How PSA Oxygen Generators Work with Molecular Sieve Adsorption?

PSA (Pressure Swing Adsorption) oxygen generator is a reliable solution for industrial oxygen production. Using advanced molecular sieve technology, it separates oxygen from nitrogen in compressed air to deliver high-purity oxygen efficiently.

How It Works?

Compressed air is first cleaned through a filtration and drying system to remove moisture, oil, and impurities. It then enters dual adsorption towers filled with molecular sieve — special materials that selectively adsorb nitrogen. Because nitrogen is adsorbed much faster than oxygen, the result is oxygen with a purity of ≥93%.

After a short cycle (8–12 minutes), the tower undergoes regeneration: pressure is reduced and nitrogen is desorbed using a vacuum pump. Towers alternate automatically, allowing continuous oxygen output.


Key Features:

Oxygen Purity: 93% ± 3%

Energy Saving: 0.3–0.5 kWh/m³ oxygen, 30% less than cryogenic systems

System Efficiency: Oxygen recovery rate ≥85%

Control System: Sensors and PLC monitor pressure, purity, and temperature in real time

Applications

Metallurgy / Steelmaking

– Oxygen is used in blast furnaces and steel refining to improve combustion and reduce energy consumption.

Glass Manufacturing

– Oxygen-enriched combustion increases furnace temperatures, improves product quality, and reduces emissions.

Welding and Metal Cutting

– Oxygen is essential for oxy-fuel welding and cutting processes, generating high-temperature flames.

Pulp and Paper Industry

– Applied in oxygen bleaching and delignification for a more environmentally friendly process.
