Abstract
PURPOSE: To obtain cuprous thiocyanate in a high yield by decoloring desulfurization waste liquor, with activated carbon, discharged from a coke oven gas wet desulfurization process and adding divalent copper salt in amts. equimolar with thiosulfuric acid in the decolored liquor to equimolar with thiocyanic acid.
CONSTITUTION: Waste liquor discharged from a coke oven gas wet desulfurization process is decolored with activated carbon, and on the supposition that thiosulfuric acid in the decolored waste liquor is T mol, sulfite to be added to the liquor Sa mol, thiosulfuric acid to be added to the liquor Ta mol and divalent copper salt C mole, the above-mentioned two cpds. are added to the liquor so as to satisfy thiosulfate and divalent copper salt (CuSO4 or the like) of equations I, II. Thus, thiocyanate and thiosulfuric acid in the liquor are effectively utilized, and cuprous thiocyanate can be synthesized cheaply only by supplying the shortage. The load of activated sludge treatment or other treatment of the liquor is reduced. In place of the thiosulfuric acid sulfurous acid may be used.
