The solubility of carbon dioxide in aqueous solutions of alkanolamines was measured by means of two experimental methods. The solubility of carbon dioxide was measured at 298 K with a static total pressure apparatus in solutions of water + diisopropanolamine (DIPA) having mass fraction of DIPA equal to 10.1%, 11.0% and 33.9%. The density of the water + DIPA solution was measured continuously during the experiments to investigate the changes in density introduced by the absorption of carbon dioxide. A correlation for the density of CO2-loaded aqueous solutions of DIPA is presented.The solubility of CO2 in aqueous solutions of methyldiethanolamine (MDEA) and of DIPA was measured at atmospheric pressure with a bubbling equipment at various temperatures between 298 and 353 K. The mass fraction of MDEA in the solutions was 10%, 20% and 49% and the mass fraction of DIPA was 10%, 20%, 25% and 35%.
