Notes:1. Nm3 is based on 0.101325MPa(A),0℃.

2. Output and pressure of product gases are measured at the battery limit of plant, temperature range: 20~40℃.

3.The plant can be running in design mode with adjustment of 50-110%.


Process Description:


The whole VPSA is consisted of blower, vacuum pump, switch valve, adsorber, oxygen balance tank, oxygen booster and oxygen storage tank. Following the elimination of dust particles from feed air at the in the suction inlet filter, the feed air is boosted to 49-58 Kpa by roots blower, and after being cooled by subcooler, it enters into one adsorber, in which filled with adsorbent. The moisture, CO2 and other small amount gas component are adsorbed at the adsorber inlet by the activated aluminium oxide and molecular sieve filled at the bottom. While the oxygen (including argon) which are non-adsorption component goes out from the outlet at the top of adsorber, and then it is fed to the oxygen balance tank as product gas.


When the adsober conducts the adsorption to a certain degree, and the adsorbent will reach saturation condition, use vacuum pump to vacuumize the adsorber (be opposite with the adsorption direction), and the vacuum degree is -50-60 Kpa. The adsorbed moisture, CO2, nitrogen and other small amount gas component will be withdrawn and discharged to the atmosphere, and the adsorbent will be regenerated. Each adsorber conducts the following steps in switch:


---Adsorption

---Desorption

---Pressing


The above three basic process steps will be automatic controlled by PLC and switching valve system.


Applications:


PAS (Pressure Swing Adsorption) has been widely applied in the petroleum, chemical industry, metallurgy, electron, national defense, medical treatment and environmental protection, etc.


Competitive Advantage:

  1. Low power consumption
  2. High product purity, and can be adjusted flexibly
  3. The process is simple, and can separate various gases without complex preprocessing procedure.
  4. The plant is controlled by computer, which has advantages of high degree of automation, easy operation, and can achieve full automatic operation.
  5. Small investment, low operation cost, easy maintenance, less maintenance time and high rate of operation
  6. Long service of adsorbent
  7. High reliability of the plant
  8. Good environmental benefit
