Coke-calcining plants receive green petroleum coke from oil refineries. The green coke is blended and fed into rotary kilns operating up to 2800°F under a reducing condition. The material exits the rotary kiln as calcined coke with a correct crystalline structure and electrical conductivity properties.
The process of calcination derives its name from the Latin calcinare (to burn lime) due to its most common application, the decomposition of calcium carbonate to calcium oxide and carbon dioxide, in order to create cement.The product of calcination is usually referred to in general as "calcine", regardless of the actual minerals undergoing thermal treatment.
