Product Description


The characteristics, process principle and process flow of PSA decarburization technology are basically the same as that of PSA in purifying hydrogen. The difference lies in that the raw gas of PSA is CO2 rich mixture and the product gas can be H2, N2 & CO.


  • Production technology is mature and operation is reliable
  • The process flow is simplified and easy to operate accompanied with a prompt action for both start-up and shut-down
  • Automation is high, and the operation and control are simple and reliable
  • Operation is stable, safe and reliable
  • Less land occupation and investment can be recovered in a short time
  • Cost-effective in operation and production
  • Recover CO2 with high concentration >90%

Process Principle

De-carbonization separates carbon dioxide from other gaseous components by utilizing the nature of adsorbent which is selected adsorption of carbon dioxide in gas mixture under pressurized condition.


Meanwhile, adsorbents release adsorbed carbon dioxide gas under the depressurizing condition as to enable adsorbents to regain adsorbing capacity. One stage or two stages of operation are adopted based on the client’s different requirements for the contents of carbon dioxide as a product so as to ensure the yield of valid components and stable index.

Process Description

CO2 rich feed gas is pretreated and then entered into the PSA system from the bottom of the adsorption tower. Purified gas (H2, N2, CO) is obtained from the top of the tower. From the bottom of the tower, we get the desorption gas (main content is CO2) so to recover CO2 or release it into the atmosphere.


  • Capacity: 5,000~100,000 Nm3/h
  • Remaining CO2 : ≤ 0.2%(v/v)
  • Pressure : 0.3~3.6MPa(G)
  • Hydrogen Recovery: ≥98%(v/v)
  • Nitrogen recovery: ≥90%(v/v)
  • CO recovery: ≥92%(v/v)


  • CO2 removal and purification from water gas and semi water gas
  • CO2 removal and purification from shift gas
  • CO2 removal and purification from pyrolysis gas of methanol cracking
  • CO2 removal or concentration from other sources of CO2 –rich gases
