“…Finally, to investigate whether the PC-SAFT EoS provides good accuracy for multicomponent systems with only binary information, this model was applied to the modeling of the vapor-liquid equilibrium data for 43 multicomponent mixtures containing hydrocarbon (methane, ethane, propane, n-pentane, n-heptane, and n-decane) and nonhydrocarbon (nitrogen, carbon dioxide, and hydrogen sulfide) components, studied experimentally by Yarborough, 36 and the three-phase vapor-liquid-liquid equilibrium data of a natural gas system rich in nitrogen, reported by Stroud et al 7 The results of the modeling obtained for these systems indicate that the PC-SAFT EoS can be used with confidence to predict the phase behavior of multicomponent systems by using interaction parameters obtained only from experimental binary vapor-liquid equilibrium data.…”
