Prevention of membrane degradation. |
摘要 |
<p>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.</p> |
