PSA Oxygen Plant

A PSA oxygen plant is a facility that produces oxygen using Pressure Swing Adsorption (PSA) technology. This process separates oxygen from ambient air by exploiting the differences in how gases adhere to a special adsorbent material, typically nitrogen-preferential adsorbent. Here’s a clearer breakdown:

●Principle: Air, which contains ~21% oxygen and ~78% nitrogen, is compressed and passed through a column filled with nitrogen-preferential adsorbent.  preferentially adsorbs nitrogen under pressure, allowing oxygen to pass through.

●Pressure Swing: When the nitrogen-preferential adsorbent becomes saturated with nitrogen, the pressure is reduced, releasing the nitrogen (desorption) and regenerating the nitrogen-preferential adsorbent for the next cycle.

●Output: The system delivers high-purity oxygen (typically 90–95%) continuously, suitable for medical, industrial, and laboratory applications.

●Advantages: On-site production, reduced dependency on cylinder supply, cost-efficient for hospitals or industries requiring steady oxygen flow.

A PSA oxygen plant reliably produces high-purity oxygen, typically between 93% and 95%, in accordance with the Indian Pharmacopoeia 2018 standards (minimum 90%, maximum 96%). Designed for continuous operation, PSA plants ensure a stable, on-site supply of medical- and industrial-grade oxygen, with minor purity variations well within safe and acceptable limits.
 

A PSA (Pressure Swing Adsorption) oxygen plant produces oxygen directly from ambient air using a highly efficient adsorption process. Compressed air is first passed through filters and dryers to remove dust, moisture, and oil. It then enters a bed filled with nitrogen-preferential adsorbent molecular sieves, which selectively adsorb nitrogen while allowing oxygen to pass through. Once the nitrogen-preferential adsorbent is saturated with nitrogen, the pressure in the bed is released, allowing the nitrogen to be expelled and the nitrogen-preferential adsorbent to regenerate for the next cycle. By alternating between adsorption and desorption cycles, the system continuously delivers high-purity oxygen, typically 93–95%, suitable for medical, industrial, and laboratory applications. Modern PSA plants are fully automated, energy-efficient, and capable of providing a reliable on-site oxygen supply without the need for storage cylinders.

The daily oxygen production of a PSA plant depends on its model, size, and design capacity. Smaller medical-grade systems can generate tens of cubic meters per day, suitable for hospitals and clinics, while larger industrial-grade plants can produce hundreds of cubic meters per day, meeting the needs of factories, laboratories, and large healthcare facilities. Production can be adjusted according to real-time demand, ensuring efficiency and cost-effectiveness.
 

No. PSA plants generate oxygen directly from ambient air, eliminating the need for external oxygen cylinders. This not only reduces the costs and logistics of cylinder supply but also ensures a continuous, on-demand oxygen supply. Hospitals and industries can rely on PSA systems for uninterrupted oxygen delivery, improving safety, convenience, and operational efficiency.

They are widely used in:

●Healthcare facilities (hospitals, clinics, nursing homes)

●Industrial processes (steel, chemical, glass manufacturing)

●Laboratories and research centers

●Environmental and water treatment facilities

●Any process requiring a stable supply of high-purity oxygen
