Isothermal Vapor−Liquid Equilibrium Data and Thermodynamic Modeling for Binary Systems of Perfluorobutane (R610) + (Methane or Hydrogen Sulfide) at (293, 313, and 333) K

Abstract : Isothermal vapor−liquid equilibrium data for binary system comprising perfluorobutane (R610) with methane (CH4) or hydrogen sulfide (H2S) were measured at isothermal conditions of approximately (293, 313, and 333) K, and pressures up to 9.837 MPa. The data were measured using a “static-analytic” apparatus equipped with a mobile pneumatic capillary sampler. The experimental data were correlated via the direct method using two sets of thermodynamic models. The Peng−Robinson equation of state incorporating the Mathias−Copeman α function, with the Wong−Sandler mixing rule utilizing the nonrandom two-liquid activity coefficient model, was used for the correlation of the CH4 + C4F10 system, while the Soave−Redlich−Kwong equation of state incorporating the Mathias−Copeman α function, with the modified Huron−Vidal first-order mixing rule utilizing the nonrandom two-liquid activity coefficient model was used for the H2S + C4F10 system.
