A method for separating at least one lower polarity fluid from a mixture of fluids having varying polarity, comprising contacting at least one low polarity or non-polar polymeric membrane with the mixture of fluids under conditions such that the at least one lower polarity fluid selectively permeates through the membrane, wherein the membrane is one which has a ratio of heteroatoms chemically bonded to the carbon atoms in the membrane to the number of carbon atoms of less than about 0.2, preferably less than about 0.05.
L'invention concerne un procédé de séparation d'au moins un fluide à faible polarité d'un mélange de fluides à polarités différentes. Ce procédé consiste à mettre en contact au moins une membrane polymère à faible polarité ou non polaire avec le mélange de fluides dans des conditions telles que le fluide à faible polarité traverse de manière sélective la membrane, celle-ci possédant un rapport d'hétéroatomes chimiquement liés aux atomes de carbone dans la membrane au nombre d'atomes de carbone inférieur à environ 0,2, de préférence, inférieur à environ 0,05.
