Traditionally dry quenching process is being adopted for the cooling of Coke produced from the Coke Oven Battery in Steel Plants. Water is used as cooling media to cool the hot coke which not only consumes large volume of water but also releases harmful pollutants which is also not permitted buy the government latest regulations. Also the hot gas generated from the quenching process is released to atmosphere without any commercial use.

Coke Dry Cooling Plant is a clean technology that uses gas instead of water in an enclosed system to cool the hot coke. The hot gas can be recycled to create electricity. As a result, money is saved from conserving electricity and pollution is reduced from lower emission of CO₂ and other pollutants.
