ABSTRACT:
A method and apparatus for removing hydrogen sulfide from crude coke oven gas comprises initially scrubbing the crude coke oven gas in a low pressure scrubber using an aqueous regeneratable liquor. The gas is subsequently scrubbed in a high pressure scrubber using the same liquor. Streams of spent washing liquor are united and supplied to a regenerating unit where the hydrogen sulfide is removed in the form of sulfur or sulfuric acid. After the regenerating unit the liquor is returned to the high and low pressure scrubbers.
