Résumé

To simulate cyclohexane oxidation reactors using a dynamic model linking kinetics, thermodynamics and hydrodynamics, the acquisition and modeling of vapor-liquid equilibria of the key components, under the process conditions, are essential. In this work, the vapor-liquid equilibria of the cyclohexane. +. cyclohexanol system were determined at temperatures 424, 444, 464 and 484. K. The measurements were carried out using an apparatus based on the " static-analytic" method, with two ROLSI™ pneumatic capillary samplers. The generated data are successfully correlated using two equations of state, the Peng-Robinson (PR) and the Perturbed-Chain Statistical Association Fluid Theory (PC-SAFT). A comparison of model performances reveals the former being better in data representation, while the latter has a broader applicability over larger range of temperatures.
