Tenova's rotary hearth petroleum coke calciners can process both anode grades and needle cokes. The rotary hearth calciner uses the volatiles from the coke to combust and produce heat for the processing of the coke. In many cases, not external heat or fuel is required during operation.
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 …
The article deals with the main problems of a modern industrial technology for producing calcinated petroleum coke from green coke in a tubular rotary kiln. A high quality calcinated coke is obviously necessary both for metallurgy and chemical industry, hence its properties should meet the corresponding high requirements. Petroleum coke is a nice
Typical temperatures for a rotary coke calcining kiln are between 2200°F (1200°C) and 2400°F (1315°C). Alumina-silica refractories in the 40% to 70% Al2O3 range are appropriate for these normal operating temperatures. Petroleum coke calcining operators prefer single-layer brick linings using rotary kiln block (RKB's).
Coke from petroleum ("petcoke") is entirely analogous. Its importance has risen as oil has supplanted coal as an energy source, and as the rising price of crude oil has demanded a higher recovery of high-value fractions from the raw material.
Rotary calciners (sometimes referred to as rotary kilns) are used for a variety of material processing applications. These high temperature machines process materials into a desired form by changing the state or …
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 …

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 coke progresses towards the firing end of the kiln and during it's ...
PETROLEUM COKE - EFFECTS ON REFRACTORY INTRODUCTION In the recent past, Petroleum Coke has been used to supplement the primary fuel source (coal) in most North American cement manufacturing facilities. Within the last few years a number of plants have progressed from burning a low percentage of Coke (10-25%) to Coke and other …

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 …
Green petroleum coke is generated by delayed distillation of coal during the conversion of crude oil into liquid fuels such as gasoline and jet fuels. Calcined petroleum coke is produced from green petroleum coke …
The calcined petroleum coke usually discharged into a rotary cooler. SENECA 60 P or PATRIOT rotary kiln block can be utilized for the cooler lining. In some cases where it is desirable to anchor the refractory lining to the rotary cooler shell, low-cement high alumina castables, like QUIKTURN 60 PC and R-MAX PC QT, give excellent service.
Petroleum coke has been studied extensively, and periodically employed, as an additive for the manufacture of metallurgical coke for the steel industry [51, 52]. This practice, ongoing for several decades, typically mixes 5% to 40% (weight basis) petroleum coke with coal in the coking ovens.
plants consume fuel-grade petcoke in rotary kilns. Anode grade calcined petcoke is the principal raw material used in manufacturing carbon anodes for use in aluminum smelting. The anodes act as conductors of electricity and as a source of ... Petroleum Coke: Industry and Environmental Issues . Petroleum Coke: ...
Rotary Kiln Petroleum Coke Calcination Process Authors: Akwasi A. Boateng United States Department of Agriculture Abstract Petroleum coke is a by …
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 for calcining the coke is provided by such combustion, and so that a suitably …
Calcined petroleum coke is mainly used to produce anodes used in the aluminum industry, steel making and titanium dioxide industries among other niche applications. The coke calcining process is a time …
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.
Petroleum cokes are usually obtained from highly aromatic catcracked secondary gas oils or gas oil residues and heavy pyrolysis residues in a semibatch mode in special large reactors. Then "green" petroleum coke is calcinated at high temperatures (over 1000°C) in tube kilns, electric calcinators, or retort furnaces.
Calcined Petroleum Coke. 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 …
Rotary kilns are widely used by industry to carry out a wide variety of material processing applications, including calcination of limestone, petroleum coke calcination, ore reduction, and reclamation of hydrated lime and contaminated soils. The reason for the wide-spread usage is the ability to handle varied feedstock,
Also known as Petcoke or coke, it is a carbon (C) – rich solid material that is derived from oil refining. Petcoke is processed from the final cracking process – a thermo-based chemical engineering process that splits long chain of Hydrocarbons of Petroleum into shorter chains — that takes place in units termed Coker units.
Rotary kilns have been used successfully for many years to produce calcined coke for the aluminium industry and they offer a high level of automation, performance and flexibility. Shaft calciners make a high bulk density, coarse particle size product and several papers have been published recently highlighting these benefits.

One emerging coal-based technology is the rotary hearth furnace, in which pellets of coal and iron ore are heated above 1300 °C by natural gas burners for a retention time of less than 13 minutes. The hot pellets may be melted in an EAF to produce pig iron, or charged hot to an EAF steelmaking furnace.
