Distillation control scheme design using dynamic models

The stabilizer case study has demonstrated how the effects of different control strategies on the profitability of a given process can be generated directly from steady-state simulations. The methodology requires  

2 An accurate description of the expected disturbances to the process that will push the process away from its optimal profitability. 

It is these two parts that take the most time to develop when using the methodology the actual simulation runs are only a small part of the work. 

8 Distillation control scheme design using dynamic models 

As detailed above, the steady-state methodology can be used to screen a large number of candidate control schemes quickly and efficiently. However, it is desirable then to evaluate the candidate control schemes using a dynamic simulator to check the dynamic disturbance rejection capabilities of the alternative control schemes. A case study that demonstrates the application of this design scheme is available in the literature [16].
