Does the penetration time determine the adsorption time?
The larger the gas volume, the shorter the adsorption time. Simply put, the degree of penetration can be determined by checking the CO2 content at the outlet of the purified gas; once the adsorbent reaches a certain level of saturation, penetration occurs, and the CO2 content at the outlet increases accordingly.
