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 applications including the manufacture of anodes for the aluminum pot liners and for graphite electrodes. Most of the calcining of petroleum coke is carried out in rotary kilns.
Application of Environmental Calcined petroleum coke rotary kiln Rotary kiln is thermal equipment to heat materials. The raw material to be processed is fed into the upper end of the cylinder. The finished limesone can used as building and industry raw material,and can also be processed into white lime.

usually calcined in a gas fired 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
Once the calcined coke is discharged from the kiln, the coke is cooled in a rotary cooler. At the feed end of the cooler, water is sprayed on the calcined coke to cool the coke to acceptable temperatures. The water is evaporated in the process. Afterburner The kiln exhaust gas is oxygen deficient and contains volatile matter released in the kiln.
Petroleum coke (petcoke) is a black colored solid composed primarily of carbon, and may contain limited amounts of elemental forms of sulfur, metals and non volatile inorganic compounds.
Pet Coke For Rotary Lime Kiln sirptscience. Calcining of petroleum coke is done in the rotary kiln. The kiln components consist of shell, tires, carrying stations, seals, refractory and a

The same coke calcined in a rotary kiln might yield a mercury density of 1.73 1.77g/cc depending on how it is calcined. The differences in density between shaft calcined coke and rotary
3 It has to be remembered, that the green coke input in a shaft kiln is much finer than that for a rotary kiln. In spite of this the produced calcined coke is
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.
Tutorial Petroleum Coke Calcining and Uses of Calcined Petroleum Coke the kiln in 40 to 60 minutes and drops off the discharge end of the kiln into a refractorylined chute and into a rotary cooler.
Raw Coke after Calcination is known as Calcined Petroleum Coke. At India Carbon, Calcination is performed in an oil fired rotary kiln with suitable refractories. Raw Coke crushed into lumps is fed through Conveyor System to the slightly elevated end of the rotary kiln.
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 in order to produce anode coke of the desired shape and physical properties.

Calcined Petroleum Coke is a critical ingredient in the production of aluminum. It is created by placing high quality raw 'green' petroleum coke into rotary kilns, where it is heated to temperatures between 1200 to 1350 degrees C (2192 to 2460 F).
Coke calcining occurs in a horizontal, counter current, gas fire d rotary kiln. Th e kiln is arrange with th raw cok feed hood near the flue gas discharge and the calcined coke discharge located at the firing hood. Calcined coke is air cooled in two horizontal, rotary kilns which also serve as the calciner air preheater.
