New experimental data for CO2 solubility in the aqueous solutions of N-Methyldiethanolamine (MDEA) and 1-Butylpyridinium tetrafluoroborate ([Bpy][BF4]) ionic liquid (IL) are reported. The experiments were conducted in a static high pressure equilibrium cell. Solubility of CO2 was performed in various solution's compositions of IL and MDEA at a wide temperature range of (298.15 to 343.15) K and pressures up to 4 MPa. The experimental results revealed that by increasing weight percent of IL, the absorption capacity of aqueous mixtures diminishes. It was also observed that the main capacity of CO2 loading in the absorbent solutions belonged to MDEA through chemical absorption whereas its concentration was more effective than IL in gas solubility. The experimental results are correlated using a semi empirical model with a good accuracy.
