A process for selectively separating water vapor from a multiple component gaseous mixture is provided. The process comprises passing a multicomponent gaseous mixture including water vapor along and in contact with a membrane which is selectively permeable to water vapor and wherein the water vapor permeation rate QH2O is greater than 30 Nm3/m2ㆍhrㆍatm at 25°C. and the ratio of QH2O to the permeation rate QG of the gas to be separated from the water vapor, i.e., QH2OQG, is greater than 10,000. The membrane preferably has a thickness of about 0.1 microns to about 50 microns.
