Objectives

- Understand the difference between ideal and real system behaviour, and apply thermodynamic relationships that describe and predict properties in real systems.
- Derive and transform thermodynamic relationships that predict thermodynamic properties e.g. specific enthalpies, entropy changes, equilibrium constants, free energies.
- Identify and predict quantitatively changes of thermodynamic quantities in ideal and real systems, including: heat and work; state functions (free energies, internal energy, enthalpy, entropy), in pure systems and in mixtures at system, phase and component level.
- Describe, analyse, model and predict energy flows in closed and open thermodynamic quantitatively in terms of the fundamental thermodynamic quantities.
- Use a range of equations of state to determine and predict overall system and partial properties in real and ideal systems (e.g., pressure, volume, temperature, concentration, mole fraction, fugacity, activity).
- Predict system changes (composition, pressures, exchanged heat and work, temperature) when physical and chemical transformations take place, by using chemical potentials, molar enthalpies/entropies of formation, and equilibrium constants.
- Model chemical and phase equilibria quantitatively in the context of separations and chemical processing.
- Use a range of equations of state to predict physical properties of systems, components and phases in ideal and real systems.
- Use databases of material properties to find relevant system, component and phase properties for thermodynamic calculations, including the use of steam tables.
- Apply thermodynamic principles in process design, identifying reasonable simplifying assumptions and predicting system properties when parameter values are uncertain.
- Use elementary programming skills to automate and/or implement numerical solutions in thermodynamic analysis and design.

Learning outcomes
- Understand the thermodynamic and transport properties of fluids and multiphase systems.
- Have a knowledge and understanding of basic mathematical models relevant to chemical engineering.
- Understand the principles of equilibrium and chemical thermodynamics, and application to phase behaviour, to systems with chemical reaction and to processes with heat and work transfer.
- Be familiar with the application and limitations of a range of modelling approaches including first-principles models, simple empirical correlations.
- Apply VBA-based digital techniques for solving chemical engineering problems.

Skills outcomes
- Ability to understand underlying physics associated with chemical thermodynamics.
- Transferable skills in linking fundamental theories to real world processes.
- Elementary VBA programming skills for solving numerical problems.
