Solubility of Hydrogen Sulfide in Ethanediol, 1,2-Propanediol, 1-Propanol, and 2-Propanol: Experimental Measurement and Modeling
The solubility of hydrogen sulfide in 1,2-ethanediol, 1-propanol, 2-propanol, and 1,2-propanediol were experimentally measured. Gas concentrations were systematically measured by isochoric saturation method at temperatures from (303.15 to 353.15) K and total pressure from vapor pressure of solvent up to about 1.5 MPa. Results show that H2S dissolves in mentioned organic solvents in order 2-propanol similar to 1-propanol > 1,2 -propanediol > 1,2-ethanediol. The experimental data were correlated by using (1) the Krichevsky-Ilinskaya (KI) equation and (2) a generic Redlich-Kwong (GRK) cubic equation of state.
