The role of petroleum coke in steel factoryPetroleum coke (petcoke) plays a significant role in the steel industry, where it is used as a carbon source in the production of steel through the primary steelmaking process. The steel industry uses two main methods of steelmaking: the blast furnace (BF) route and the electric arc furnace (EAF) route. The role of petcoke varies depending on the steelmaking method:Blast Furnace (BF) Route:In the traditional BF route, iron ore, coke, and limestone are fed into a blast furnace, and hot air is blown into the furnace to produce molten iron.

Petroleum coke production processPetroleum coke (petcoke) is a byproduct of the petroleum refining process. It is produced through the thermal cracking of heavy crude oil feedstocks in a process known as coking. The coking process takes place in large, specialized units called cokers. There are two main types of cokers used in petroleum coke production:Delayed Coker: In a delayed coker, the heavy residue from the vacuum distillation unit (also known as vacuum bottoms) is heated in large drums or coke drums.

Advantage to using Calcined Petroleum Coke in prebaked anodeCalcined coke, also known as calcined petroleum coke, is a critical component in the production of aluminum. It is produced by heating raw petroleum coke to remove moisture, volatile matter, and other impurities, resulting in a more concentrated and pure carbon product. The use of calcined coke offers several benefits in the production of aluminum:Improved electrical conductivity: Calcined coke has a high carbon content, which enhances its electrical conductivity.
