The vacuum residue of petroleum is produced by cracking and coking at 500-550 °C in a coking unit. Petroleum coke (Petroleum coke) is a product that is converted from crude oil to light and heavy oil after distillation and the thermal cracking of heavy oil. From the appearance, coke is a black block with irregular shapes and different sizes. , with a metallic luster, the coke particles have a porous structure, it is generally considered to be an amorphous carbon body or a black solid with a needle-like or granular structure containing tiny graphite crystals in a highly aromatized polymer carbide. coke. 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℃, 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 Dingli New Energy Equipment Co., Ltd. has the honor to undertake a number of domestic petroleum coke drying projects. The project has won praise in the industry for its advanced technical concepts, perfect comprehensive support capabilities, high efficiency, energy-saving, and environmentally-friendly equipment and after-sales service, and is well-known in the petroleum coke drying industry. market.
1. Petroleum coke dryers mostly use multi-layer tumble dryer structure, which has a small footprint and large processing capacity;
2. The environmentally friendly petroleum coke dryer has diversified heat sources, and clean fuels such as natural gas, coke oven gas, and oil fuel replace coal to reduce the pollution of hot blast stoves;
3. The dust collector system is flexibly configured according to the form of heat source, the dust collector is low in cost, and the dust removal efficiency is high, which promotes the environmental assessment of the petroleum coke drying project
4. Petroleum coke dryer manufacturer customized production, daily output is not limited, free installation and commissioning, and the project is put into production quickly.
