solubility of carbon dioxide in aqueous mixture of aminoethylethanolamine + sulfolane at high pressure and different temperatures

In recent years, the emission of greenhouse gases especially carbon dioxide has been increased# since co2 is accounted for as a gas pollutant and leads to global warming, the removal of carbon dioxide is an important step in a gas capturing process# in this study, the solubility of carbon dioxide in mixtures of the chemical and physical solvents at different compositions is measured using a static high-pressure equilibrium cell# the measurements are carried out for the two different blends of sulfolane + aminoethylethanolamine(aeea) + water with the mass compositions of (20-20-60) wt#%, and (10-20-70) wt#% , respectivly, at 313#15 and 328#15 k within the total pressure range of 100 – 5300 kpa# the results show that for both systems at the given composition, by increasing temperature the loading of co2 was reduced at a fixed partial pressure of co2# in addition by increasing the partial pressure of co2 at a fixed temperature, the co2 absorption was enhanced# moreover, the present findings showed that co2 solubility was enhanced by increasing either sulfolane or aeea concentration# however, at low acid gas loading, the co2 loading was reduced by enhancing the sulfolane concentration#
