Product Specification

GNEE On Site Oxygen Generator Manufacturers PSA Oxygen Gas Generator

PSA oxygen generator is an intelligent on-site oxygen generator, which utilizes pressure swing adsorption technology to produce high-quality oxygen with stable purity continuously. The series pressure swing adsorption oxygen generator adopts a new product design concept and advanced oxygen production technology, with skid-mounted design, is suitable for on-site oxygen supply of various purity.

How PSA Oxygen Generators Work

Composition of Air

Before diving into the technical aspects of PSA technology, it’s important to understand the composition of the air we breathe. The atmosphere consists of approximately:

• 78% nitrogen
• 21% oxygen
• 1% argon, carbon dioxide, and trace gases
• Since nitrogen and oxygen make up the vast majority of air, PSA technology focuses on separating these two gases to provide high-purity oxygen.

The Principle of Adsorption

The heart of a PSA oxygen generator lies in the process of adsorption. Adsorption is the phenomenon where certain materials can capture gas molecules on their surface. PSA oxygen generators use a material called zeolite as the molecular sieve. Zeolite has a microporous structure that allows it to selectively adsorb nitrogen molecules while allowing oxygen to pass through.

The PSA Cycle

A PSA oxygen generator operates in a cyclic manner, alternating between high and low pressure to achieve oxygen separation. The process can be broken down into four basic steps:

Compression of Air: Ambient air is compressed and passed through a filtration system to remove dust, moisture, and other impurities. This compressed air is then directed into one of two adsorption towers filled with zeolite molecular sieves.

Adsorption Phase: In the first adsorption tower, the zeolite selectively adsorbs nitrogen from the air. Since oxygen molecules are smaller than nitrogen molecules, they pass through the sieve and exit the tower as concentrated oxygen (typically 90-95% pure). This oxygen is collected in a storage tank for immediate use.

Desorption Phase (Pressure Swing): Once the adsorption tower becomes saturated with nitrogen, the pressure inside the tower is reduced. This pressure swing releases the adsorbed nitrogen from the zeolite, allowing the tower to be regenerated for the next cycle.

Switching Between Towers: PSA oxygen generators use two adsorption towers, which work in tandem. While one tower is in the adsorption phase, the other is undergoing desorption and regeneration. This ensures a continuous supply of oxygen.

The cycle typically takes only a few seconds to complete, meaning PSA oxygen generators can provide a steady and uninterrupted supply of oxygen

Advantages

The PSA generator can be operated under normal atmosphere, and its advantages are listed as following:

1.Low Production Coat.

2.Simple Process and Less Equipment, High Automation and Operation Convenience.

3.Quick starting and easy stopping. The system can provide product gas in 30 minutes after starting and also can be operated intermittently.

4.Low working pressure and safely.

5.Good flexibility. The purity and output for oxygen can be easily adjusted.
