A method and apparatus for the dehydration of oils is shown. A water containing oil stream (40) is dehydrated by contacting stream (40) with one side of a defect-free, nonporous membrane (18). The membrane (18) divides a separation chamber (42) into a feed side into which stream (40) is fed and a dehydrated oil (44) is removed, and a permeate side, from which water (46) is removed. The permeate side is maintained at a low partial pressure of water through the presence of vacuum, or by use of a sweep gas (50).
