摘要：
The NRTL model has been used to correlate the data for the aqueous alkanolamine systems of (MEA+H2O), (DEA+H2O) and (MDEA+H2O). The model was successfully applied to correlate simultaneously the excess enthalpy, vapour-liquid equilibria, and low temperature activity coefficients. A large database of data was collected for the investigation and it covers a wide range of composition, temperature and pressures. It was found that the form of the binary interaction parameters used by Posey (1996) with a variable non-randomness parameter gave the best results.
