CHNG2804: Chemical Engineering Thermodynamics

This is a core unit within the curriculum. Chemical Engineering requires an understanding of material and energy transformations and how these are driven by molecular interactions. The rate of such transformations is dependent on driving forces and resistances, and these need to be defined in terms of fundamental physical and chemical properties of systems. This course seeks to provide students with a sound basis of the thermodynamics of chemical systems, and how these, in turn, define limits of behaviour for such real systems. The thermodynamic basis for rate processes is explored, and the role of energy transfer processes in these highlighted, along with criteria for equilibrium and stability. Emphasis is placed on the prediction of physical properties of chemicalsystems in terms of state variables. The course delivery mechanism is problem-based, and examples from thermal and chemical processes will be considered, covering molecular to macro-systems scale. The course builds naturally from the second year first semester course in heat and mass transfer, and prepares students fundamentally for the third year course in design of chemical and biological processes, which deals fundamentally with reaction/separation systems, and considers phase and chemical equilibria.

At the completion of this unit, you should be able to:

  • LO1. Demonstrate the ability to prepare a scientific report and deliver an oral presentation focused on an engineering process of your choice, incorporating the fundamental principles of thermodynamics.
  • LO2. Estimate thermodynamic properties of non-reactive fluids by carrying out energy, entropy and exergy balances under steady, and non-steady conditions
  • LO3. Apply the concept of property interrelation of thermodynamic variables to predict state variables of chemical systems under ideal, and non-ideal conditions
  • LO4. Employ the concepts of mass, energy, and entropy balance, and property interrelations to predict state variables in turbine and refrigeration systems
  • LO5. Characterise systems that include a mixture of phases and different component species using equilibrium principles in engineering thermodynamics.
