Petroleum Coke. Petroleum coke is a carbonaceous product obtained in the oil refining process. It is abbreviated as Coke or Petcoke, and is a carbon-rich solid material derived from final cracking process — a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains— that takes place in coker units.

The use of petroleum coke may be limited by its high sulfur content. Technological measures such as finer grinding, pre-calciners designed to have a higher retention time, an external combustion chamber before the calciner, a special high-momentum kiln burner, etc. will help to effectively utilize Petroleum coke.

The CPCB study of M/S JSW Steel indicates that only two per cent of the sulphur content in the coal blend is liberated as hydrogen sulphide (H 2 S) and is emitted along with the coke oven gas in a recovery-type oven (Indian Steel Association 2019). While 67 per cent of the sulphur is absorbed by the coke, another 31 per cent is retained in sludge and tar.
