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.
After successfully completing this unit students should be able to:
* complete problems on heterogeneous catalytic reactors if they are supplied with global rate data;
* understand the essential features that control microorganism growth and design fermenters for batch and continuous cultivation to apply a reaction engineering analysis to the controlled growth of microorganisms in biological reactors;
* to use global or homogenous kinetic expressions to formulate material and energy balances for batch CSTR and plug flow reactors that exhibit ideal behaviour with reversible and multiple reaction steps.
Analysis and problem solving (taught/facilitated and assessed).
Basic reactor designs: batch, CSTR, plug flow; application of stoichiometric tables; chemical equilibrium; definition of reaction rate, elementary reactions and temperature dependence; mass and energy balances developed for ideal batch, CSTR, plug flow reactors; ideal batch reactor: constant volume, variable volumes, variable temperature and pressure; expansion factor, irreversible and reversible reactions; performance comparison between batch, CSTR, plug flow; optimisation: multiple reaction; parallel, series, series-parallel, selectivity and yield, optimum temperature, isothermal, adiabatic and non-adiabatic modes of operation, multiple reactions temperature effects; 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.
