A real-time mathematical model for the two-dimensional temperature field of petroleum coke calcination in vertical shaft calciner was developed based on computational fluid dynamics. In the modeling process, the petroleum coke discharging process was described by the solid viscous flow, the dynamic heat flux boundary condition was adopted to specify the heat …
Combustion technology of vertical cement kiln. Nowadays, the application technology of high sulfur petroleum coke in shaft kiln cement production line has been mature, not only the quality is stable, but also its exhaust emission has reached the requirements of environmental protection standards. The vertical cement kiln also has its ...
Shaft kiln's small floor space. The vertical kiln is arranged upright. The single-hopper hoist is arranged at a large angle, and the functional areas are compactly arranged to greatly reduce the floor space. Shaft kiln's less investment. The kiln steel structure has fewer machining parts and lower processing costs.
Petroleum coke Anodes Shaft calcining Sulfur Desulfurization Introduction Thermal desulfurization (TDS) of petroleum coke is a well-studied phenomenon and two papers from 2007 and 2008 [1, 2] provide a detailed review including problems TDS creates during calcining and anode baking. A recent paper by Xiao et al. [3], provides an excellent ...

A method of calcining green petroleum coke which includes separating the green coke having a particle size of between 0.1 mm and 50 mm into undersized and oversized fractions, pelletizing the undersized fraction with a binder to form pelletized coke, combining the oversized fraction and the pelletized coke to form a feed mixture, and calcining the feed …
Needle coke, as an important carbon material, can be classified into two types, i.e., petroleum-based needle coke [] with heavy oil as the raw materials, and coal-based needle coke [] with coal tar, coal pitch, or their fractions as the raw materials.Initially, petroleum-based needle coke occupies the dominant position, while the production of coal-based needle coke …
Delayed petroleum coke is calcined in an internally-fired vertical shaft kiln. A downwardly-moving bed of green coke is preheated in the top of the kiln by rising combustion gases, then heat soaked at calcining temperatures in the intermediate section of the kiln, and finally cooled by recycle gas moving upwardly from the lower part of the kiln.
Calcined petroleum coke (CPC) is created from green petroleum coke (GPC), a by-product of refining crude oil. While CPC can be created using a number of processes -- including rotary kiln, hearth and vertical shaft technologies -- the high-temperature conversion from green coke to calcined coke alters the material in key three ways: Drying
