ABSTRACT

The physical properties of densities, viscosities and refractive indices, which are important in kinetics and mass transfer processes were measured for aqueous CO2 loaded and unloaded (EAE) solutions applied in CO2 absorption in the temperature range from 293.15 to 323.15 K at atmospheric pressure. Due to the limitation of the instrument and corrosive behavior with increasing concentration, the mass fractions (w1) of aqueous EAE solutions selected were: as 0.089, 0.178, 0.267 and 0.356, which correspond to the molar concentrations of 1, 2, 3 and 4 mol*L-1, respectively. The determined density, viscosity and refractive index data for binary EAE+H2O and ternary CO2+EAE+H2O systems were correlated using Weiland et al. model, Redlich-Kister equation, extended Arrhenius equation, and a new proposed empirical function. All the calculated density, viscosity and refractive index data fitted well with experimental values at all operational conditions.
