In this study, new experimental data were reported for CO2 solubility in H2O 2-amino-2-methyl-1-propanol (AMP) methanol (MeOH) system by using a static-synthetic apparatus. The experiments were done in the temperature range of 313.15 – 353.15 K and the CO2 partial pressure range of 1.08 – 303.7 kPa. The concentrations (wt. %) of mixed AMP MeOH were 8.2 41.2, 16.5 32.2, 22.3 27.7 and 30.6 19.4. Also, the density of the hybrid solvent was measured using a pycnometer similar to concentration and temperature ranges. To correlate the experimental CO2 solubility data, three different models namely modified Kent-Eisenberg, Deshmukh-Mather, and artificial neural network (ANN) were used. The density data were correlated by Redlich-Kister equation. The results showed that the ANN modeling with an average absolute relative deviation (AARD%) and a correlation coefficient (R2) of 1.95 and 0.9981, respectively, were in good agreement with the experimental CO2 loading data in comparison with other models.
