Coke dry quenching

Coke Dry Quenching (CDQ) is an alternative to the traditional wet quenching of the coke. Coke is cooled using an inert gas in dry cooling plant, instead of cooling by sprayed water which results in high CO2 emissions and thermal energy loss. This process allows the recovery of the thermal energy in the quenching gas which can then be used for the production of steam and electricity, for district heating, and/or for the preheating of coking coal.
