Isothermal vapour liquid equilibrium data have been measured for the binary hydrogen sulphide n-heptane system (H2S+n-C7) at five temperatures between 293.25 and 373.22 K, and pressures between 0.3979 and 6.8283MPa. The experimental method used in this work is of the static-analytic type, taking advantage of two pneumatic capillary samplers (RolsiTM, Armines patent) developed in the CEP/TEP laboratory. The data were obtained with uncertainties within +-0.015 K, +-0.0003MPa or +-0.0006MPa depending on the pressure transducer used, and +-3% for molar compositions. The isothermal P, x, y data are well represented with the Peng Robinson equation of state using the Mathias Copeman alpha function and the Wong Sandler mixing rules involving the NRTL model. The experimental data are compared to predictions from the PSRK group contribution equation of state and data found in the literature.
