AB - Post-combustion CO<inf>2</inf> capture by pressure-vacuum swing adsorption (PVSA) is gaining increasing interest due to the evolving energy landscape and the industry's decarbonization efforts. Within a hybrid energy system composed of conventional fossilfuel-based power generation balancing renewable electricity sources, PVSA systems must be able to accommodate for transient conditions arising from intermittent operation. In this work, a model-based approach to investigate the operational flexibility of a PVSA unit applied to a 1,000 MW coal power plant is presented. The comparative analysis of two distinct adsorbents reveals a clear trade-off between operability and economics. Specifically, Zeolite-13X exhibits a lower capture cost, while ZIF-36-FRL demonstrates more flexibility in the ranges of high- and low-pressures at which the unit can be operated. The most flexible nominal operating point was successfully identified for each adsorbent using the developed framework, highlighting the importance of incorporating into the design process operational robustness. The latter is represented by a novel metric of normalised space size (NSS). This work demonstrates that significant improvement in NSS can be achieved, while increasing capture cost only marginally. This result highlights that optimal adsorbent selection for CO<inf>2</inf> capture should account for operational flexibility.
