ABSTRACT
The accurate design of acid gas treatment processes requires the knowledge of vapor liquid equilibrium of acid gas aqueous alkanolamine systems, and, consequently, that of the binary systems involved. This study presents: (a) vapor pressure measurements of pure 2-amino-2-methyl- 1-propanol (AMP), and (b) isobaric vapor liquid equilibrium (VLE) measurements at 66.7, 80.0 and 101.3 kPa of aqueous AMP solutions. The data measured in this work along with some excess enthalpy data, which were taken from the literature, were used for the thermodynamic modeling of the water/AMP binary system.
