Hydrogen sulfide is removed from a mixture of gases including carbon dioxide by passing the mixture over an immobilized liquid membrane in intimate contact with a hydrophobic, microporous gas, permeable barrier and absorbing in a liquid solution hydrogen sulfide passing through the membrane. In a sweep of hot carbonate solution, a nearly stagnant boundary layer adjacent the gas permeable barrier absorbs acid gases by reaction and diffusion, maintaining low hydrogen sulfide partial pressure at the outlet side of the barrier. Alternatively, the sweep may c...


A method of selectively removing hydrogen sulfide from a mixture of gases including carbon dioxide, comprising: contacting an immobilized liquid membrane with said mixture to allow facilitated transport of hydrogen sulfide through said membrane to a porous gas-permeable barrier; passing gases emerging from said membrane through said gas-permeable barrier; absorbing in a sweep liquid the gases emerging from said gas-permeable barrier; and said sweep liquid comprising a liquid selected from a group consisting of a hot carbonate solution, a solution of redo...
