摘要：
Accurate modeling of thermodynamic vapor–liquid equilibrium of aqueous amines and amine mixtures is essential for the design of new CO2 capture processes. Isothermal vapor–liquid equilibrium data were measured for the binary systems of water + diisopropanolamine (DIPA), water + N-methyldiethanolamine (MDEA) and DIPA + MDEA by using headspace gas chromatography at 423 K. The DIPA + MDEA system has azeotrope. The experimental binary vapor–liquid equilibrium data of water + DIPA, water + MDEA and DIPA + MDEA binary systems were well correlated with NRTL model.
