Technical Working Principle of PSA Oxygen Generators

Pressure Swing Adsorption (PSA) is a physical gas separation process that leverages the different adsorption characteristics of nitrogen and oxygen on Zeolite Molecular Sieves (ZMS).

1. Air Intake & Conditioning

   • Ambient air is compressed (typically 0.6–0.8 MPa).

   • Oil, moisture, and particulates are removed via pre-filters and dryers.

2. Adsorption Phase

   • Compressed air passes through a ZMS column.

   • Nitrogen and trace gases are preferentially adsorbed by the zeolite under pressure.

   • Oxygen molecules pass through as the primary product gas.

3. Desorption (Regeneration) Phase

   • Once the molecular sieve becomes saturated, the system switches towers.

   • The first tower is depressurized, releasing adsorbed nitrogen back into the atmosphere.

   • The second tower continues oxygen production, ensuring uninterrupted supply.

4. Delivery

   • The product gas (oxygen with 93 ± 3% purity) is stored in a buffer tank.

   • Output pressure is typically 0.4–0.6 MPa, suitable for direct connection to ozone generators.

• Twin-Tower Adsorption Design → Continuous supply with automatic switching.
• High-Efficiency Molecular Sieves → Premium ZMS with long service life and stable performance.
• Integrated Skid-Mounted Systems → Compact footprint, plug-and-play operation.
• PLC/Controller Based Automation → Minimal operator intervention, full monitoring of pressure cycles.
• Optional Oxygen Storage Tanks → For demand balancing in large ozone plants.

• Purity: 90–95% oxygen (93 ± 3% standard).
• Pressure: 0.4–0.6 MPa output, optimized for ozone generators.
• Dew Point: Typically -40 °C, ensuring moisture-free oxygen supply.
• Energy Efficiency: 0.6–1.5 kWh per Nm³ of oxygen, depending on model size.
• Cycle Time: Adsorption/desorption cycles every 30–120 seconds, controlled automatically.

While PSA oxygen generators are often paired with Plasma Ozone Generators, they are also widely used in:

• Healthcare & Medical Oxygen Systems (hospitals, clinics, oxygen therapy).
• Aquaculture & Fisheries (pond oxygenation, RAS systems).
• Industrial Combustion (glass, ceramics, metallurgy).
• Wastewater & Sewage Treatment (enhancing aerobic processes).
• Food & Beverage Processing (oxygenation for fermentation and packaging).
