor from gas
摘要 Disclosed is a process for removing water vapor from water vapor-containing gases which is carried out by contacting with a feed gas mixture containing water vapor one side of a semi-permeable membrane selective to the passage of water vapor, maintaining a water vapor partial pressure differential across the membrane under conditions such that water vapor selectively permeates through the membrane from the higher pressure side to the lower pressure side of the membrane, contacting the opposite and lower pressure side of the membrane with a dry condensable sweep gas, and collecting and condensing the sweep gas containing permeated water, thereby causing separation of the sweep gas containing permeated water into an organic liquid phase and aqueous liquid phase.
