Abstract
Methods for removing acidic gases from gaseous mixtures, such as hydrocarbon containing gaseous mixtures, are disclosed. The method includes washing the gaseous mixtures with a methanol wash stream containing more than about 0.5 weight percent ammonia therein, so as to remove at least a portion of the acidic gases from the gaseous mixtures and to produce a laden methanol stream containing said acidic gases therein, regenerating said laden methanol stream by removing a portion of said acidic gases therefrom, so as to regenerate said wash stream, and recycling the regenerated wash stream.
