Abstract
To understand capturing and/or enhanced gaseous selectivity of industrial flue gases containing CO2 and SO2 using room-temperature ionic liquids, we have developed a ternary equation of state (EOS) model for a CO2/SO2/1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([hmim][Tf2N]) system. The present model is based on a generic RK (Redlich−Kwong) EOS, with empirical binary interaction parameters of each binary system. These interaction parameters have been determined using our measured VLE (vapor−liquid-equilibrium) data for SO2/[hmim][Tf2N] and CO2/[hmim][Tf2N] and literature data for CO2/SO2. The validity of the present EOS has been checked by conducting ternary VLE experiments for the present system. With this EOS, isothermal ternary phase diagrams and solubility (VLE) behaviors have been calculated for various (T, P, and feed compositions) conditions. For large and equimolar CO2/SO2 mole ratios, the gaseous selectivity is nearly independent of the amount of the ionic liquid addition. Howe...
