Abstract
PURPOSE: To greatly lengthen the life of a catalyst layer by a method in which in the removal of offensively odorous components by both an activated carbon catalyst and ozone, the activated carbon catalyst layer is divided into a catalyst layer for general deodorization and a catalyst layer for removing methyl sulfide and also ozone is added before each catalyst layer.
CONSTITUTION: An offensively odorous gas containing methyl sulfide is passed through a mist separator 1 and a dedusting filter 2 to remove fine liquid droplets and dust. Then, ozone from an ozonizer 3 is added to the gas and then the gas is passed through the first-stage activated carbon catalyst layer 4 to remove hydrogen sulfide, methyl mercaptan, methyl disulfide, ammonia, trimethylamine, and hydrocarbons by adsorption, by means of the concentration of diluted gas and the oxidizing action of ozone. Then, ozone is again added to the treated gas containing residual methyl sulfide and the treated gas is passed through the second-stage activated carbon catalyst layer 5 packed with activated carbon whose adsorptive surfaces are given active groups, e.g., halogen, etc., to remove methyl sulfide by adsorption. Thus, the treated gas can be completely deodorized.
