摘要：
An improved, membrane-based method of treating gas evolved during natural gas liquids (NGL) stabilization, to separate the very light hydrocarbon gases, methane in particular, from the heavier hydrocarbons. The membrane acts as a demethanizer and establishes a vapor/liquid equilibrium during phase separation that is different than would otherwise obtain. This can increase NGL production and reduce the weight of C.sub.3+ hydrocarbons in the off-gas from the stabilizing phase separators.
