(Vapour + liquid) equilibria (VLE) of CO2 in aqueous solutions of 2-amino-2-methyl-1-propanol: New data and modelling using eNRTL-equation
This work presents new experimental results for carbon dioxide (CO2) solubility in aqueous 2-amino-2- methyl-1-propanol (AMP) over the temperature range of (298 to 328) K and CO2 partial pressure of about (0.4 to 1500) kPa. The concentrations of the aqueous AMP lie within the range of (2.2 to 4.9) mol dm-3. A thermodynamic model based on electrolyte non-random two-liquid (eNRTL) theory has been developed to correlate and predict the (vapour + liquid) equilibrium (VLE) of CO2 in aqueous AMP. The model predictions have been in good agreement with the experimental data of CO2 solubility in aqueous blends of this work as well as those reported in the literature. The current model can also predict speciation, heat of absorption, enthalpy of CO2 loaded aqueous AMP, pH of the loaded solution, and AMP volatility.
