| Course description | Chemical Engineering is concerned with the design and operation of chemical processes on an industrial scale. Such chemical processes have traditionally concentrated on bulk inorganic chemicals (e.g. fertilisers), polymers, solvents, dyestuffs and explosives, but are increasingly including speciality chemicals, pharmaceuticals, food and biological systems. This course gives an introduction to the design of such industrial processes, including chemical reactions and reactor design, energetics of chemical processes, determination of material and thermal flows within processes, phase equilibria and separation processes. In so doing, it covers many of the principles involved in taking chemical processes from the bench/laboratory research scale to the construction and operation of modern commercial chemical plants. |

Summary of Intended Learning Outcomes
On successfully completing this course, students will be able to:
1. Draw and interpret simple process flow sheets and block flow diagrams, sequence separations and calculate economic potential.
2. Make simple design choices based on system constraints.
3. Mark the appropriate balance boundaries on a process flow sheet.
4. Formulate and solve algebraically material balances for processes involving reactors, separators, recycle and purge.
5. Solve problems involving thermal conduction across a stratified medium, convection in laminar or turbulent flow and radiation in simple geometries.
6. Use dimensionless correlations to predict heat transfer coefficients.
7. Determine heat duties and heat transfer area required in countercurrent, cocurrent and shell and tube heat exchangers, allowing for fouling of the heat transfer surface.
8. Describe quantitatively the kinetics of simple reactions.
9. Design and compare the performance of different types of reactor.
10. Perform a simple energy balance around a reactor.
11. Describe a range of standard separation techniques.
12. Interpret simple phase diagrams, including identification and explanation of the triple and critical points.
13. Obtain vapour pressures, by empirical equation or phase diagram, and describe the state of matter at a given temperature and pressure.
14. Predict the pressure within a storage vessel and choose an operating temperature for a vaporiser or condenser.
15. Relate partial pressures to vapour pressure when more than one gas is present and determine dew point for a gas stream containing one condensable component and the quantity of liquid condensing for a given temperature change.
16. Use Raoult&©s Law to relate phase composition to temperature and pressure of a two-component ideal mixture.
17. Design a simple flash vessel and comment on its limitations.
18. Determine graphically the minimum number of stages required for binary distillation.
19. Use the basic functions of Excel and design and document good spreadsheets.
20. Create and format graphs and insert trendlines.
21. Use goal seek and solver for chemical engineering applications.
22. Prepare and conduct laboratory work; gather and analyse data, using logarithmic plots and dimensionless numbers.
23. Communicate findings through short and full laboratory reports.
24. Solve problems within a group.

| Syllabus |
This course comprises 4 lectures on process synthesis, 5 lectures on mass balances, 4 lectures on heat transfer, 4 lectures on reactors, 8 lectures on separations and 4 lectures on chemical engineering in practice. There are 11 tutorials to support these lectures. In addition, students attend 5 laboratory sessions (one of which involves a safety audit and introduction to error analysis) and 3 computing sessions. A practice examination is held in one lecture slot and feedback on this provided both orally and in written form.
