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 technologies -- the high-temperature conversion from green coke to calcined coke alters the material in key three ways: Drying.

Abstract. Delayed petroleum coke is calcined in an internally-fired vertical shaft kiln. A downwardly-moving bed of green coke is preheated in the top of the kiln by rising combustion gases, then heat soaked at calcining temperatures in the intermediate section of the kiln, and finally cooled by recycle gas moving upwardly from the lower part of the kiln.

At present,the petroleum coke is mainly calcined by vertical shaft furnace or rotary kiln to meet the requirement of prebaked anode used for aluminium reduction in China.Vertical shaft furnace for calcination is quite different from rotary kiln for calcination in the principle of calcination process,calcined coke quality,product availability,production capacity,energy consumption,operation ...

Compared with studies on a rotary kiln, fewer studies have been conducted on numerical simulations of petroleum coke calcination in a vertical shaft calciner. Zhang et al. 9 – 11 studied the gas combustion in the flue and the temperature and pressure distribution in the pot via the computational fluid dynamics (CFD) numerical simulation method.

Shaft kilns constitute majority of all the kilns presently being used for the production of lime. The types of shaft kilns are (i) mixed feed shaft kiln (MFSK), (ii) parallel flow regenerative kiln (PFRK), (iii) annular shaft kiln (ASK), and (iv) other kilns. Shaft kilns are vertical in design, upto 30 m (metres) in height and with a diameter ...

The principle of the PFR kiln, i.e., the calcination of lime in one shaft and the preheating of the stone with the hot kiln gas in the other shaft, is also used in the Finelime ® kiln. Thus its heat consumption is significantly lower compared to rotary kilns. Since 1989, when it was first introduced onto the market,

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).
