摘要：
In this work, vapour-liquid equilibrium of CO2 in aqueous mixture of 2-amino-2-methyl-l-propanol (AMP) and hexamethylenediamine (HMDA) is studied in the temperature and pressure range of 303.15-333.15 K and 1-100 kPa respectively. Concentration of the aqueous solutions used are (5mass% HMDA+25mass% AMP), (10 mass% HMDA+20 mass% AMP), (15mass% HMDA +15mass% AMP) and (20 mass% HMDA+10 mass% AMP). Density of aqueous amine solution is also measured in the same range of temperature and concentration. Redlich-Kister equation for excess molar volume is used to model density of the mixed solvent system. To correlate experimental CO2 solubility data, Kent and Eisenberg thermodynamic model is used. Equilibrium constants of bicarbamate formation reaction of HMDA and deprotonation reaction of AMP are regressed to fit experimental data with the model expression. Kent and Eisenberg model is found to predict the CO2 solubility in aqueous (HMDA + AMP) with good accuracy (AAD: 7.2%). (C)2017 Elsevier B.V. All rights reserved.
