Module Overview

The heart of a chemical 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 covers both chemical kinetics of homogeneous systems and the design of reactors processing such systems.  The rate of reaction defined explicitly in terms of system volume combined material and energy balances permit the sizes of reactors processing homogeneous systems but with different idealised flow regimes can be determined.





Successful completion of Level HE1of Chemical and Bio-systems Engineering or the Chemical Engineering programmes.




Module Aims

To provide the student with:



·      a systematic understanding of homogeneous chemical reaction kinetics including both free radical and catalysed reactions.



·       a comprehensive understanding of the methodology of linking chemical kinetics with material and energy conservation in the design of idealised homogeneous chemical reactors operating both in batch and continuous modes and under both isothermally and non-isothermally conditions.



·       a superficial understanding of the analysis of non ideal flow and, using the Danckwerts flow model, a knowledge of its effect on an idealised reactor design and sampling   




Learning Outcomes

Upon successful completion of this module you will be able to:


·       generate both differential and integrated rate equations for homogeneous chemical reactions


·       correctly interpret experimental concentration-time data and from it propose appropriate kinetic equation


·       explain the operation of homogeneous Batch, CSTR and Plug Flow reactors and confidently propose the appropriate reactor for a specified duty


·       propose a design methodology and then correctly solve the volumetric design of homogeneous Batch, CSRT and plug flow reactors processing simple reversible and irreversible reactions operating under both isothermal and non-isothermal conditions


·       understand the complexity of reactor design and to recognise your own limitations.


·       explain the need for safe design and the responsibilities of the designer of chemical reactors
