Viscosity Measurement and Correlation of Unloaded and CO2-Loaded 3-Amino-1-propanol Solution

This paper reports new viscosity data for unloaded and CO 2 -loaded aqueous 3-amino-1-propanol (3A1P) solutions. For the unloaded system, experiments were performed over the whole concentration range at temperatures between 298.15 and 373.15 K. In the case of a CO 2 -loaded system, measurements were performed at fi ve di ff erent CO 2 -loadings ranging from 0.13 to 0.54 mol of CO 2 /mol of 3A1P at 0.30 and 0.50 3A1P mass fractions. The experimental data were also regressed using available methods from the literature.
