The paper discusses the formation of cyanides in coke oven gas and describes and compares waste processing options. These include desulfurization by aqueous ammonia solution, desulfurization using potash solution, desulfurization in oxide boxes, decomposition of NH{sub 3} and HCN for gas scrubbing. Waste water treatment methods include chemical oxidation, precipitation, ion exchange, reverse osmosis, and biological treatment. It is concluded that biological treatment is the most economical process, safe in operation and requires a minimum of manpower.
