REACTION ENGINEERING - 2023/4
Module code: ENG2129
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.

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:
- Class Test – 20% (LO1, LO2, LO3, LO4)
- Examination – 80%, 2 hours (LO1, LO2, LO3, LO4, LO5, LO6)
Formative assessment and feedback
- Weekly verbal feedback will be given during tutorial classes.
- Written feedback on the Class Test
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.

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
- Tutorial/Problem Classes
- Independent and guided learning
Indicated Lecture Hours (which may also include seminars, tutorials, workshops and other contact time) are approximate and may include in-class tests where one or more of these are an assessment on the module. In-class tests are scheduled/organised separately to taught content and will be published on to student personal timetables, where they apply to taken modules, as soon as they are finalised by central administration. This will usually be after the initial publication of the teaching timetable for the relevant semester.
