摘要

1. A washing solution for removing acid gas components from industrial gases, the gas stream being brought into contact with a liquid absorber in a suitable wet cleaning device, characterized in that the liquid absorber is an aqueous solution containing ammonia and at least one amine, and the amine molecule does not contain hydroxyalkyl substituents. 2. A washing solution according to claim 1, characterized in that the amine is a primary or secondary amine. A washing solution for removing acid gas components according to claim 2, characterized in that the primary amine has the general formula: HN-R, where R is selected from alkyl groups, aryl groups or arylalkyl groups. A washing solution for removing acid gas components according to claim 2, characterized in that the secondary amine has the general formula: R-N (H) -R, where R and R are independently selected from alkyl groups, aryl groups or arylalkyl groups. A washing solution according to claim 4, characterized in that the secondary amine is selected from diethylamine, dipropylamine or diphenylamine. A washing solution for removing acid gas components according to claim 2, characterized in that the amine has the general formula: RR-NXN-RR, where R, R, R and R are independently selected from alkyl groups, aryl groups or arylalkyl groups, and X represents an alkylene or arylalkylene group. 7. A washing solution according to claim 1, characterized in that the amine is selected from five-membered or six-membered saturated heterocyclic compounds containing at least one NH group in the ring. A washing solution according to claim 7, characterized in that the amine is selected from piperazine or a piperazine derivative. Wash solution according to any one of claims 1 to 8,
