Example of validation of simulated transient histories against experimental data for adsorption of CO2 and N2 in zeolite 13X using a basic 4-step VSA cycle. Evolution of CO2 purity (a), temperature histories at three locations in the column (b), pressure history for one cycle at CSS (c), CO2 composition and flow rate at the outlet of the adsorption step (d), CO2 composition and flow rate at the outlet of the blowdown step (e), CO2 composition and flow rate at the outlet of the evacuation step (f). Symbols represent experimental data and lines indicate numerical simulations. Reprinted with permission from Estupiñan Perez et al.120 Copyright 2019 Elsevier.
