Abstract

PURPOSE: To reduce consumption of alkali for desulfurization and obtain alkali hydrosulfide in a high yield by using alkali sulfide or alkali hydrosulfide contg. a specified range of an effective alkali comoponent as an alkali soln. for washing gas contg. H2S and CO2.
CONSTITUTION: In production of alkali hydrosulfide by alkali-washing acidic gases such as H2S and CO2, acidic gases-contg. cracked gas, fuel gas or exhaust gas generated from an oil refinery, a petrochemical plant, etc., in order to control formation of carbonate due to the CO2 and mixing thereof into the reaction system, a gas washing alkali soln. is prepared by adding caustic alkali and/or alkali sulfide while circulating an alkali hydrosulfide soln. formed in the alkali washing process so that the effective alkali component in the washing alkali soln. is adjusted to 30W 150g/l. Thus, selective absorption of the H2S is promoted.
