文摘

An electrolyte mHKM-CPA equation of state is developed for solubility calculation of acid gases in alkanolamines. Using the present EoS, VLE calculation is carried out for CO2 solubility in aqueous MDEA systems. The results of AAD % was 12.14 for the CO2-MDEA-H2O system. The results are given in wide ranges of temperature, pressure, acid gas loading, and amine concentration.
