“…p v represents the saturated vapour pressure of DES at the experimental temperature. In present work, the values of p v are indirectly determined using the TGA analysis according to literature method [41]. In brief, the evaporation rates of DES and reference substance (RS) were recorded under the same conditions, respectively.…”

“…The most remarkable property of ionic liquids is that their vapor pressure at room temperature is negligibly small [2,3]. This non-volatility is the reason why ionic liquids are considered to be promising candidates for replacement of conventional volatile organic solvents.…”

“…75,76 The cost of steam has been estimated using the SRMC assuming that the efficiency of the boiler is 90%. Given that ionic liquids are very low volatile liquids, 35,77 and chemically stable compounds, we assume that only 10% of the solvent is replaced annually. A conservative estimate of the cost of a bulk ionic liquid has been set to $10 per kg.…”

Ionic liquids (ILs) have the potential to outperform traditional solvents for CO2 capture, with a great many ILs having been studied to date. In this contribution we present a new approach for their evaluation, and identify which physical properties most infl uence their technical and economic performance. This work highlights a range of potential challenges that ionic liquids will face before they can be applied at process scale, and identifi es some key research opportunities. Ionic liquids have been extensively investigated as promising materials for several gas separation processes, including CO 2 capture. They have the potential to outperform traditional solvents, in terms of their capacity, selectivity, regenerability and stability. In fact, hundreds of ionic liquids have been investigated as potential sorbents for CO 2 capture. However, most studies focus on enhancing equilibrium capacity, and neglect to consider other properties, such as transport properties, 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 a range of monetised and non-monetised process performance indices.Our results demonstrate that whilst most research effort is focused on improving CO 2 solubility, viscosity, a transport property, and heat capacity, a thermochemical property, might preclude the use of ionic liquids, even those which are highly CO 2 -philic, and therefore increased effort on addressing the challenges associated with heat capacity and viscosity is an urgent necessity. This work highlights a range of potential challenges that ionic liquids will face before they can be applied at process scale, and identifies some key research opportunities.
