Coke Oven By-Product Plant – IspatGuru

Jan 17, 2014· The coke oven by-product plant is an integral part of the by-product coke making process. During the production of coke by coal carburization in a coke oven battery a large amount gas is generated due to the vaporization of volatile matter in the coal. The gas is generated over most of the coking period, the composition and the rate of ...

Ensuring Efficient Handling of Coal & Coke Products

Coal, coke, and pet coke are all materials that can serve as a fuel source, though each has different origins; coke is most commonly created from bituminous coal, while pet coke (short for petroleum coke) is created as a by-product of the oil refinery "cracking" process.

How a Coke Plant Works - gaspgroup.org

Oct 04, 2018· How a Coke Plant Works. Coal is the main ingredient used to make coke. Iron is produced by inputting coal into a blast furnace. However, coal cannot be put directly into a blast furnace because of all the harmful by-products that come from that. So, there is an intermediate process that occurs. Coal is converted into coke first.

Carbon Dioxide Emission Factors for Coal

In coke plants, coal is carbonized, not combusted, to make coke, which is used in the manufacture of pig iron by the iron and steel industry. Although most of the carbon in the coal carbonized remains in the coke, a small amount is retained in byproducts, some of which are consumed as energy sources and others as non-energy raw materials.

Coke Making Process

Coke is produced by igniting bituminous coal under reduced oxygen conditions in oven batteries specially designed for this process. The coking process generates the following main volatiles as byproducts: coke oven gas, tar, ammonium sulfate, benzol, toluol and naphtha. A coke battery is made up of multiple ovens.
