Density and Viscosity of CO<sub>2</sub>-Loaded Aqueous 2-Amino-2-methyl-1-propanol (AMP) and Piperazine (PZ) Mixtures
Densities and viscosities of aqueous 2-amino-2-methyl-1-propanol (AMP)/piperazine (PZ) solutions with and without CO<sub>2</sub> are measured from 20 to 80 °C at ambient pressure. Redlich-Kister-based correlations are proposed for the excess molar volumes and viscosity deviation of the binary and ternary mixtures. Empirical correlations are developed to quantitatively describe the effect of CO<sub>2</sub> on the density and viscosity of the aqueous AMP/PZ solutions. The experimental data and correlations developed can be used in the design and simulation of AMP/PZ-based CO<sub>2</sub> capture absorption plants.
