This paper discusses the importance of phase equilibrium modeling in heterogeneous azeotropic distillation. Seven ternary systems are used to examine the behavior of phase equilibria and its representation, through activity coefficient models. This work used vapor-liquid equilibrium, liquid-liquid equilibrium, vapor-liquid-liquid equilibrium, azeotropic points and residue curve data to pick up a model and its parameters with the goal that the election correlate the systems in a way that it is useful for conceptual design of heterogeneous azeotropic distillation. The paper presents results done with UNIQUAC. A procedure to obtain binary parameters is proposed. The procedure is validated through an azeotropic distillation conceptual design and its following optimization using a rigorous simulation.

The liquid-vapour equilibrium of the system methane-ethylene has been determined at 0, -42 , -78, -88 and -104° C over a wide range of pressures and the results are shown on a pressure-composition-temperature diagram and by a series of pressure-composition curves. The liquid-vapour equilibrium of the ternary system methane-ethane-ethylene has been determined at -104, -78 and 0° C. Values for the two binary systems methane-ethane and methane-ethylene and for the ternary system methane-ethane-ethylene are shown on a composite pressure-composition diagram.
