In this study, the Modified Skarstrom cycle is employed to evaluate the process-level performance of MOFs in post-combustion CO2 capture. This cycle consists of five steps: pressurization, adsorption, heavy reflux (HR), counter-current (CnC) depressurization, and light reflux (LR). The cycle begins with pressurization, where pressure rises from low pressure (PL) to adsorption pressure (PH) using the flue gas as feed. During the adsorption step, the flue gas is fed into the column for CO2 adsorption, and N2 exits from the other end. In the heavy reflux step, the feed stream is stopped, and the heavy product collected from the light reflux step is fed into the column to increase CO2 concentration at the inlet. The pressure then drops back to PL during the depressurization step, and CO2 is collected. Finally, during the light reflux step, the light product from the adsorption step is used to purge remaining CO2 in the column, with a fraction of the CO2 product used as feed during the heavy reflux step.
