Petroleum coke, or petcoke, is a product produced from all types of oil (light/heavy crudes) during the oil refining process. Many different products are extracted from a barrel of crude oil in addition to gasoline, diesel and jet fuels. Petroleum coke just one of the many. Petroleum coke is not a new product and has been produced since the 1930s.
Calcining of petroleum coke is done in the rotary kiln. The kiln components consist of shell, tires, carrying stations, seals, refractory and a drive train, which ... sections of the plant area, are readily available to the system operator through the graphic screens provided by Outotec. Optimization Control System (OCS)
In kraft pulp mills, lime mud (mainly CaCO 3) from the causticizing plant is washed, dewatered and calcined in a lime kiln to produce lime (CaO) for reuse in the causticizing process.
Coke-calcining plants receive green petroleum coke from oil refineries. The green coke is blended and fed into rotary kilns operating up to 2800°F under a reducing condition. The material exits the rotary kiln as calcined coke with a correct crystalline structure and electrical conductivity properties.

Kilns of this type are usually fed with stone ranging in size from 15mm to 40mm and are fuelled by a range of fuels including coal, petroleum coke, natural gas and waste derived fuels. They are used to produce Dolomitic lime and higher purity quicklime, used for the manufacture of low-carbon steel, fibreglass and healthcare products.
Petcoke is supplied as solid lumps, which need to be fine- ly pulverized before being fed into the lime-kiln burner. The two major capital equipment items required for pulverized petcoke burning are a petcoke storage and feed system and a multi-fuel-firing burner.
However, Petcoke is ideal for burning in lime kilns, where the sulphur combines with various salts of calcium to form sulphates, thus limiting the SO2 emission. Low Ash Content : Petcoke has extremely low ash content, which eliminates the need to handle and dispose high quantity of ash associated with combustion of Indian coal having 15-35% ash.
Fuel: Feul grade coke represents ~ 80 % of the worldwide petroleum coke produced and is used as fuel in electric power plants, cement kilns, and other industrial facilities. Further, Calcined petcoke is …
For a hypothetical lime kiln that burns only petcoke (that is, with a substitution rate) containing 6 wt% S, the total S input with petcoke would be approximately 10 kg/t CaO.
