Density and viscosity data and relevant correlations are essentially needed to perform mathematical modelling and simulations for the design of process equipment. Correlations that are developed to cover a range of concentrations and temperatures help to use them in mathematical modelling and simulations of absorptiondesorption processes. In this study, a density correlation was proposed for 3A1P (3-Amino-1-propanol) + H2O mixtures. The McAllister three body model was adopted to correlate kinematic viscosity data of MEA (monoethanol amine) + H2O mixtures and kinematic viscosity data for 3A1P + H2O mixtures. The Eyring's viscosity model based on absolute rate theory was used to correlate dynamic viscosity data. A Redlich-Kister type polynomial was proposed to fit the excess free energy of activation for viscous flow for 3A1P + H2O mixtures. The developed correlations were able to represent density and viscosity data with accepted accuracy and can be used to perform engineering calculations.
