The Industrial Scale Air Separation system operates based on low-temperature cryogenic rectification technology.
Ambient air is filtered and compressed before entering a molecular sieve purification unit, where moisture, carbon dioxide, and trace hydrocarbons are removed. The purified air then passes through a high-efficiency aluminum plate-fin heat exchanger, where it is cooled to cryogenic temperatures prior to separation.
Within the double-column distillation configuration, oxygen and nitrogen are separated according to their boiling point differences. A turbo expander provides refrigeration energy, maintaining thermal balance and reducing overall power consumption.
Through optimized thermodynamic design and advanced process control, the system achieves:
Oxygen purity up to 99.6–99.8%
Continuous industrial gas output
Stable operation under fluctuating load conditions
Optional nitrogen and argon recovery
Engineering-led process optimization ensures consistent production performance while minimizing energy loss across the entire operating cycle.
