Oxygen is a strong oxidising gas, flammable and explosive, so safety measures should be taken in its design and manufacture. When choosing materials, all metals in contact with oxygen must be chemically stable and not easily oxidised. Each component should be degreased. The shaft seal should be sealed with nitrogen pressure difference and also ensure the vacuum of the oil system. All large air separation unit parts and pipings in contact with oxygen should be earthed to prevent static electricity. In addition, firewalls should be provided for oxygen unit piping and valves.
The Kaifeng Dear air separation overhaul management team, with accurate fault information and real-time warning of faults on site, can easily achieve real-time viewing and historical queries on product faults. By setting data such as upper and lower limit values and change rates for analogue quantities, the management team can generate timely warnings, and can split time and product statistics and export alarm summary reports. Alarm information includes product attributes, alarm generation time, alarm elimination time, alarm acknowledgement time, alarm acknowledgement person and other information.
