What is Calcining? (with pictures)

Jul 11, 2019· Some recycling facilities use calcination to recycle metal waste products, like grindings, polishing mud, and slurries. It can also be used to turn petroleum coke, a byproduct from oil-distillation that contains a large amount of carbon, into a much purer form of carbon.This calcined petroleum coke can be used for various purposes, such as to make carbon anodes used when producing aluminum.

Petroleum coke - Wikipedia

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

Petroleum coke calcining systems -

Petroleum coke calcining is a three step process, including drying, devolatization and densifiion. The coke calcining process is a time-temperature function, conducted in an oxygen deficient atmosphere. Important control variables are heating rate, air addition rate and final calcination temperature.

Petroleum Coke :: /a>

Product & Process Calcination is a high temperature process for transforming the physical properties of raw petroleum coke. 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.

Impact of Feed Properties and Operating Parameters on

Petroleum Coke General Properties: Volatile Coustible Matter (VCM) • VCM is unconverted pitch – Target 12% Max, fuel coke 9% to 10% – 14% VCM is very high; Coke will be soft • Increases green coke hydrogen content • Rules of thu for control in fuel coke – Increase heater outlet 5-7 °F for 1% decrease in VCM

Modeling and simulation of petroleum coke calcination in

Mass transfer during petroleum coke calcination in rotary kilns is due to transport of water, volatile components and coke particles from the bed to the gas phase, to coustion of coke particles in the bed and in the gas phase, and to coustion of volatiles in the gas phase. 2.3.1.

Calcined Coke

Calcined petroleum coke is the major raw material required for the production of carbon anodes used in the aluminium smelting process. Green coke (raw coke) is the product of the coker unit in a crude oil refinery and must possess sufficiently low metal content in order to be used as anode material.

Calcination - Wikipedia

The IUPAC defines calcination as "heating to high temperatures in air or oxygen". However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.A calciner is a steel cylinder that rotates inside a heated furnace and performs indirect high-temperature
