Working Principles for PSA Oxygen Generator
- In the process of generating enriched oxygen gas from ambient air, an oxygen plant employs a unique technique called Pressure Swing Adsorption (PSA). This process takes advantage of the synthetic Zeolite Molecular Sieve’s ability to selectively absorb nitrogen while allowing oxygen to pass through.
- Ambient air typically consists of approximately 21% oxygen, 78% nitrogen, 0.9% argon, and 0.1% other trace gases. To separate oxygen from this mixture, the air is compressed and directed into the PSA system.
- Within the PSA system, the compressed air is introduced to the Zeolite Molecular Sieve bed. As the air passes through the bed, the Zeolite’s pore system selectively absorbs nitrogen, allowing oxygen gas to be produced as the desired product.
- The synthetic Zeolite Molecular Sieve acts as a molecular filter, capturing and retaining nitrogen while letting oxygen molecules pass through. This separation is achieved due to the differing affinity of the molecular sieve for nitrogen and oxygen.
- By utilizing the Pressure Swing Adsorption process, the oxygen plant effectively concentrates the oxygen content while removing nitrogen from the compressed air. The resulting product is enriched oxygen gas suitable for various applications.
- An oxygen generation plant utilizes two vessels filled with Zeolite Molecular sieve as adsorbers to separate nitrogen from oxygen. The process begins with compressed air flowing through one of the adsorbers. The Zeolite Molecular sieve selectively adsorbs the nitrogen, allowing the oxygen to pass through and exit as the desired product gas.
- Once the adsorber becomes saturated with nitrogen, the inlet airflow is switched to the second adsorber. Meanwhile, the first adsorber undergoes regeneration. This regeneration process involves desorbing the nitrogen by depressurizing the adsorber and purging it with some of the product oxygen. This purging helps remove the trapped nitrogen from the adsorbent material.
- The cycle is then repeated, with the pressure continually swinging between a higher level during adsorption (production of oxygen) and a lower level during desorption (regeneration of the adsorber). This cyclic operation ensures a continuous supply of purified oxygen.
- By utilizing the selective adsorption properties of Zeolite Molecular sieve, the oxygen generation plant achieves the separation of nitrogen and oxygen. The cyclic process of adsorption and regeneration allows for the continuous production of high-quality oxygen, meeting the requirements of various applications.
