Massive Growth for Needle Coke Industry

Petroleum coke, abbreviated coke or petroleum coke, is a final solid material rich in carbon that is derived from petroleum refining and is a type of the group of fuels called cokes. Petcoke is coke that, in particular, is derived from a final cracking process, a thermo-based chemical engineering process that splits long-chain petroleum hydrocarbons into shorter chains, which takes place in units called coking units. Put succinctly, coke is the "carbonization product of high-boiling hydrocarbon fractions obtained in the processing of petroleum (heavy residues)". Petroleum coke is also produced in the production of synthetic crude oil (syncrude) from bitumen extracted from the oil sands of Canada and the Orinoco oil sands in Venezuela.

In petroleum coking units, residual oils from other distillation processes used in petroleum refining are treated at high temperature and pressure, leaving petroleum coke after expelling gases and volatiles and separating light and heavy oils remaining. These processes are called "coking processes" and more typically employ chemical engineering plant operations for the specific delayed coking process.

This coke can be fuel grade (high in sulfur and metals) or anode grade (low in sulfur and metals). Raw coke that comes directly from the coker is often called green coke. In this context, "green" means raw. Further processing of the green coke by calcination in a rotary kiln removes residual volatile hydrocarbons from the coke. The calcined petroleum coke can be further processed in an anode firing furnace to produce anode coke of the desired shape and physical properties. Anodes are used primarily in the aluminum and steel industry.
