Abstract
The solubility of hydrogen sulfide (H2S) in N-methylimidazole (NMI) and gamma-butyrolactone (GBL) were experimentally measured. Gas concentrations were systematically measured by isochoric saturation method at temperatures from (303.15 to 353.15) K and pressure from vapour pressure of solvent up to about 1.2 MPa, in all experiments mole fraction of dissolved gas has been measured with uncertainty order of 10−3. In order to construct a GA-artificial neural network (ANN)-based model, the H2S solubility, molality and total pressure were selected for the output. The precision of the GA is compared with experimental data and also with thermodynamic modelling approach in which Peng-Robinson-Stryjek-Vera (PRSV) cubic equation of state with Panagiotopoulos-Reid combining rule has been chosen for this purpose.
