Petroleum Coke is produced from the petroleum refining process. The first stage is extracting raw materials (crude oil) from the ground after drilling an oil well. The second stage is transporting these materials to the oil refinery.
Oil refineries refine these raw hydrocarbons into usable products for the market-for example, petroleum oils, gasoline, diesel, kerosene, and other derivatives.
Refining petroleum hydrocarbons includes equipment, stages, techniques, and chemical reactions to obtain the final product.
At this stage, raw materials are heated to extremely high temperatures in distillation towers and pressed to high pressures. Then, each hydrocarbon compound separates at a certain pressure and temperature.
The residues of these derivatives remain in the form of petroleum liquids. Here, those liquids are transferred to special units called "coking units" to complete the filtering process. Then, these liquids are processed at a specific temperature and pressure to produce Petroleum coke in the form of solids after purging them of all gases and volatile materials. Finally, all remaining light and heavy oils are separated.
The resulting petroleum coke at this stage is called Green Petroleum Coke (CVP). In short, still needs to be processed. Petroleum Coke can be used here in some applications, but others require more processing and are called "Calcined Coke". This process means transferring petroleum coke to a rotary kiln to remove the remaining volatile hydrocarbon residues.
The calcined petroleum coke can be further processed in an anode baking oven. It produces coke, which is used mainly in manufacturing steel or aluminium.
For storage and transportation, such as coal, petroleum coke is stored in large piles in bags or silos. Conveyors, hopper belts, and trolleys can easily transport it.
Because petroleum coke is carbon-rich, it must be stored in a dry environment.
It will form a hard solid called "damp coke" if wet. It is a tricky substance that is difficult to remove. It can often be easily broken or removed through the use of a ripper, which is a high-pressure water hose.
