Petroleum coke, or petcoke, is a product produced from all types of oil (light/heavy crudes) during the oil refining process. Many different products are extracted from a barrel of crude oil in addition to gasoline, diesel and jet fuels. Petroleum coke just one of the many. Petroleum coke is not a new product and has been produced since the 1930s.
Petroleum coke is a process that involves steps such as thermal decomposition, polymerizationion and condensation. The Petroleum Coke category consists of two substances; green coke and calcined coke. These two substances are grouped together in a category based on their similarity of manufacturing processes which

Basic calcining process. 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.
The refinery has a processing capacity of approximately 55,000 barrels (2.3 million gallons) of crude oil per day. Refining crude oil into transportation fuels and other products is a complex process involving many steps. The key steps include: Separation: Crude oil is separated into different parts based on the size of the molecules.
