ABSTRACT
In this work, isothermal vapor-liquid equilibrium (VLE) for the ethane + 1-propanol and propane + 1-propanol systems were measured in an apparatus based on the static-analytic method. VLE data and the critical point for the ethane + 1-propanol system were measured at (317.59, 324.51, and 348.68) K. Upper critical end point, lower critical end point, and liquid-liquid-vapor locus were also obtained. For the propane + 1-propanol system, equilibrium measurements were performed at (318.30, 324.31, and 348.93) K. Experimental VLE data were correlated with the Peng-Robinson equation of state using the classical and the Wong-Sandler mixing rules. A better representation of the phase behavior was obtained using the Wong-Sandler mixing rule.
