Petroleum coke is the vacuum residue of petroleum, which is produced by cracking and coking at 500-550 °C in a coking unit. Petroleum coke is a product obtained by the process of separating light and heavy oil from crude oil by distillation, and then the heavy oil is thermally cracked. Glossy, the coke particles have a porous structure, and it is generally considered to be an amorphous carbon body, or a black solid coke with a needle-like or granular structure containing tiny graphite crystals in a highly aromatized polymer carbide. The main element composition is carbon, accounting for more than 80%, hydrogen 1.5%-8%, and the rest are oxygen, nitrogen, sulfur and metal elements. The carbon-hydrogen ratio is 18-24, the relative density is 0.9-1.1, the ash content is 0.1%-1.2%, and the volatile matter is 3%-16%. Calcined petroleum coke can be divided into green coke and cooked coke according to the processing method. Green coke is obtained from the coke drum of the delayed coking unit, also known as primary coke, which contains more volatile substances and has poor strength. Cooked coke is obtained by calcining green coke at 1300°C, also called calcined coke. Calcined petroleum coke is a partially graphitized form of carbon. Widely used in metallurgy, chemical industry and other industries as electrodes or raw materials for the production of chemical products.
The moisture content of petroleum coke is 12-15% after pyrolysis and calcination at high temperature, wet coke quenching and cooling process. Before grinding and pulverizing, the moisture must be dried to less than 3%. Zhengzhou Jiutian Machinery is fortunate to undertake a number of domestic petroleum coke drying projects. The project has won high praise in the industry and is well-known in the petroleum coke drying market by virtue of its advanced technical concepts, perfect comprehensive support capabilities, high-efficiency, energy-saving and environmentally friendly equipment and after-sales service.
Materials:Suitable for petroleum coke, etc.
Application:Drying petroleum coke for fuel preparation and industrial use.
Petroleum coke is conveyed by belt conveyor or bucket elevator to the hopper, then fed into the rotary dryer. The slightly inclined drum allows material to enter from the higher end, while hot air or flue gas enters from the lower end, forming countercurrent heat exchange (or co-current if required).
As the drum rotates, the material moves forward by gravity. Internal lifting plates continuously raise and disperse the petroleum coke, increasing contact with the hot gas to improve drying efficiency. The dried product is discharged by belt or screw conveyor.
Exhaust gas passes through a cyclone dust collector, and if lower emissions are required, through a bag filter or wet scrubber before final discharge.
