- Abstract
In this work, physical properties such as density, viscosity and refractive index of aqueous sodium l -prolinate (SP) and piperazine (PZ) as a solvent for CO 2 removal were measured at temperatures from 298.15 to 343.15 K at 5 K intervals. Different mass fractions ( w 1 + w 2 ) % of aqueous blends of (SP + PZ) were 0.10 + 0.02, 0.10 + 0.05, 0.20 + 0.02, 0.20 + 0.05, 0.30 + 0.02, and 0.30 + 0.05. It was observed that the density, viscosity and refractive index increase with increasing the mass fraction, and decrease with increasing temperature. The density data were used for theoretical evaluation of thermal expansion coefficients. It was found that thermal expansion coefficient increases slightly with increasing concentration and temperature. Empirical correlations were applied to the measured physical properties in order to calculate the predicted data. The statistical error analysis was carried out, which showed good agreement between experimental and predicted data.
