초록

In the separation of gases in a membrane system, degradation of membrane permeability is prevented by passing the feed gas mixture through a bed of adsorbent material, preferably activated carbon, to adsorb the heavier hydrocarbon contaminants responsible for degradation without removal of lighter hydrocarbons.

대표
청구항

In a process for the separation of a feed gas mixture in a membrane system capable of selectively permeating a more readily permeable component of said feed gas mixture containing said component and a less readily permeable component, in which said feed gas mixture contains contaminants comprising hydrocarbons heavier than C5 (pentane) and lighter hydrocarbons of C5 or less, the improvement consisting essentially of: (a) contacting the feed gas mixture containing said contaminants with a bed of adsorbent material prior to passage to said membrane system,...
