PKU Pioneer and Nanyang Hanye Special Steel have signed an agreement for the construction of a VPSA oxygen plant for a blast furnace ironmaking project in China.
Hayne Special Steel currently has an annual output of four million tonnes of medium, and heavy steel plates and hopes the new plant will further increase that production.
Increasing the steel capacity, however, leads to higher oxygen demand to ensure the smooth running of the ironmaking blast furnace. In order to serve its demand, the company needs the oxygen to fill an oxygen gap of approximately 20000Nm3/h.
The cost is high based on the oxygen, approximately $0.2-0.28/m3, however, by adopting the oxygen plant, the investment can be reduced to approximately $0.03-0.035/m3.
Taking into consideration equipment depreciation and other factors, a total operating cost of more than $140,773 will be saved annually.
