Abstract

A process for eliminating waste liquors accumulated in the desulfurization of coke oven gas with a washing solution containing an organic oxygen carrier includes evaporating between 30 and 70% of the water from the waste liquor to provide a concentrated waste liquor solution. The concentrated waste liquor is introduced into a combustion chamber with air and coke oven gas. The concentrated waste liquor is thermally decomposed in the combustion chamber and eliminated sulfur is separated from the gaseous products of combustion. The gaseous products of combustion are admixed with the coke oven gas evolved during the coking process.
