Bench-scale and pilot plant experiments were conducted on the ozonization of coke oven gas for the removal of cyanide and thiocyanates. Bubbler reactors with capacities of 0.5 dm/sup 3/ and 1.0 m/sup 3/ were used, and the concentrations of CN/sup -/, CNS/sup -/, and NH/sup +/, as well as the ph were determined. The concentration of ozone entering and leaving the reactor were found and used to compute ozone consumption. This method of cyanide removal compared favorably with respect to cost of reagents used to using sodium hypochlorite.
