Abstract
"CO2 ADDITION TO SUPPRESS H2S EVOLUTION IN ABSORPTION-DESORPTION PROCESS" Abstract of the Disclosure In the methanol scrubbing of sour gases, especially CO2 and H2S, from gaseous mixtures wherein the methanol contains alkaline-reacting compounds to counteract corro-sion and is regenerated for reuse by expansion, stripping and/or thermal regeneration, CO2 is introduced into the methanol circuit at a location where the latter is usually free of CO2, e.g., at the bottom of a thermal regeneration column, in order to suppress the formation of sulfide com-pounds, e.g., NH4HS, capable of decomposing into H2S upon contact with CO2 at the top of the scrubbing column.
