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 1):
A method for purification of natural gas including methane, CO 2 , and C 3+  hydrocarbons, comprising the steps of:\n feeding a feed gas consisting of the natural gas to a first gas separation membrane stage comprising one or more membranes in series or parallel having a selective layer that is selective for C 3+  hydrocarbons over methane; \n withdrawing a first permeate stream from the membrane(s) of the first stage that is enriched in C 3+  hydrocarbons in comparison to the feed gas; \n withdrawing a first retentate stream from the membrane(s) of the first stage that is deficient in C 3+  hydrocarbons in comparison to the feed gas; \n feeding the first retentate stream to a second gas separation membrane stage comprising one or more membranes in series or parallel having a selective layer that is selective for CO 2  over methane; \n withdrawing a second permeate stream from the membrane(s) of the second stage that is enriched in CO 2  in comparison to the feed gas; and \n withdrawing a first retentate stream from the membrane(s) of the first stage that is deficient in CO 2  in comparison to the feed gas.
