Excess enthalpies of the binary system methane-hydrogen sulfide by flow calorimetry

Enthalpies of mixing for the binary gaseous system methane-hydrogen sulfide were measured by an isothermal flow calorimeter at temperatures of 293.15, 305.15, and 313.15 K. For each isotherm, the measurements were made at pressures of 0.507, 1.013, and 1.520 MPa (5, 10, and 15 atm, respectively). The experimental results were compared with those predicted from the equation of state of Benedict-Webb-Rubin and Redlich-Kwong and the Redlich-Kwong equation with the modifications proposed by Jacoby and Robinson.
