Abstract
1428622 Removing acid gases STONE & WEBSTER ENG CORP 6 March 1974 8748/74 Heading C5E In the process for removing acid gases from gaseous hydrocarbons wherein the gaseous hydrocarbons are contacted in an absorption zone with a lean aqueous amine absorption solution to remove the acid gases therefrom thus forming a rich aqueous amine solution, which rich aqueous amine solution contains C 4 and heavier unsaturated hydrocarbons as a result of contacting the lean aqueous amine solution and the gaseous hydrocarbon in the absorption zone; and, wherein the rich aqueous amine solution is regenerated by amine stripping to become lean aqueous amine solution, the improvement comprising: delivering the rich aqueous amine solution from the absorption zone to a rich amine prestripping zone; delivering a low molecular weight noncondensable gas stripping medium to a rich amine prestripping zone; passing the low molecular weight non- condensable gas stripping medium and the rich aqueous amine solution through the prestripper in countercurrent flow; removing from the prestripping zone, the low molecular weight noncondensable gas stripping medium with the C 4 and heavier unsaturated hydrocarbons stripped from the rich aqueous amine solution; and delivering the rich aqueous amine solution which has been prestripped of C 4 and heavier unsaturated hydrocarbons to the amine stripping equipment. The process is particularly applicable to the removal of CO 2 and H 2 S from olefins produced by hydrocarbon pyrolysis.
