In 2010, our company cooperated with changge jinhui stainless steel co., LTD to establish the first-stage oxygen production. In 2017, as the steel plant increased production, our company cooperated to establish the second-stage oxygen production and fully operated.

From the beginning of oxygen production to now, our company's operation team has formulated relevant regulations on production, safety, production and training, and taken preventive measures to ensure the normal operation of air separation.
Current goals of our operations team:
1. Completed oxygen production (4200000m cubed x12);Nitrogen yield (4200000m cubed x12) oxygen purity is above 99.65 and nitrogen purity is 10ppm.
2. Train workers' safety awareness and eliminate major equipment safety production accidents.
3. Guarantee the quantity of sufficient product gas for party a's unit.
