Abstract

In this paper, the solubility of CO ₂ in aqueous blends of N-methyldiethanolamine (MDEA) and guanidium tris(pentafluoroethyl)trifluorophosphate [gua] ⁺[FAP] ^- ionic liquid was measured at 313.15, 333.15 and 353.15K and at partial pressures up to 3MPa. Reported data were loading capacity (mol CO ₂/total mol) as a function of CO ₂ partial pressure at equivalent temperature. A simple correlation was used to predict the solubility of CO ₂ 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.
