In this paper, we proposed and used an electrolyte version of modified Peng- Robinson (emPR- CPA) equation of state to model solubility of H2S in N-methyldiethanolamine (MDEA) aqueous solution at different solution compositions, temperatures, pressures and acid gas loadings. For electrolyte part of the model, MSA theory together with the Born term was used. To model the system, ternary system was modeled using a reactive bubble point pressure calculation method. Results had good accuracy with acceptable Absolute Average Deviation percentage (AAD%) of 20.85. The AAD% showed that emPR- CPA is an efficient model to represent solubility of H2S in aqueous MDEA solutions.
