CA 2406840

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).

L'invention concerne un procédé et un appareil conçus pour déshydrater des huiles. On déshydrate un flux (40) d'huiles contenant de l'eau en le mettant en contact avec un côté d'une membrane (18) sans défaut et imperméable, qui divise une chambre (42) de séparation en un côté alimentation alimenté par ledit flux (40) et une huile déshydratée (44) est évacuée, et un côté perméat à partir duquel l'eau (46) est évacuée. Le côté perméat est maintenu à une pression d'eau partielle basse par dépression ou par utilisation d'un gaz de balayage (50).
