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.

Ten frequently asked Questions about PSA oxygen generators

1.What is a PSA oxygen concentrator?

A PSA oxygen concentrator is a device that separates and purifies high-purity oxygen from the air using pressure swing adsorption (PSA) technology. It utilizes molecular sieve adsorbents to achieve the separation and purification of oxygen based on the differential adsorption properties of oxygen and nitrogen in the molecular sieve.

2.How does a PSA oxygen concentrator work?

• A PSA (Pressure Swing Adsorption) oxygen concentrator operates by utilizing molecular sieve adsorbents and their adsorption properties to separate and purify oxygen from the surrounding air. The process involves a cyclic operation in which compressed air is directed through a bed of molecular sieve adsorbents.
• During the cycle, compressed air is introduced into the concentrator and directed into the molecular sieve bed. The molecular sieve adsorbents have a higher affinity for nitrogen molecules compared to oxygen molecules. As the compressed air flows through the bed, the nitrogen molecules are selectively adsorbed onto the surface of the molecular sieve, while the oxygen molecules pass through.
• To ensure continuous oxygen supply, the PSA oxygen concentrator typically consists of multiple molecular sieve beds. While one bed is in the adsorption phase, selectively adsorbing nitrogen and allowing oxygen to pass through, the other beds undergo a regeneration process. During regeneration, the pressure in the bed is reduced, causing the adsorbed nitrogen molecules to desorb and be released into the atmosphere.
• This cyclic operation of adsorption and regeneration enables a constant production of purified oxygen. While one bed is adsorbing nitrogen, the other beds are being regenerated, ensuring an uninterrupted supply of oxygen.
• The effectiveness and efficiency of a PSA oxygen concentrator depend on the adsorption characteristics of the molecular sieve adsorbents. These adsorbents are carefully selected and designed to have a higher affinity for nitrogen, allowing for the selective adsorption and separation of oxygen from the surrounding air.
• In summary, the working principle of a PSA oxygen concentrator is based on the differential adsorption properties of nitrogen and oxygen on molecular sieve adsorbents. Through a cyclic process of adsorption and regeneration, the concentrator achieves the separation and purification of oxygen, providing a reliable source of high-purity oxygen for various applications, including medical therapy and industrial processes.

​3.What are the advantages of a PSA oxygen concentrator?

PSA oxygen concentrators have several advantages:

They can generate oxygen on-demand in real-time, eliminating the need for oxygen storage.
They are easy to operate and maintain.
They can be used indoors without the need for external gas pipelines.
They produce high-purity oxygen, suitable for medical-grade applications.
4.What are the main uses of a PSA oxygen concentrator?
PSA oxygen concentrators are widely used in medical, pharmaceutical, food processing, and electronic industries. They provide high-purity oxygen to meet the requirements of various industries and applications, such as oxygen therapy in hospitals and oxygen combustion in industries.

5.What is the oxygen purity achievable with a PSA oxygen concentrator?
Typically, PSA oxygen concentrators can provide oxygen with a purity of 93% or higher. For specific requirements, the oxygen purity can be further increased through additional oxygen purification processes.

6.Does a PSA oxygen concentrator require maintenance?
Yes, PSA oxygen concentrators require regular maintenance and servicing to ensure their proper operation and extended lifespan. Maintenance tasks include cleaning filters, inspecting, and replacing adsorbents, among others.

7.What is the noise level of a PSA oxygen concentrator?
PSA oxygen concentrators generally have low noise levels, typically below 50 decibels. However, the noise level may vary depending on the model and brand of the concentrator, but most are designed to operate quietly.

8.Does a PSA oxygen concentrator require a power source?
Yes, PSA oxygen concentrators require a power source to function properly. Typically, they need to be connected to a 220V AC power supply with a frequency of 50Hz.

9.Does a PSA oxygen concentrator need a compressed air source?
Yes, a PSA oxygen concentrator needs to be equipped with a compressed air source. It uses compressed air as the oxygen feedstock for its operation.

10.Is it necessary to frequently replace the adsorbents in a PSA oxygen concentrator?
Adsorbents are critical components in a PSA oxygen concentrator, and their lifespan is generally long, lasting several years. However, over time and with increased usage, the adsorbents gradually lose their effectiveness and need to be checked and replaced periodically. The specific replacement cycle depends on usage and the model of the oxygen concentrator, so it is recommended to follow the manufacturer's guidelines for proper operation.
