Objectives

Background: Thermodynamics II requires and provides a solid knowledge of different methodologies for the calculation and prediction of physical and thermodynamic properties and phase equilibria (with and without reaction) for mixtures with industrial interest.

Specific aims: To develop the knowledge to calculate thermophysical properties of pure components and their mixtures, essential for process design, and to provide calculation methodologies for separation and reaction processes.

Percent distribution: scientific component - 60% technological component - 40%.

Learning outcomes and competences

Learning outcomes:

1. Technical Knowledges: nuclear knowledges on prediction of thermophysical properties of pure components and mixtures, with special emphasis on multiphase systems with application in the chemical, food and pharmaceutical industries.

2. Personal and Professional Aptitudes: resolution of engineering exercises - development of capacities to integrate previous concepts and knowledges.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Previous knowledge: Chemical Fundaments I and II, Calculus I, II and III, Algebra, Elements of Chemical Engineering and Thermodynamics I.

Program

SOLUTION THERMODYNAMICS: Fundamental property relation. Partial properties. Equations relating molar and partial molar properties. Gibbs-Duhem equation. Partial properties for binary mixtures. Relations among partial properties. The concept of chemical potential and its relationship with phase equilibria. Ideal gas mixtures and Gibbs's theorem. Ideal solution model.  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).
