The coke oven byproduct plant is an integral part of the byproduct cokemaking process. In the process of converting coal into coke using the byproduct coke oven, the volatile matter in the coal is vaporized and driven off. This volatile matter leaves the coke oven chambers as hot, raw coke oven gas. After leaving the
