The determination of physical properties and the obtaining of parameters related to thermodynamic models are essential in the design and simulation of industrial units for gas absorption and desorption by amine solvents. In this work, the viscosity and density of the binary and ternary mixtures of Ethanolamine and 2-amino-2-methyl-propanol (AMP) and water were measured at a temperature range of (303 to 343) K. Appling the thermodynamic models, the excess volume of the binary mixtures was correlated with the Redlich-Kister model and the mean relative error was less than 3% for all data. The dynamic viscosity for binary systems were determined by Eyring-NRTL and Eyring-Wilson models and used to predict the ternary mixture behavior. The results showed that the Eyring-Wilson model had better prediction than Eyring-NRTL model. Ultimately, the kinematic viscosity was correlated by the Redlich-Kister expansions and its temperature-dependent parameters were determined.
