Abstract:
Natural gas may be purified by removing C 3+  hydrocarbons and CO 2  in respective first and second gas separation membrane stages to yield conditioned gas lower in C 3+  hydrocarbons and CO 2  in comparison to the un-conditioned natural gas.

Claim (Index 22):
A system for purification of natural gas including methane, CO2, and C 3+  hydrocarbons, comprising:\n a source of natural gas; \n a first gas separation membrane stage comprising one or more membranes fluidly in series or parallel communicating with said source, each membrane of the first gas separation membrane stage having a selective layer that is selective for C 3+  hydrocarbons over methane; and \n a second gas separation membrane stage comprising one or more membranes in series or parallel fluidly communicating with a retentate outlet(s) of the membranes of the first gas separation membrane stage so as to receive retentate from the first gas separation membrane stage as a feed gas in the second gas separation membrane stage, each membrane of the second gas separation membrane stage having a selective layer that is selective for CO 2  over methane.
