Carbon electrodes used in the aluminum industry are made from green petroleum coke, which should be calcined to remove moisture and volatile matter, and to acquire an appropriate crystalline structure. This process is carried out in a calcining rotary kiln. A typical kiln for petroleum coke is about 60 m long with a diameter of 2.5 m.
