Abstract
High Resolution Image Download MS PowerPoint Slide Densities and viscosities of aqueous 2-amino-2-methyl-1-propanol (AMP)/piperazine (PZ) solutions with and without CO 2 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 2 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 2 capture absorption plants.
