Thermodynamic and GMDH Modeling of CO2 and H2S Solubility in Aqueous Sulfolane Solution

The solubility of hydrogen sulfide (H2S) and carbon dioxide (CO2) in mixed solvents were modeled using two approaches. The Gibbs excess energy of mixed solvents such as modified Pitzer as thermodynamic approach and GMDH as an artificial intelligence approaches which both have been adopted to analyze the reported experimental data in literature. The precision of the modified Pitzer and GMDH models are compared with each other and also with experimental data. The obtained results show that the modified Pitzer and GMDH have acceptable agreement with experimental reported data and also GMDH could be an acceptable alternative model for the modified Pitzer one.
