Module overview

The heart of any chemical or biochemical process is often said to be the reactor and a sound understanding the unit’s performance is a pre-requisite for the process design. This module builds on the reaction kinetics knowledge from level 1 and applies it to the design of homogeneous reactors and bioreactors. The design equations of such reactors often results in differential equations which require the application of standard numerical methods and the application of Matlab facilitates such a solution.

Module aims

Allow students to develop a comprehensive understanding of the methodology of linking chemical kinetics with material and energy conservation in the design of idealised homogeneous chemical reactors, operating either in batch or continuous mode, and under either isothermal or non-isothermal conditions.

Introduce students to the analysis of non ideal flow and, using the Dankwerts flow model, show its effect on both an idealised reactor design and sampling.

Provide students with knowledge and experience of using standard numerical methods in order to solve complex engineering problems

Provide students with knowledge and experience of using Matlab and programming in order to solve complex engineering problems

Methods of Teaching / Learning

The learning and teaching strategy is designed to:

Carefully cover in lectures the necessary fundamental material and analytical techniques, and demonstrate concepts with appropriate (and where possible practical) examples
Allow students adequate time to practice the techniques using a large number of carefully selected tutorial problems.

The learning and teaching methods include:

Lectures                                3.4 hours per week for 11 weeks (average)
Tutorial/Problem Classes        3 hour per week for 10 weeks  (average)
Independent learning               8.5 hours per week for 11 weeks (average)

Assessment Strategy

The assessment strategy is designed to provide students with the opportunity to demonstrate

the full range of learning outcomes though the balanced mixture of lecture and tutorial/problem classes coupled with the carefully grades tutorial problems which reflect current industrial practice.

Thus, the summative assessment for this module consists of:

Examination – 50%, 2 hours (LO1, LO2, LO3, LO4, LO5, LO6, LO7)
Course Work – 25% (LO6, LO7)
Reactor Design Project – 25% (Group project)

Formative assessment and feedback

Two formative multiple choice tests will take place in the reaction engineering lectures followed by verbal feedback and open discussion during the lectures
