Aims

At the end of the course the student’s attitude should move, away from: ‘All reactors are too complex to model’ or ‘All reactors are either perfectly mixed or plug flow’, towards: ‘It is possible to describe chemical reactors using models. However, all models have limitations. It is an engineer’s responsibility to be aware of these limitations and to choose a model which is of sufficient complexity to give an answer of the required accuracy’.

Teaching Rationale And Relationship

Lectures introduce theoretical concepts that will be practiced in tutorials. The case study provides an opportunity to apply knowledge gained together with knowledge from other modules, to solve a realistic problem.

Assessment Methods

The format of resits will be determined by the Board of Examiners

Assessment Rationale And Relationship

Examination assesses the knowledge and skills gained on closed problems where all necessary information is supplied. Case study assesses the skills obtained on open-ended problems where students must consider what information is needed to achieve a solution.
