Petroleum coke calcination in rotary kilns: material balance …

The process of calcining coke in a rotary kiln is always associated with both inevitable and controlled coke losses. Inevitable losses occur due to both demoisturization and devolatilization, i.e. such losses are a function of the properties of a coke source. Controlled losses are a function of the following: calcination parameters, the condition of the …
