ABSTRACT:
A method of separating sulphur compounds out of a gas containing carbon dioxide and hydrogen sulphide, in a gas washing system, said gas being obtained by gasification of spent cellulose liquor. According to the invention the gas washing system has a gas-liquid contact zone (5) operating at a pressure exceeding atmospheric pressure as well as a regeneration zone (8) operating at a pressure substantially less than the pressure in the gas-liquid contact zone (5). The carbon dioxide partial pressure in the gas prior to entering the gas-liquid contact zone exceeds 0.2 atm. Furthermore the gas comes into contact with an alkaline absorption liquid in the gas-liquid contact zone, and alkaline liquid containing alkali hydrogen sulphide is withdrawn from the gas-liquid contact zone and transferred to the regeneration zone, in which zone hydrogen sulphide is expelled from said liquid containing alkali hydrogen sulphide and withdrawn in the form of a gas.
