Calcined Petroleum Coke (CPC)

According to the different content of sulfur and other metals, green petroleum coke (GPC) can be used for different industrial purposes. The low-sulfur anode-grade petroleum coke is the raw material for the production of CPC and it is produced after calcination at high temperature. CPC is mainly used as anode paste for aluminum smelting and raw material for pre-baked anode. More than 70% of CPC worldwide is used for aluminum smelting. The CPC produced by our company is high-quality low-sulfur coke, which is mainly exported to large aluminum companies in the world, such as Emirates Global Aluminum, Bahrain Aluminum, Saudi Arabia Ma'aden Aluminum, etc., for aluminum production.


Green Petroleum Coke (GPC)

Green Petroleum Coke (GPC) is a by-product in the process of petroleum refining, which has low reuse value for refineries. After crude oil is separated from light and heavy oil by distillation, the heavy oil is transformed into GPC through thermal cracking. The main element composition is carbon, accounting for more than 80%. It also contains nitrogen, chlorine, sulfur and heavy metal compounds. According to the content of sulfur and other metals, the GPC can be used for different industrial purposes. Low-sulfur anode-grade GPC is the raw material for the production of CPC. Anode-grade petroleum coke is low-sulfur coke (with sulfur content less than 3%). While meeting the production requirements, the GPC purchased also can be sold directly.



In the process of calcining GPC, the volatile matter contained in GPC can provide sustainable fuel for high-temperature calcination of the calciner to ensure the normal production of the calciner. At the same time, the waste heat of flue gas generated in the calcination process can be effectively utilized by the heat pipe boiler and the negative pressure guarantee can be provided for the calciner. The steam production ratio is up to 1:1.3. The steam produced by the waste heat boiler, except for a small amount of self-use, more than 98% of steam produced is provided to other production enterprises in the industrial park as clean energy.


Ammonia sulfate

In the process of calcination, calcined smoke and dust is generated. After the dust removal process, it enters the ammonia desulfurization system. The SO2 in the flue gas reacts with NH3 to produce ammonia sulfate. This advanced process is independently designed and developed by the company to create a green circular economy.



In the smelting process of iron and steel products, the smelting loss of carbon element in molten iron is often increased due to factors such as smelting time, holding time, and long overheating time, resulting in a decrease in the carbon content in molten iron and not reaching the expected theoretical value of smelting. The carbon-containing substances added to make up for the carbon content lost during the steel melting process are called carburetors
