Rapid Prediction of CO 2 Solubility in Aqueous Solutions of DEA and MDEA

In the present work, a simple‐to‐use correlation is developed to predict the solubility of CO 2 in aqueous solutions of DEA and MDEA as a function of the reduced partial pressure and temperature. Using the interaction parameters generated, the model is applied to correlate the CO 2 loading in different amine solutions. The results from the proposed correlation have been compared with the reported experimental data and it was found that there is a good agreement between the observed data and the model predictions over a wide range of operating conditions in aqueous solutions of both diethanolamine (DEA) and methyldiethanolamine (MDEA).
