Coke Wastewater Treatment: Heating coal over 1100 Co in the absence of oxygen produces metallurgical coke. This process provides both heat and carbon (coke) required for iron production. During this process the volatile materials contained in the coal are driven off, leaving coke as the product. Gas produced by coking is withdrawn by means of blowers to recover energy-rich byproducts, including methane. Ammonia stills are the principal means of recovery. Recycled scrubber water is used as a coolant. Scrubber waste ...
