Abstract:
A method of separating one or more components from a multi-component gas stream comprising at least one non-acid gas component and at least one acid gas component, the method comprising:(a) providing a multi-component gas stream at a pressure above 1,200 psia (82.8 bar) and a temperature above 120Â° F. (48.9Â° C.) with the concentration of at least one acid gas component in the gas stream being at least 20 mole percent; and (b) passing said multi-component gas stream to a membrane system that selectively separates at least one acid gas component from the multi-component gas stream as a permeate stream, said permeate stream having a pressure at least 20% of the pressure of the feed pressure.
