Calcined petroleum coke, produced in a rotary kiln, is used to make anodes for electrochemical furnaces in the aluminium, titanium and steel industries. The normal "green" coke is used as a fuel, where it can be more convenient to use than fuel oil because its properties are sufficiently similar to those of coal that coal/petcoke mixtures can ...
The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the coke. The calcined petroleum coke can be further processed in an anode baking oven to produce anode coke of the desired shape and physical properties. The anodes are mainly used in the aluminium and steel industry.

Simulation of Combustion and Thermalflow Inside a Petroleum Coke Rotary Calcining Kiln A Thesis Submitted to the Graduate Faculty of the University of New Orleans in partial fulfillment of the requirements for the degree of Master of Science in Mechanical Engineering by Zexuan Zhang University of New Orleans, 2003 May, 2007
Calcined coke is the best material for making carbon anodes for smelting of alumina to aluminum. Petroleum coke is usually calcined in a gasfired rotary kiln or rotary hearth at high temperatures, around 1200 to 1450 °C, to remove moisture, drive off volatile matters, increase the density of the coke, increase physical
Oct 18, 2014· The further processing of green coke by calcining in a rotary kiln removes residual volatile hydrocarbons from the coke. The calcined petroleum coke can be further processed in an anode baking ...
A. A Boateng, in Rotary Kilns (Second Edition), 2016. Abstract. Petroleum coke is a byproduct of the coker process in the oil industry. In its raw form, it is also called "green coke" or green petroleum coke. Calcined petroleum coke is an important industrial commodity that links the oil and the metallurgical industries as it provides a source of carbon for various metallurgical ...
Scheme Comparison of Calcination of Petroleum Coke in Retort Calciner and Rotary Kiln. Retort calciner and rotary kiln are the two main types for petroleum coke calcination. Rotary kiln is widely used in Europe and the United States, while retort calciner is used earlier and more in China.
KVS rotary kilns can handle a wide range of green coke feeds including needle, sponge, shot, fluid or tar pitch green cokes. The rotary kiln is also able to optimize the coke calcining operating parameters, be it residence time, temperature gradient, and heat up rate, all .
The oldest and newest petroleum coke calciners employ rotary kilns to thermally upgrade green coke, thus rendering it suitable for use by the amorphous carbon and graphite industries. In response to environmental pressures and rising fuel costs, modern coke calcining facilities are much cleaner and ...
The fuel for this may be gas, oil, pulverized petroleum coke or pulverized coal. Construction. The basic components of a rotary kiln are the shell, the refractory lining, support tyres (riding rings) and rollers, drive gear and internal heat exchangers. History. The rotary kiln was invented in 1873 by Frederick Ransome. Kiln shell

Raw petroleum coke is stored in a closed shed, then transfer to day bins for easy controlling of feed quality and fed into a rotary kiln in controlled ratios. The calcination process raises the material temperatures in the kiln to around 1200 to 1300 deg C depending on the specification of C P Coke required by Customers.
Rotary Kiln The petroleum green coke is fed into a refractory lined rotary kiln where the volatiles are driven off during the calcining process in an oxygen deficient atmosphere. Air can be injected through the kiln shell to burn a portion of the volatile matter in the kiln providing usable heat to the kiln.
After carbonization, the green coke is dried in the Grenzebach plant in a predryer which is heated indirectly using exhaust gases. It then reaches the directly heated rotary kiln. There, it is calcined at temperatures exceeding 1200°C. The calcination process for manufacturing coke is the core of the Grenzebach petroleum coke plant.
He has experience in Rotary Kilns for Calcining Petroleum Coke and has a process design and pending patent for the economical removal of sulfur from the coke. Richard Crisp, BS, Chemistry, University of Alabama, has spent his career in the Coal, Coke and Petroleum Coke Industry.
