ABSTRACT:
An improved, membrane-based method of treating gas evolved during gas/oil separation, 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 oil production and reduce the weight of C.sub.4+ hydrocarbons lost in the associated gas.
