Isothermal Vapor–Liquid Equilibrium Data for Water + Diisopropanolamine, Water + N-Methyldiethanolamine and Diisopropanolamine + N-Methyldiethanolamine Systems

Accurate modeling of thermodynamic vapor–liquid equilibrium of aqueous amines and amine mixtures is essential for the design of new CO 2 capture processes. Isothermal vapor–liquid equilibrium data were measured for the binary systems of water + diisopropanolamine (DIPA), water +  N -methyldiethanola...

Summary:Accurate modeling of thermodynamic vapor–liquid equilibrium of aqueous amines and amine mixtures is essential for the design of new CO 2 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.
