petroleum coke calcination and not calcination in nigeria
Calcination - WikiMili, The Free Encyclopedia
Petroleum coke, abbreviated coke or petcoke, is a final carbon-rich solid material that derives from oil refining, and is one type of the group of fuels referred to as cokes. Petcoke is the coke that, in particular, derives from a final cracking process—a thermo-based chemical engineering process that splits long chain hydrocarbons of petroleum into shorter chains—that takes place in units
Calcination - Wikipedia
Calcination reactions usually take place at or above the thermal decomposition temperature (for decomposition and volatilization reactions) or the transition temperature (for phase transitions). This temperature is usually defined as the temperature at which the standard Gibbs free energy for a particular calcination reaction is equal to zero.

Petroleum coke is based on heavy oil or other heavy oil after crude oil distillation,pass through the furnace tube of 500 ±1 heating furnace at high flow rate to make the cracking and condensation reaction proceed in the coke tower, and then after the coke is produced after the cooled and decoked to get the petroleum coke.
Method of producing petroleum coke calcinate (Patent) | …
In the calcination of petroleum coke in a rotary kiln, air is controllably supplied internally of the kiln to burn the removed volatiles, as by selection or adjustment of the amount of such air and of the speed of coke travel down the kiln, so that all or nearly all of the heat
Heat Transfer Characteristics of Calcined Petroleum Coke …
In this paper, the calculated model of calcined petroleum coke heat exchanger is equal to the experimental heat exchanger model in scale. Considering the structure characteristic of the heat exchanger, the calculation model is appropriately simplified. (1) The lower ring pipe and the upper ring pipe of the internal heat exchanger and the external heat exchanger will not be calculated.

Optimization of operating conditions in desulfurization of …
During coke calcination, the desulfurization degree depends mainly on the final temperature, the sulfur content, and the chemical structure of sulfur‐containing compounds. Desulfurization of coke breeze is carried out via nonthermal and thermal methods.
Calcined Coke - Aluminium Bahrain
The three main raw materials used by Alba – alumina, petroleum coke and pitch – are unloaded 10km from the main Alba plant at the company’s own marine terminal. Using 65% of the calcined coke we produce to make anodes for the production of our own primary aluminium has earned us wide recognition across the world for the exceptionally high quality of calcined coke.

After calcination, the elemental content of N and O decreased slightly in petroleum coke, while S disappeared in the EDX spectrum of petroleum coke (). Coining the XPS survey spectra and C(1s), O(1s), and S(2p) spectra of green petroleum coke and petroleum coke ( Figure S4 ) as well as the XPS atomic concentration report ( Table S4 ), the S in green petroleum coke was successfully removed.

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 nuer 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:
Experimental study of the coined calcination and …
Green petroleum coke is produced from the heavy residual fractions of petroleum. Petroleum cokes produced from sour crude oil sources contain high quantity of sulfur. A certain level of sulfur is needed to reduce the anode reactivities; however, the demand for anode-grade coke with acceptable sulfur content is increasing faster than the available supply.
