ABSTRACT

Isothermal vapor liquid equilibrium measurements of three binary systems, H2S + propane, H2S + n-butane, and H2S + n-pentane, have been performed with a static synthetic apparatus at low temperatures. The method of Barker has been implemented to determine the corresponding nonrandom two-liquid (NRTL) parameters and to calculate the liquid mole fractions. The results have been further used along with literature data to adjust binary interaction parameters of the Peng Robinson equation of state. Good agreement with Dechema values has been found.
