The amount of carbon dioxide that is removed from the unit (per day) is 2352kg. I've designed the adsorption column.

Absorption vs Adsorption Difference and Comparison Diffen

Absorption is the process in which a fluid is dissolved by a liquid or a solid (absorbent).Adsorption is the process in which atoms, ions or molecules from a substance (it could be gas, liquid or dissolved solid) adhere to a surface of the adsorbent. Adsorption is a surfacebased process where a film of adsorbate is created on the surface while absorption involves the entire volume of the
