Description: Aims:
To provide students with the ability to produce engineering designs of ideal reactors where the rate of reaction is controlled by chemical and biochemical reaction kinetics.

Learning Outcomes:
After successfully completing this unit students should be able to:
* carry out a reaction engineering analysis on the controlled growth of microorganisms and enzymes in biological reactors;
* perform material balances to derive general reactor design equations for different reactor types using appropriate reaction kinetics.
* perform energy balances for the different reactor types
* combine and apply material balances, rate laws, stoichiometry, and energy balances for optimal reactor design and operation.

Skills:
Analysis [T,F,A]
Problem solving [T,F,A]

Content:

* Introduction to biochemical techniques and their potential for transfer to large scale;
* Microorganism growth kinetics and kinetics of product formation;
* The effects of environmental variables such as pH and temperature on performance of bioreactors
* Isothermal reactors: Material balances and design equations for batch, continuous stirred tank, plug flow and packed bed reactors. Effect of volume changes on stoichiometry and design equations.
* Non-isothermal reactors: Energy balance for different reactor types, adiabatic temperature rise.
* Reactor networks: Comparison of reactor performances and series/parallel reactor systems
* Multiple reactions: series, parallel and reversible reactions, conditions for optimal reactor performance.
* Introduction to non-ideal reactors.
