Phase equilibrium data for the hydrogen sulphide + methane system at temperatures from 186 to 313 K and pressures up to about 14 MPa

Abstract : Isothermal vapour–liquid equilibrium data have been measured for the methane–hydrogen sulphide (CH4 + H2S) binary system at five temperatures from 186.25 to 313.08 K, and pressures between 0.043 and 13.182 MPa. 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 CTP laboratory. The data were obtained with the following maximum expanded uncertainties (k = 2): u(T) = 0.06 K, u(P) = 0.006 MPa and the maximum uncertainty for compositions u(x, y) = 0.010 for molar compositions. The data have been satisfactorily represented with the classical Peng and Robinson equation of state.
