The reaction is highly exothermic, giving the user the opportunity to explore the difficulty in tuning a controller on an inherently unstable process.
The product quality is measured by a discontinuous analyser, to illustrate the difficulties this produces when derivative action is used.
The reactor further generates a large process hold-up, permitting the user to apply a number of deadtime compensation techniques in order to control product quality. Each can be tested with setpoint and load changes. The importance of model accuracy is demonstrated.
