Chemical Air Separation Unit
Chemical air separation unit is a large industrial equipment based on cryogenic separation technology, used to efficiently separate air into high-purity oxygen (O₂), nitrogen (N₂), argon (Ar) and other rare gases. This device is widely used in petrochemical, coal chemical, metallurgy, electronic manufacturing and energy fields, meeting the strict demands of high-purity gases in different industries.
Core technology features
1. Deep cold distillation process
- Multi-stage compression + expansion refrigeration technology is used to cool the air to -170℃~-200℃, and the boiling point difference is used to achieve accurate separation of oxygen, nitrogen and argon.
- Key equipment: molecular sieve purification system, main heat exchanger, double-stage distillation tower, low-temperature liquid pump.
2. High-efficiency and energy-saving design
- Optimize the heat exchange network to reduce energy consumption, and the energy consumption per unit of oxygen is as low as 0.35~0.45 kWh/Nm³ (depending on the scale).
- It can be equipped with heat pump distillation or liquid boost circulation technology to further improve energy efficiency.
3. Intelligent control
- Integrate DCS/PLC control system to monitor flow, purity, pressure and other parameters in real time, and support remote operation and maintenance.
