Petroleum Coke Single Drum Rotary Dryer
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.
