Section 4.5.3: Exercise: Modelling the vaporiser with a control syste

The vaporiser model has no control system and will eventually either boil dry or go off the boil.

First add a proportional controller to regulate the holdup in the boiler (i.e. the level) at a setpoint of 0.8 kmol.
Then add a proportional controller to regulate the pressure at 1.5 bara.
Finally make the pressure a controller a PI controller.

Produce graphs of the level and pressure against time. Email the worksheet with graphs to us as an attachment.
