Petroleum Coke Calcining Systems Outotec

Petroleum coke calcining is a three step process, including drying, devolatization and densification. The coke calcining process is a time-temperature function, conducted in an oxygen deficient atmosphere. Important control variables are heating rate, air addition rate and final calcination temperature. To obtain the calcined coke properties required by the carbon and
