ABSTRACT:
Minor amounts of C.sub.3 -C.sub.4 hydrocarbons from amine absorbents used in removing H.sub.2 S liquid C.sub.3 -C.sub.4 hydrocarbon are recovered. The process features recovery of the C.sub.3 -C.sub.4 hydrocarbon in a hydrocarbon gas from a second absorption zone where H.sub.2 S is removed from the hydrocarbon gas, the hydrocarbon gas functioning as a stripping gas.
