SummaryChemical 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.
Course description 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.


The following subjects will be covered during the course:

Practice Exam Question

An exam-style question will be issued for completion during a lecture slot, to provide practice in exam technique. Feedback will be given on both the accuracy and the presentation of answers.


The computing element of Chemical Engineering 1 mainly consists of self study material available on Learn. There are three modules:

1. Excel basics. This module is completely self study with PowerPoint slides and worked examples in form of videos. A self test is available that allows to check if the learning outcomes of this module have been achieved.
2. Good spreadsheet design and plotting graphs. Self study material is also available on Learn. This module is further supported by a session in the computing lab where help is available for the exercises related to this module.
3. Use of goal seek and solver. In addition to the self study material available on WebCT, there will be a lecture on the use of goal seek and solver. Like the second module, it is further supported by a session in the computing lab where help is available for the exercises related to this module.

The computing element is assessed with a hand-in exercise which contributes 25 % to the coursework mark. There is a third computing lab session dedicated to the hand-in exercise. All computing lab sessions alternate with the laboratory session.
