Overview
The course begins with an introduction to process modelling incorporating a revision of essential chemical engineering thermodynamics. The ideal gas law and equations for the computation of process heat/work requirements for isochoric, isobaric and isothermal processes are briefly revised. Adiabatic and polytropic processes are also treated. Advanced concepts including virial and cubic EOS are introduced.
The P-V and P-T phase diagrams, as well as the thermodymanic T-S, H-S, P-H diagrams for a pure substance are introduced together with the terms 'reduced pressure' and 'reduced temperature'. The isothermal compressibility and volume expansivity are discussed for liquids. Heat effects in terms of latent heats, standard heats of reaction and formation are introduced.
Vapour pressure and the Antoine Equation are treated allowing two-component vapour-liquid equilibrium to be discussed in terms of Raoult's law and modified Raoult's law.
PVT relations for real gas mixtures are addressed; Dalton's & Amagat's laws modified by compressibility and the pseudo-critical method employing Kay's law are covered.
Residual properties and the experimental determination of thermodynamic properties are addressed.
Solution thermodynamics concepts including fugacity and excess properties are introduced together with property changes of mixing. Activity models are discussed.
Chemical reaction equilibria are treated including an evaluation of equilibrium constants and their relation to composition. The phase rule for reacting systems is discussed. Multireaction equilibria are introduced.
Structure
30 one-hour lectures, 10 one-hour tutorials and 3 three-hour laboratories in total.
Assessment
1st Attempt: 1 three-hour written examination paper (80%), and continuous assessment (20%).
Resit: 1 three-hour written examination paper (100%).
Feedback
a) Students can receive feedback on their progress with the Course on request at the weekly tutorial/feedback sessions.
b) Students are given feedback through formal marking and return of laboratory reports.
c) There will be a test exam at the end of the teaching session. The test exam will be marked (but is not part of the continuous assessment) and the test exam paper questions will be discussed in the Revision week.
d) Students requesting feedback on their exam performance should make an appointment within 4 weeks of the publication of the exam results.
