The equilibrium of CO2 and carbamate concentration data for the absorption of CO2 in aqueous solutions of single and mixed amines was analyzed using the Deshmukh-Mather model. Data on CO2 loading in aqueous solutions of DEA and MDEA and their mixtures at various temperature (303-323 K) and CO2 partial pressure (0.09-100 kPa) together with carbamate concentrations in case of DEA and its mixtures with MDEA were fitted simultaneously to generate the different interaction parameters required to calculate the activity coefficients in the model. Using the generated interaction parameters, the model was applied to correlate the CO2 loading in solutions of DEA and MDEA and their mixtures reported in the literature as well as those obtained in our laboratory and was found to be able to give a good estimation of CO2 loading and carbamate concentration over a wide range of operating conditions in both single and mixed amine solutions.
