Abstract:
    The loaded wash liquid contains H2S, CO, H2, CO2, nickel carbonyl and/or iron carbonyl. Carbon monoxide is initially and partially removed from the loaded wash liquid and the wash liquid which is low in CO is conducted through a reaction and settling zone. Sludge containing nickel and/or iron sulfide is extracted from the reaction and settling zone and the wash liquid is conducted to a heat regeneration device. The regenerated wash liquid can be re-utilized for desulfurization purposes.
