Does the recovery of CO2 have an impact on the operation of the pressure swing adsorption decarburization system?
Thread Content
After CO2 recovery through pressure swing adsorption decarburization using the single-stage method, since the pressure of CO2 entering the recovery system is required to be between 0.02 and 0.05 Mpa, it may be necessary to install a water seal before the vent pipe. What impacts might this have on the pressure swing adsorption decarburization system? Those who have experience with CO2 recovery systems, please provide some guidance
There isn’t much of an impact; it’s just that the process is slightly more complicated； On the contrary, it has many advantages in terms of environmental protection, energy conservation, and improved efficiency.

The outlet resistance of the vacuum pump will increase, which may affect the desorption of the adsorbent; of course, it ultimately depends on the choice of vacuum pump used by the original poster. In the case of initial reverse venting, since the CO2 concentration is not very high, it can be directly recycled back into the system. Of course, it is also possible to send the CO2 to a recovery unit for processing before returning it to the system to recover hydrogen and nitrogen; however, this increases the cost associated with removing CO2. The problem is that reverse venting involves more resistance compared to normal venting, which means the pressure before vacuuming increases, and this in turn affects the efficiency of vacuum-based desorption
What is the specific process flow for recovering carbon dioxide using pressure swing adsorption? Could the people upstairs explain in detail? I’d like to learn about it*. Thank you
