Working Principle – PSA Technology
The 500 LPM PSA Oxygen Generation Plant operates on Pressure Swing Adsorption (PSA) technology, a proven method of separating oxygen from nitrogen using molecular sieves. The process ensures continuous oxygen supply by alternating between adsorption and regeneration cycles in twin-tower PSA beds.
1. Air Compression & Filtration – Ambient air is compressed, dried, and filtered to remove moisture, dust, and oil particles before entering the PSA unit.
2. Adsorption Cycle – The compressed air passes through Zeolite Molecular Sieves, which selectively adsorb nitrogen while allowing oxygen to pass.
3. Regeneration Cycle – Once one PSA tower is saturated with nitrogen, the system automatically switches to the second tower, while the first tower releases nitrogen into the atmosphere and regenerates.
4. Continuous Oxygen Flow – The cyclic process repeats continuously, ensuring a steady supply of high-purity oxygen.
