The petroleum coke produced by the refining of oil is rich in carbon. It is a hard black solid similar in appearance to coal. The majority of the petcoke in the market is made up of carbon. Small quantities of oxygen, nitrogen, hydrogen and sulfur are also present. The coke's chemical composition depends on several factors, including the crude source, the coking condition and the time of the coking. The composition of the coke can be used as a way to identify its origin.
The most common way to use calcined oil coke, which is environmentally friendly, is as a source of energy. The coke can be burnt to produce electricity or heat. This raw material can be used in the manufacture of graphite. It can be a good alternative to natural gases, which are often expensive and difficult for transport.
Calcined petroleum coke, a green fuel that is also environmentally friendly, can be used for the production of many metals and chemical products. This is a key component in aluminum production. This is also used as a cheap alternative to more expensive materials in the steel industry. It is also widely utilized in the manufacturing of paints. It is even used to create titanium dioxide, an important mineral that is used for paints, sunscreens, and plastics.
Environmentally friendly calcined petroleum coke can also be used as a replacement for natural gas in coal-fired power plants. The resulting emissions from calcined petroleum coke are significantly lower than traditional fossil fuels. It can also be used to make synthetic natural gas. To make SNG from calcined oil coke, it is combined with a little nitrogen and then compressed in a high pressure cylinder.
The temperature of the rotary kiln can be adjusted between 1200 and 1450 degrees Celsius (2192 to 2560 degrees Fahrenheit). The extreme temperatures modify the coke’s crystal structure and remove excess moisture. The coke will be cooled at less than 20 @C after calcination.
The brittleness of petroleum coke can cause staining in bulk carrier holds. This can result in the need for extensive cleaning procedures. This heavy sludge also poses a danger to safety and fire.
Gas Technology Institute, in collaboration with Superior Graphite Company has developed a patented technology to resolve these issues. The fluidized bed technology converts green petroleum into environmentally friendly calcined oil coke. The calciner utilizes an electrothermal liquidized bed system with integrated waste heat utilization. This technology produces a product that is more efficient and emits less pollution. It is also capable of using a variety of feedstocks to generate clean, cost-effective energy. The process can also be scaled-up to suit the needs of different industries. The project partners intend to commercialize and deploy the technology at Superior's Hopkinsville Kentucky facility.
