Solubility of carbon dioxide in an aqueous mixture of methyldiethanolamine and N-methylpyrrolidone at elevated pressures

The solubility of carbon dioxide in a mixed solvent consisting of 40% methyldiethanolamine+50% N-methylpyrrolidone+10% water (all mass%) has been measured at seven temperatures in the range of 0–150°C at pressures up to 20MPa. A second liquid phase formed at elevated pressures and its locus was dete...

Summary:The solubility of carbon dioxide in a mixed solvent consisting of 40% methyldiethanolamine+50% N-methylpyrrolidone+10% water (all mass%) has been measured at seven temperatures in the range of 0–150°C at pressures up to 20MPa. A second liquid phase formed at elevated pressures and its locus was determined.
