TY  - JOUR
AB  - Ionic Liquids have been extensively investigated as promising materials for several gas separationprocesses, including CO2capture.  They have the potential to outperform traditional solvents, interms of their capacity, selectivity, regenerability and stability.  In fact, hundreds of ionic liquidshave been investigated as potential sorbents for CO2capture.  However, most studies focus onenhancing equilibrium capacity, and neglect to consider other properties, such as transport prop-erties, and hence ignore the effect that the overall set of properties have on process performance,and therefore on cost.  In this study, we propose a new methodology for their evaluation using arange of monetised and non-monetised process performance indices.  Our results demonstratethat whilst most research effort is focused on improving CO2solubility, viscosity, a transport prop-erty, and heat capacity, a thermochemical property, might preclude the use of ionic liquids, eventhose which are highly CO2-philic, and therefore increased effort on addressing the challengesassociated with heat capacity and viscosity is an urgent necessity.  This work highlights a rangeof potential challenges that ionic liquids will face before they can be applied at process scale, andidentifies some key research opportunities.
