PSA Oxygen Generator
Shenger Gas industrial PSA oxygen generators employ mature Pressure Swing Adsorption (PSA) technology to directly separate oxygen from air with purity up to 93%–95%. The system features high integration and automated operation, making it suitable for continuous, large-scale industrial oxygen applications. It eliminates reliance on liquid-oxygen purchases and cylinder handling, enabling on-site oxygen generation and significantly lowering gas-supply costs.
Core Technology: PSA Working Principle & Structural Design
1. Working Principle
The unit delivers compressed air into adsorption towers filled with specialized molecular sieves. Under pressure, the sieves preferentially adsorb nitrogen, allowing oxygen to be enriched and delivered. Nitrogen is then desorbed during depressurization, regenerating the sieves. Dual-tower alternating cycles ensure continuous oxygen output.
2. System Components
- Air Compression System: Supplies clean compressed air.
- Pre-treatment Unit: Removes oil, dust, and moisture to protect the molecular sieves.
- Adsorption Tower Assembly: Core separation module using high-strength pressure vessels.
- Control System: PLC-based automation with touch-screen HMI; supports remote monitoring.
- Oxygen Buffer & Purification (Optional): Further enhances purity and pressure stability.
