Objectives

To introduce students to the concepts of classical thermodynamics, namely to provide methodologies to calculate thermodynamic properties and phase equilibria.
To introduce students to the concepts related to the use of mass and energy conservation principles, in order to solve mass and energy balances over chemical processes with and without chemical reactions. Perspective of these problems by general analysis of a case study.

Program

SOLUTION THERMODYNAMICS: Fundamental property relation. The concept of chemical potential and its relationship with phase equilibria. Ideal gas mixtures and Gibbs's theorem. Ideal solution model. Partial properties. Equations relating molar and partial molar properties. Gibbs-Duhem equation. Partial properties for binary mixtures. Relations among partial properties.
PHASE EQUILIBRIA: Application of the chemical potencial to phase equilibria. Fugacity and fugacity coefficient for pure species. Vapour-Liquid equilibrium for pure species in terms of fugacities. Fugacity for pure liquids. Fugacity and fugacity coefficient for species in solution. Calculation of fugacity coefficients using equations of state and generalized correlations. Raoult and Henry laws. Lewis-Randall's rule. Excess properties. Models for excess Gibbs energy. Equations for activity coefficients. Property changes of mixing. Vapor-Liquid equilibrium. Liquid-Liquid equilibrium. Solid-Liquid equilibrium.
APPLICATIONS OF PHASE EQUILIBRIA: bubble and dew temperatures and pressures calculations; calculations of compositions of equilibrium phases for non-ideal systems. Flash units- isothermal and adiabatic.
Chemical-Reaction Equilibria: equilibrium constants, equilibrium conversions for homogeneous and heterogeneous systems.
PREDICTION OF PROPERTIES: methodologies for the calculation and prediction of physical-chemical properties (group-contribution methods and corresponding states principle).
OPEN PROJECT: Analysis and study of a process - resolution of material and energy balances involving physical and chemical equilibria, and physical-chemical properties.
