Filed: 1975-05-20
Abstract: 1511914 Removing CO 2  from HIS LUMMUS CO 20 May 1975 [11 June 1974] 21587/75 Heading C1A CO 2  is removed from a gas stream containing H 2 S and CO 2  by passing the gas stream through a bed of solid Ca(OH) 2  wherein calcium hydrosulphide and calcium carbonate are initially formed but H 2 S is regenerated from said calcium hydrosulphide by reaction with further CO 2  in the gas. The process is preferably performed at ambient temperatures and the bed may be stripped with steam to recover residual H 2 S. The process is particularly applicable in a heavy water recovery process wherein deuterium is concentrated from a feed water containing CO 2  by absorption and stripping using H 2 S as a circulating medium and the H 2 S absorbs a small quantity of CO 2  along with D in each circulation and thus requires purification.
