Abstract

A generalized thermodynamic framework for correlating the vapor–liquid equilibria of aqueous primary, secondary and tertiary alkanolamine solutions is presented. The model uses Universal Functional Activity Coefficient (UNIFAC) and translated modified Peng–Robinson equation of state to correlate the activity and fugacity effects of the solution, respectively. New UNIFAC binary interaction parameters are reported for aqueous monoethanolamine, diethanolamine and N-methyldiethanolamine solutions for a wide range of temperature, pressure and concentration. The results are in excellent agreement with experimental data.
