Abstract

The Eyring absolute rate theory (EART) based methodology has been used for estimation of the dynamic viscosity of CO2 loaded aqueous solutions of a representative amine-monoethanolamine (MEA). The electrolyte-NRTL model is applied to estimate the activation free energy of the solution and consequently enable prediction of the dynamic viscosity of the electrolyte CO2:MEA:H2O system. According to EART for the dynamic viscosity of asolution (Equation presented) η, η0, V, V0, R and ΔFn, are the dynamic viscosity of solution and pure solvent, the solution and pure solvent molar volume, gas constant and activation free energy for the flow process, respectively. The ΔFn was generally related to the Gibbs free energy of mixing, f(ΔGn mix).
