Resum: | Phase equilibria for systems that present different types of azeotropy have been analyzed by using the dimensionless Gibbs energy of mixing (gM) for the liquid and vapor phases along with both the common tangent criterion and the phase stability test. First, the gM,L function for the liquid phase and its derivatives have been analyzed to obtain the boundary function between the homogeneous (L) and heterogeneous (LLE) regions as a function of the parameters for different activity coefficient models. Next, the excess Gibbs free energies and their first derivatives for the liquid and vapor phases have been analyzed to determine the mathematical conditions and the limits of different types of azeotropy (VLE and VLLE) and the possible combinations of two azeotropes in the same binary system. Finally, as a result of the combination of all this information, azeotropy and miscibility maps have been obtained as a function of the parameter values for Margules, van Laar, Wilson, and NRTL activity coefficient models. |
