Core Working Principle
The system operates based on cryogenic air separation, utilizing differences in boiling points among air components under extremely low temperatures.
1. Air Compression and Purification
Ambient air is compressed and passed through purification units where moisture, carbon dioxide, and hydrocarbons are removed. This prevents freezing and ensures stable downstream operation.
2. Cryogenic Cooling Process
Through multi-stage heat exchange, the air temperature is gradually reduced to approximately −200°C, transforming it into liquid air.
3. Fractional Distillation Separation
Inside the distillation columns:
Nitrogen vaporizes first due to its lower boiling point
Argon is extracted at intermediate stages
Oxygen is collected at the column bottom as a high-purity product
This continuous thermodynamic process enables long-term stable gas production with consistent purity levels.
