ABSTRACT:
An aqueous solution containing from 0.81 to 1.3 moles of piperazine per liter is used as a washing agent for removing impurities such as H.sub.2 S, CO.sub.2 and COS from gases. Piperazine can also be used, in amounts of up to 0.8 mole per liter, together with physical or chemical solvents, to accelerate the absorption of H.sub.2 S, CO.sub.2 and COS. The washing process is used for natural gases, coke-oven gases, gases from the gasification of coal and synthesis gases, of any origin.
