Absorption of CO2 in aqueous mixtures of N-methyldiethanolamine and guanidinium tris(pentafluoroethyl)trifluorophosphate ionic liquid at high-pressure
In this paper, the solubility of CO2 in aqueous blends of N-methyldiethanolamine (MDEA) and guanidium tris(pentafluoroethyl)trifluorophosphate [gua]+[FAP]− ionic liquid was measured at 313.15, 333.15 and 353.15 K and at partial pressures up to 3 MPa. Reported data were loading capacity (mol CO2/tota...

| description | In this paper, the solubility of CO2 in aqueous blends of N-methyldiethanolamine (MDEA) and guanidium tris(pentafluoroethyl)trifluorophosphate [gua]+[FAP]− ionic liquid was measured at 313.15, 333.15 and 353.15 K and at partial pressures up to 3 MPa. Reported data were loading capacity (mol CO2/total mol) as a function of CO2 partial pressure at equivalent temperature. A simple correlation was used to predict the solubility of CO2 in the mixtures. The predicted data showed good agreement with the experimental data. In this study, it has been found that adding [gua]+[FAP]− into the aqueous MDEA has lowered the absorption capacity and this effect was significant at higher concentrations. |
