SOLUTION
Air Separation Industry Solutions
Scheme Overview
In the petrochemical and metallurgical industries, air separation and purification equipment is extensively used to separate air into O2, N2, Ar, and other rare gases, which serve as feed gases and on-site protective gases. The ST9000CN air separation process analysis system is an analytical system specifically designed and manufactured for continuous online monitoring of air separation and purification equipment. The ST9000CN analysis system ensures the quality and purity of gases during the air separation process and guarantees the normal operation of equipment such as oxygen generators.
