Coke Dry Quenching Technology: Review and Case Study of First CDQ Project in Iran

The purpose of this article is to review the best technologies used in the hot coke quenchingprocess while focusing on Coke Dry Quenching (CDQ) technology which uses inert gas insteadof water (thus the term dry to cool down the hot coke. After brief history and generalintroductions, parameters for choosing the best technology are illustrated. As we go into details,CDQ process is explained step by step starting from hot coke production in the oven (temperaturearound 1000±50˚C) until delivery of cold coke (temperature below 200˚C) along withspecification and function of main equipment, and also achievable side-processes of CDQ such asgenerating electrical power from the heated gas. Finally, experiences gained by GMI fromestablishing the first CDQ plant in Iran are represented.
