A number of technological improvements have occurred in the production process for calcined petrol coke. They are now expected boost market growth. These advancements are designed to increase the overall efficiency and productivity of the industry, and to reduce environmental impact. Petcoke demand can be reduced by using alternative materials. This is an important factor for future market growth, as it will reduce the need to import petroleum coke from overseas.
The global calcined petroleum coke (CPC) market has been growing rapidly, and it is projected to continue doing so over the next five years. The growth can be attributed to many different factors. These include the increase in steel demand, progress in the power and cement industries, global growth in supply of heavy oil, and support from government initiatives for a sustainable environment.
CPC can be produced in a shaft or rotary kiln by heating green petroleum coke to high temperature. It is used to remove volatile substances from GPC in order to make it more carbon-rich and useful for fuels or other chemicals. It is energy-intensive to calcine, and so several technologies were developed in order to increase its efficiency.
Currently, most of the calcining in the world is done with a rotary kiln. In China, however, shaft kiln technology is becoming more popular. The shaft kiln technology is more energy efficient than the rotary kilns and produces coke that has a reduced sulphur content. They are also easier to use and require less maintenance.
In most cases, waste heat is recovered to use the heat produced by the burning sulphur. The heat produced is then used to create steam that can either be used as a process heater or for generating electricity using a steam generator. The exhaust gas is then scrubbing with SO2 to reduce the concentration of sulfur dioxide in it. This technology is now a requirement for new calcining plants, and it is being developed for existing calcining plants as well.
Two main segments make up the global market for calcined petcoke: Fuel Grade, and Anode Grade. In terms of market value, the Fuel Grade sector is largest and accounts for more than 55 percent. The Anode Grade segment is smaller but still a significant segment of the market. CPC of the anode grade has a combination unique to it that makes it suitable for manufacturing aluminum anodes.
The housing construction market in India is expected to grow over the next few years, which will drive the demand for calcined petcoke. India's growth in population and its economic success are both driving the need for infrastructure. A growing steel industry in India will lead to increased demand for calcined petroleum coke. The steel-making process requires high thermal energies. Demand for calcined PETCOKE is predicted to rise.
