Minor amounts of C3-C4 hydrocarbons from amine absorbents used in removing H2S liquid C3-C4 hydrocarbon are recovered. The process features recovery of the C3-C4 hydrocarbon in a hydrocarbon gas from a second absorption zone where H2S is removed from the hydrocarbon gas, the hydrocarbon gas functioning as a stripping gas. |
