Working principle:

When the feed gas Enter the PSA machine, as the adsorption capacity of adsorbent on carbon dioxide (CO2) in the adsorption bed varies with the pressure, CO2 in the raw gas is absorbed under pressure, and it is not easy to absorb components -- hydrogen H2 and nitrogen N2 from the outlet of the adsorption bed as purification gas output. During decompression and evacuation, the impurity components such as CO2 absorbed are desorbed from the adsorbent, and the adsorbent is regenerated。

According to the specific requirements of users, different processes can be used to decarbonizes and recycle high purity CO2。

Feed gas:

Conversion gas

Others need to remove CO2 gas

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。
