Abstract
In an arrangement for removing water vapor from pressurized gases or gas mixtures, particularly from air, a membrane separating apparatus is provided wherein the gas-vapor stream is separated into a vapor-enriched permeate stream and a vapor-depleted retentate stream and the vapor enriched permeate stream is conducted to a vacuum pumping device for generating at the permeate side of the membrane separating apparatus a vacuum providing for a predetermined trans-membrane pressure ratio.
