Any SO 2 present in the flue gas will be removed utilizing a chemical reaction with sodium carbonate (soda ash). The soda ash is automatically added to the scrubbing water through pH control. After cooling and scrubbing, the gas is led via an exhauster through an absorber, in which the gas flows countercurrent to the MEA solution flow.

The flow of coke oven gas is withdrawn from the battery by a centrifugal blower, the exhauster, and delivered through the gas vessels of the byproduct plant at a sufficient pressure for distribution as a fuel. Before passing to the exhauster, the gas is cooled in the primary gas coolers to around 25 deg C.

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

How coal is formed. Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.
