HIGH-PRESSURE SEPARATION OF A MULTI-COMPONENT GAS

摘要

A method of separating one or more components from a multi-component gas stream (10) comprising at least one non-acid gas component and at least one acid gas component, wherein the multi-component gas stream (10), at a pressu re above 1,200 psia (82.8 bar) and a temperature above 120 ~F (48.9 ~C) with a concentration of the at least one acid gas component in gas stream (10) bein g at least 20 mole percent, is passed to a membrane system (40) that selective ly separates the at least one acid gas component from the multi-component gas stream (10) as a permeate stream (13). Permeate stream (13) has a pressure o f at least 20 percent of the pressure of the feed pressure.
