Petroleum coke, a typical type in the casting of and it's called graphite per sulphonate, is a material derived from (petroleum, heavy oil or gas oil). This substance is the product of the refining of crude oil. It is a way to light heavy-duty oil so that it can be delivered by separating crude oil or light derivatives from the refineries. Unfortunately, this process is being delivered by purchasing oil from our country in the next countries, and oil coke is delivered to Iran, but refineries We did not do this, and the Ministry of Oil does not license it to the private sector. However, coking is a delayed way to turn oil residues into useful products.
The process's overall design is that heavy vacuum points are injected into the furnace and heat up to 480 ° F. The output of this furnace is sent to the coke towers at a temperature range of 466-490 psi. In these towers, the cracking process is carried out and light products are made from high and coke produced from the bottom of the tower after the completion of the process. The coke production temperature, the amount of cracking and the content of sulfur and coke ash varies depending on the feed type. The above-mentioned petroleum coke can not be used in the same way and then calcified.
The product above is melting as a carbon additive for use in casting, which is increasingly used in steel making. Special steel also has the ability to use this product. It is also suitable for use in cement, aluminum, and purifying fuel industries.
