The technology of Purification CO2 by PSA Product introduction

After the mixed air containing carbon dioxide (CO2) enters the pressure swing adsorption (PSA) device adsorption tower, the adsorption capacity of the adsorbent in the adsorption bed is different with the change of pressure. CO2 in the raw gas is absorbed under pressure, and the components that are not easy to be absorbed are removed from the outlet of the adsorption bed. When decompression occurs, the adsorbed CO2 and residual impurities are desorbed and desorbed. The concentrated CO2 is refined, and one part returns to the PSA system and the other part is canned in the form of liquid products。

Working principle:

After the mixed air containing carbon dioxide (CO2) enters the pressure swing adsorption (PSA) device adsorption tower, the adsorption capacity of the adsorbent in the adsorption bed is different with the change of pressure. CO2 in the raw gas is absorbed under pressure, and the components that are not easy to be absorbed are removed from the outlet of the adsorption bed. When decompression occurs, the adsorbed CO2 and residual impurities are desorbed and desorbed. The concentrated CO2 is refined, and one part returns to the PSA system and the other part is canned in the form of liquid products。


Feed gas:

Fermentation gas、Conversion gas、Decarburization and regeneration gas

Mine Gas

Other mixed gases containing CO2


Control mode and characteristics


Control mode: The SPA device is controlled by the controller and meter. The controller can select DCS, FCS and PLC control system according to the scale and control requirements of the SPA device。

Characteristics: It not only realizes the conventional control of the system, but also realizes the expert control and adaptive optimization control of arbitrary combination and switching of multiple towers, which not only improves the operational flexibility of the device, but also ensures the long-term, stable and safe operation of the PSA device。
