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...
