【 摘 要 】

In this study, the viscosities (η) of the aqueous mixed-solvent system of diethylene glycol (DEG) and 2-amino-2-methyl-1-propanol (AMP) were investigated at normal atmospheric pressure over the range of temperature of 303.15 - 343.15 K and across varying component mole fractions range [0.02 to 0.60 for DEG (x1 ), 0.02 to 0.60 for AMP (x2 ), and 0.20 to 0.80 for H2O (x3 )]. The calculated properties were fitted to a modified equation originally proposed by Grunberg and Nissan for the viscosity of liquid mixtures to correlate temperature and composition dependency of the measured property. In comparison to literature values, the uncertainty of the kinematic viscosities was approximated to be + 1.0 %, and that the correlations used satisfactorily represent the effects of temperature and composition on the viscosities of the considered mixed-solvent system as shown by the low overall average absolute deviations obtained in the calculations. The properties obtained and reported in this work are, in general, of adequate correctness for most engineering-design calculations, such as the design of absorption process for carbon dioxide capture using mixed-solvents as absorbents.
