Abstract:
A process for separating a component of a first fluid mixture, comprising the following steps:(a) providing a membrane having a feed side and a permeate side, the membrane comprising a separating layer of a polymer having a glass transition temperature, T.sub.g, of at least about 100.degree. C. and a fractional free volume of at least about 0.20, throughout which separating layer are dispersed fine non-porous particles having an average particle diameter no greater than about 1,000 .ANG.;(b) passing the first fluid mixture across the feed side;(c) providing a driving force for transmembrane permeation;(d) withdrawing from the permeate side a second fluid mixture enriched in the component compared with the first fluid mixture.
