VPSA-950Nm³/h(O₂) PSA Oxygen Generator

Typical Product

Output, purity and pressure

Notes: Nm³ indicates it is under the condition of 0.101325 MPa(A) and 0.

• The output and pressure of gaseous product are measured at the battery limit of the plant, and the range of temperature is 2040.
• The plant can run during the 50-110% loading of the design condition.

Process Description:

      The complete set of pressure swing adsorption (PSA) oxygen generation system is composed with blower, vacuum pump, switching valve, adsorber, oxygen balance tank, oxygen booster and oxygen storage tank. The feed air with particle impurities removed is cleaned of moisture and nitrogen by molecular sieve. The oxygen (including argon) is non-adsorption component, and goes from the top outlet of adsorber to oxygen balance tank as product.

      When the adsorber conducts the adsorption to a certain degree, the adsorbent will reach saturation condition. It can utilize vacuum pump to vacuumize the adsrober through switching valve, by which way the adsorbent is generated.

Applications and Advantages:

      The PSA is widely applied in metallurgy, chemical industry, national defense, medical treatment, petroleum, electron and environmental protection, etc. And it owns the following advantages compared with the other air separation technology:

1. High product purity & flexibly adjusted
2. Low power consumption
3. Simple process
4. Separate various gases without complex preprocessing procedure
5. Small investment, low operation cost, easy maintenance, less maintenance time and high rate of operation
6. Computer controls the PSA system with high degree of automation, easy operation, and can achieve full automatic operation.
7. High reliability of the plant
8. Long service of adsorbent
9. Good environmental benefit
