Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units termed coker …
WebApr 11, 2024 · Petroleum coke (petcoke) is a byproduct of the oil refining process. As refineries worldwide seek to operate more efficiently and extract more gasoline and other high value fuels from each barrel of crude oil, a solid carbon material known as petcoke is produced. The physical and chemical characteristics of petcoke are a function of the … WebThus Flexicoking is an integrated coking and gasification process for upgrading heavy feedstocks. This process converts these feeds to a 99% yield of fuel gas, naphtha, middle distillates, heavy gas oil, and a low-sulfur coke gas. The remaining 1% is petroleum coke containing metals and other ash components present in the feed.
