Petroleum coke is a byproduct of oil refining that can be used for a variety of industrial purposes. It is usually stockpiled at refineries and transported to calcining plants for further processing. Fuel grade petcoke can be burned in conventional cyclone, PC, or fluidized bed boilers to produce electricity.
However, its high sulfur content poses environmental problems, and it must be burned with SO2 scrubbing technology to mitigate this problem.
Petroleum coke is a solid carbon byproduct of oil refinement that is used in various industrial applications. The primary use is for aluminum production, where it acts as a carbon additive to increase electrical conductivity. It is also used to make graphite and steel. The coke is produced by delayed coking of residues obtained from crude oil distillation units in oil refineries. The unprocessed coke is known as green or raw petcoke, and the processed product is referred to as calcined petcoke or metallurgical coke.
To produce calcined petcoke, the green coke is heated in a rotary or shaft kiln to remove volatile matter and moisture. The resulting coke is hard but brittle, with a high percentage of fixed carbon and low ash content. Calcined petcoke can be produced to meet a variety of specifications, including a high sulfur level or a low sodium level. The lower sulfur calcined petcoke is preferred by many of the major aluminum smelters because it has a lower sodium content and can be used to replace anode material.
Petroleum coke is a solid carbon-rich byproduct of oil refining that can be used as an alternative to coal. It is usually burned in a rotary kiln to produce calcined petroleum coke (CPC). CPC has a low ash content and high carbon content, making it an excellent fuel for electric power plants. It is also used in brick and glass manufacturing.
Calcined petroleum coke is produced by heating raw petcoke in a rotary kiln at temperatures between 1200 and 1350°C. This process removes excess moisture and extracts residual hydrocarbons, resulting in a denser, more electrically conductive product.
The global calcined petroleum coke market is growing rapidly due to increased demand for aluminum products, development of the steel industry and favorable government initiatives regarding green environment. The calcined petroleum coke market is divided into different end-user industries, such as graphite electrodes for electric arc and induction furnaces, chemical production, fertilizers and titanium dioxide pigment. The primary aluminum sector accounts for the majority of calcined petroleum coke demand.
Petroleum coke is a solid byproduct of crude oil refining. It is a black, carbon-based material that contains small amounts of sulfur, nitrogen, and metals. It is produced by delayed coking in the coker unit of a crude oil refinery. The fuel grade coke that exits the coker is referred to as green petroleum coke, or petcoke. The coke must be further processed in a rotary kiln to eliminate residual volatile matter and increase the percentage of elemental carbon.
Calcined petroleum coke is the primary feedstock for the Hall-Heroult aluminum smelting process. This is due to its low impurity levels and easy availability. The remaining demand for calcined petcoke is met by the steel and titanium dioxide production industries, mostly as recarburizers.
In addition, calcined petroleum coke is used as an insulator in electric arc and induction furnaces. It is also a source of graphite electrodes, which are used in the aluminum and titanium smelting industry. Studies have demonstrated that emissions from calcining facilities are well below public health standards and do not pose a significant threat to human health.
The global calcined petroleum coke market has a bright future, driven by rising iron & steel production and development of power generation sector in emerging regions. In addition, increasing demand for aluminum from the construction industry also contributes to the growth of this market.
Calcined petcoke is made by placing high quality green petroleum coke (GPC) into rotary kilns where it is heated to extremely high temperatures. This process eliminates excess moisture and restructures the crystalline structure of GPC to create a denser, more electrically conductive product.
The demand for high-quality calcined petroleum coke will continue to grow as the aluminum industry continues to expand around the world. In addition, growing infrastructural activities and population rise in countries like India will drive the market for calcined petcoke over the forecast period. The report covers an in-depth analysis of the calcined petroleum coke market including key trends, drivers and challenges. Moreover, the report also highlights opportunities for current and future investors in this market.
