Thermodynamic and Artificial Intelligence Approaches of H2S Solubility in Some Imidazolium-Based Ionic Liquids

The solubility of hydrogen sulfide (H 2 S) in ionic liquids was modeled at various temperatures and partial gas pressures using two approaches. The first approach as a thermodynamic model, is a generic Redlich–Kwong (GRK) cubic EoS and the other is a Group method of data handling (GMDH) as an artifi...

Description
Summary:The solubility of hydrogen sulfide (H 2 S) in ionic liquids was modeled at various temperatures and partial gas pressures using two approaches. The first approach as a thermodynamic model, is a generic Redlich–Kwong (GRK) cubic EoS and the other is a Group method of data handling (GMDH) as an artificial intelligence approach. Results of modeling using both approaches were obtained by estimation of the percent relative deviation as well as the regression coefficients (R 2 ) and root mean square error. The GMDH model in this paper showed it is a reliable development to be an alternative method for the thermodynamic approach in modeling of H 2 S solubility data in ionic liquids in the extended ranges of pressure and temperatures.
