The steel industry is the primary consumer of petroleum coke that is high-quality as a significant product of refining oil. Carbon-shaped, it can be used as fuel for electric arc or blast furnaces. The low ash and sulfur levels make it a great recarburizer to help manufacturers achieve better quality steel products.
The demand for petroleum coke in the steel industry is anticipated to show an average growth of 2 percent until 2034 due to its use as a carbon source in blast furnaces as well as electric arc furnaces to aid in the production of high-quality steel. It is also used for the production of graphite anodes used in aluminum smelting. The need for premium petcoke that is low in sulfur is driven by the automotive, construction, packaging and aerospace industries, in addition to others.
Petroleum coke is the tough solid byproduct from refinement of petroleum, which is produced by coking heavy residue from the distillation process for crude oil (atmospheric and vacuum distillation, catalytic cracking and delayed coking). It's composed of 90-97percent carbon and a small amount each of oxygen, nitrogen and hydrogen. Nickel and vanadium are additionally present. Fuel coke is available in three different forms, depending on the nature of crude oil and the production process: metallurgical, shot, and fuel coke.
The metallurgical coke is employed in the steel industry to produce graphite electrodes and recarburizers which are crucial to the smelting of iron ore and also for gasification of coal. It is usually mixed with coal in coking ovens to decrease reactivity and improve mechanical strength It can also be used as an alternative to coal for the pulverized coal injection system.
In the process of calcination, coke is heated up to high temperatures and cooled to remove impurities. The resultant product, referred to as calcined petroleum coke or CPC is then tested to make sure it meets specific criteria. This includes tests for contamination as well as uniformity and density. Drying is a second crucial step in which the CPC is carefully heated to remove moisture, without triggering any unwanted reactions.
The calcination and drying phases are essential to the creation of high-quality recarburizers designed for iron ore smelting because they determine the final performance qualities of the recarburizer. It is crucial to use precise control and measurement tools to evaluate the performance of recarburizers. This may include chemical and physical analysis including rheometry as well as x-ray tests to determine the how much coke is sized. The results of tests are used to alter the recarburization process in order to get the desired performance properties. The testing methodologies differ based on the specific application however, they all focus on evaluating the chemical and structural composition of the coke to ensure that it meets the requirements of industry. The latest analytical technologies like high-resolution spectrums and atomic absorption are able to assist in this. Steel industry workers will get Recarburizers that are of the best quality. These results help improve the efficiency of the recarburizers, and extend their life span.
