Module overview
The module will develop concepts related to reaction engineering and the design of reactors. Reaction engineering is at the heart of chemical engineering and one of the main requirements of chemical engineers is to design equipment where reactions take place in the most affordable, safe, and efficient way.
Aims and Objectives
Learning Outcomes
Knowledge and Understanding
Having successfully completed this module, you will be able to demonstrate knowledge and understanding of:
- Describe the various reactor types used in continuous and batch processing.
- Understand the principles of chemical reactions and how these are applied to the design of reactors;
- Explain the thermodynamic, equilibrium and kinetic aspects of chemical reactions that contribute to the energy and mass balances that must be considered in reactor design;
Subject Specific Practical Skills
Having successfully completed this module you will be able to:
- Apply concepts of safety, health and sustainability to complex systems that include chemical reactors;
- Collect and interpret kinetic data from experiments and relate these to scaled up reactors for applications at an industrial scale
Disciplinary Specific Learning Outcomes
Having successfully completed this module you will be able to:
- Consider and evaluate designs and select different types of reactors for different reactions; and reactors (batch and flow)
- Extend on the understanding of multiple reactions and how these can be manipulated to maximise products; including unsteady-state operation;
Subject Specific Intellectual and Research Skills
Having successfully completed this module you will be able to:
- Interpret heat effects in reactions and to be able to perform energy balances in reactions;
