PSA Oxygen Generator
Based on the principle of pressure swing adsorption, high-quality zeolite is used as the adsorbent. Under a certain pressure, due to the kinetic effect, the diffusion rates of oxygen and nitrogen on carbon molecules are quite different. The nitrogen molecules are adsorbed by zeolite in large quantities, and the oxygen molecules are enriched in the gas phase to achieve oxygen and nitrogen separation.
- Purity: 93%±3%
- Oxygen volume: 1~2000Nm3/h
- Pressure: 0-5.5bar
- Dew point: -40℃
Air compressor: Air is sucked in from the environment and compressed to a higher pressure by a compressor. The compressed air usually has a higher temperature and pressure
Cooler: The compressed high-temperature air passes through the cooler to reduce the air temperature. The cooled air is usually cooled by an air cooler or cooling tower to remove some of the heat.
Drying tower: In some systems, the dehumidified air will pass through a drying tower (such as a molecular sieve dryer) to further remove the remaining moisture and other impurities to ensure that the air is dry enough to improve the purity and quality of the nitrogen.
PSA (Pressure Swing Adsorption): In the PSA system, the dried compressed air passes through the adsorption tower and passes through the molecular sieve medium. The nitrogen is retained on the adsorbent, while oxygen and other gases are discharged. High-purity nitrogen is obtained through periodic pressure changes and adsorbent regeneration.
Gas storage tank: The separated nitrogen is stored in the gas storage tank for subsequent use. The gas storage tank can be a high-pressure gas cylinder or a large gas storage tank, depending on the demand for nitrogen.
Control system: The entire nitrogen production system is equipped with a control system to monitor the operating status of each stage, including air pressure, temperature, nitrogen purity, etc. The control system can automatically adjust operating parameters, optimize system performance, and provide fault alarms and maintenance reminders.
Through the above process, the nitrogen production system can efficiently extract nitrogen from the air to meet the needs of different applications
