H2S Gas Exclusion Method and The Apparatus of Coke Oven Gas

摘要

The present invention is a coke oven gas: Treat the absorber concentrated waste solution, in particular, a coke oven gas concentration absorption of hydrogen sulfide and hydrogen cyanide and ammonia gas was in the relates to a desulfurizing method and apparatus of (COG Coke Oven Gas), and finally desulfurization method capable of coke oven gas produced in the crystallization of ammonium sulfate and an object thereof is to provide the device.; Desulfurization process of the coke oven gas according to the present invention having the above object, the method for concentrating a high-concentration aqueous solution of ammonia in an ammonia gas absorption tower 20, and the step of concentration of high density ammonium sulfide solution in the hydrogen sulfide absorption tower (10) the step of preparing the ammonium sulfite solution from a gas generator 30, high-concentration hydrogen sulfide, and; and SOx gas absorber 50 for the step of cyanide generate hydrogen gas, generating a cargo gas sulfuric acid in the combustion furnace 40 in the and, to the oxidation tower 60, characterized in that made in a step of producing the ammonium sulfate crystallization step and ammonium sulfate production plant 70 for producing the aqueous ammonium persulfate solution.
