ABSTRACT:
An improved method and apparatus employing at least one immobilized liquid membrane separated from a liquid sweep by a gas-permeable barrier for removing a gaseous component from a gaseous mixture. The improvements include use of one or more liquid-filled passages extending through the gas-permeable barrier to effect diffusive transfer of active carrier species from the liquid sweep into the membrane, thereby maintaining the separation efficiency of each membrane. In a preferred embodiment, the improvements are applied to removal of hydrogen sulfide from mixtures thereof with carbon dioxide as found in gasified coal.
