This patent describes a process for removing an acid gas component from a gaseous mixture containing the acid gas and hydrocarbons comprising methane, ethane and heavier hydrocarbons. It comprises contacting a feed gas stream comprising the gaseous mixture with an absorbent consisting essentially of an aqueous alkanolamine solution in a contacting zone wherein the acid gas component is absorbed by the absorbent at a temperature in the range of from about 240{degrees} F. to about 260{degrees} F.; withdrawing a liquid stream enriched in the acid gas component from the contacting zone; and withdrawing from the contacting zone a gaseous hydrocarbon stream having a reduced concentration of the acid gas component compared to the concentration of the acid gas component in the feed gas stream.
