Oxygen Plant
This factory was launched in line with the high goals of self-sufficiency of the complex and with the daily production of 20,000 kilograms of pure oxygen, it not only met its own needs, but it can also meet the needs of other companies that consume oxygen and water.
Oxygen, nitrogen and argon are essential gases for the steelmaking process, especially the production of quality steels. For example, the use of oxygen in the furnace helps to adjust the chemical analysis (due to the reaction of oxygen with carbon) and by increasing the temperature of the melt, it helps to reduce the cost of electricity and reduce the melting time. One of the uses of nitrogen and argon is in the part of the crucible furnace, where melt alloying takes place and for deoxygenation and homogenization of the temperature and chemical composition of the melt.
Oxygen production method
So far, the best and cheapest way to obtain pure oxygen is to use ambient air, which first takes the ambient air with powerful compressors, then this compressed air enters the turbine. This turbine heats the air It is cooled to -190 °C and enters the separator After separating the liquids, each one is stored in separate tanks.
Keeping very cold liquids
As mentioned, the temperature of liquid oxygen is very low (approx°c181-) is and because Liquid oxygen occupies less space and a larger volume can be stored. For this purpose, special tanks are required that can store liquids for a long time. In this unit, 5 tanks are installed in accordance with relevant standards for storing oxygen. has been
Transfer of gases to the smelter
Because the consumption of oxygen, nitrogen and argon in the factory is in the form of gas and with high pressure, 3 piston pumps with evaporators of these liquid gases °c190 to the pressurepsi 450 compressed into 3 tanks of 5000 kg It transports oxygen and 2000 kg of nitrogen and argon. These gases are sent to the production line at the desired pressure when needed, and the output pressure is adjusted by precise regulators.
