RESUMO

This work represents a contribution to the synthesis of azeotropic distillation process, that is used to the separation of non-idealliquid mixtures, with the modelling of Steady-State Three-Phase Azeotropic Distillation Column. The following developments were carried out in this thesis: . Modelling and Simulation of Three-Phase Flash: development of the modelling and simulation of Three-Phase Flash to multicomponent systems, at fixed temperature and pressure, with liquid-liquid, liquid-vapor, liquid-liquid-vapor equilibrium calculations and multiphase bubbIe point calcuIations. This methodology is applicable in the thermodynamic characterization of the multicomponent systems through equilibrium surfaces, being totally independent of the initial estimates suppIy; . Methodology of Calculation of Heterogeneous and Homogeneous Azeotropes for MuIticomponent Systems: development of a new methodology of azeotropes calculations to multicomponents systems, with homogeneous and heterogeneous cases, independently of initial estimates supply. This tool is. very important for choosing adequate separation processes, especially to guide the choice of solvents to the azeotropic distillation application; . Modelling and Simulation of Azeotropic Distillation Columns: development of the modelling and simulation of the azeotropic distillation columns applicabIe to multicomponent systems separation, enabling the liquid-liquid-vapor equilibrium calculation in the internal stages of the column. The program presents a methodology to generation of estimates to the profiles of the interest variables and identification of the liquid-liquid and liquid-liquid-vapor equilibrium regions through commercial simulators
