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。
