Abstract

The physical properties, such as densities, viscosities, and refractive indices, of aqueous solutions of potassium carbonate (PC) blended with glycine (Gly) as solvent blends for CO2 capture were measured. The properties were measured at ten different temperatures from (298.15 to 343.15) K. The mass fractions (w1+w2) of the (PC+Gly) blends were 0.05+0.01, 0.10+0.02, 0.15+0.03, 0.20+0.04, 0.25+0.05, 0.30+0.06, 0.35+0.07 and 0.40+0.08 %, respectively. An analysis of the experimental results showed that the densities, viscosities, and refractive indices of the aqueous (PC+Gly) blends increase with increasing concentration of potassium carbonate and glycine, and decrease with increasing the temperature. The experimental data of density, viscosity and refractive index were correlated by a least-squares method as a function of temperature. The predicted data were estimated from coefficients of correlation equations for all the measured properties, and reported with standard deviation (SD). The experimental data were consistent with the predicted data.
