Abstract

An industrially attractive solvent to capture C02, has been developed by inco~oratingth e desirable properties of ionic liquids(1Ls) as well as mines through mixing of the targeted ILs with mine to form hybrid solvents for the effective capture of CO2. In the present work, ILs of two different families namely, bis(2- hydroxyethyl)ammoniurn acetate ([bheaa]) and 1-butyl-3-methylimidazolium tetraflouroborate ([bmim][BF4]) have been chosen to form a new binary1 ternary solvents in combination with monoethanolamine (MEA) and water for the solubility of C02. In order to establish the physical properties for the new binary [ (bheaa + water); (bheaa+ MEA); (bmimBF4+water); BmimBF4+MEA) / ternary [(bheaa + MEA + Water) (bmimBF4 + MEA + Water)] solvents, density, viscosity and refractive index measurements have been made at T = (293.15 to 353.1 5) K for the whole composition range. Based on the measured values the effects of temperature and concentration of individual spicies have been discussed in detail and suitable correlations have been proposed. The excess properties, namely, the excess molar volume f,vi scosity deviation Arl, as well as the refractive index deviation AnD, have been deduced from the measured density, viscosity and refractive index values respectively for all the binary and ternary systems studied in the research. The Redlich Kister equation was used to correlate the estimated excess properties for the binary systems while the Cibulka equation was used to correlate the excess properties for the ternary systems.
