Petroleum coke production line

　　 Petroleum Coke Classification and Uses:
　　Petroleum coke is classified into low-ash low-sulfur petroleum coke, medium-sulfur petroleum coke, and high-sulfur petroleum coke according to its sulfur and ash content.
　　According to different refining processes, petroleum coke is divided into: delayed coke, drum coke, fluid coke, and hearth coke.
　　According to different forms, petroleum coke can be divided into four types: needle coke, shot coke or spherical coke, sponge coke, and powder coke.
　　According to the different microscopic structures, petroleum coke can be divided into sponge coke and needle coke. The former is porous and sponge-like, also known as ordinary coke; the latter is dense and fibrous, also known as high-quality coke.
　　High-quality low-sulfur low-ash calcined petroleum coke, such as needle coke, is mainly used to manufacture ultra-high-power graphite electrodes and some special carbon products; in the steelmaking industry, ultra-high-power graphite electrodes are important materials for developing new electric furnace steelmaking technologies.
　　Medium-sulfur, ordinary calcined coke is widely used in aluminum smelting.
　　High-sulfur, ordinary raw coke is used in chemical production, such as the manufacture of calcium carbide and silicon carbide, and is also used as fuel for glass and metal casting.
　 　High-temperature Calcination of Petroleum Coke Technology
　　Combining the chemical industry's considerations of the quality, production safety, yield cost, and investment intensity of calcined petroleum coke, our company adopts the canned calcination furnace technology.

　　The main structures of the canned calcination furnace include: material tank, flue, heat exchanger, charging and discharging device, cooling water circulation device, etc. In the high-temperature calcination process, the heat of combustion of the volatiles discharged from the calcined material is used to calcine the material, thereby achieving energy saving and consumption reduction. Common calcination tanks are divided into co-current calcination and counter-current calcination according to the direction of gas flow and material flow.
