About Petroleum Coke. Petroleum Coke is a solid, carbon-rich material, derived from crude oil refining. More specifically, coke is a bottom of the barrel by-product, result of the end of the cracking process. It is usually distinct in two varieties: fluid coke and flexicoking coke. Fluid coke, or green coke, is obtained from delayed cooking processes. On the other hand, flexicoking is fine grained, with a great level of isotropy. There is also calcinated coke, which is a product of green coke, after above 1300 °C heating. Some Petroleum Coke trades may occur in the spot market, in which the commodity can be purchased for immediate delivery.

The production of Petroleum Coke grew tremendously in the middle of the twentieth century, since petcoke became intensive marketed as a petroleum product in its own right. By country, the United States and China are the largest producers worldwide, followed by South America, Canada, India, Middle East, and Western Europe. Currently, more than 70% of the produced coke is of the green type.

Petroleum Coke Handling. Petroleum Coke in bulk quantities is stored in piles. It is necessary to maintain optimal moisture content and control fugitive dust emissions during storage. This can be done by pile height and compaction control, wetting with water – by water cannons, water trucks, or sprays – and treatment with anti-dust agent.
