For example, if a particular industrial process configuration can have a dehumidifier unit before the adsorption step, then structure (a) would be potentially interesting despite its low CO 2 /H 2 O selectivity. This structure would also be promising in regions with very low water vapor content in the atmosphere. The stronger binding of CO 2 to the MOF would become the more dominating factor in choosing this material. On the other hand, if there is no dehumidifier unit, then structures (b) and (c) would be the better choice because of their high CO 2 /H 2 O selectivity. Structure (c), satisfying both requirements, is likely to be an interesting candidate in both scenarios: with and without humidity. Thus, it would be interesting to evaluate these materials one step further, on a process level, and we are looking into it as future work.
