Experimental Measuring Methods and Modeling of Density and Viscosity of Alkanolamine Solutions and Liquid Solvents

Alkanolamine solutions are extremely used in acid gases treatment in gas and oil refineries. Thermal and physical equilibrium and transport properties such as density and viscosity of loaded and unloaded alkanolamine solution have significant role in process designing of striping units and also in software simulation designing of absorption and desorption amine units. In this work, all experimental methods of measuring the density and viscosity of amine solution and models presented in literature are summarized and density and viscosity of pure and aqueous solution of N,N-dimethylformamide (DMF) at the entire range of composition and atmospheric pressure are measured at the temperature range of (303.15 – 333.15) K. Excess quantities of those mentioned properties were obtained and modeled by using Redlich-Kister equation.
