Closed loop controllability analysis of process designs: Application to distillation column design

摘要

This paper presents a new approach towards the integration of process design and control. The approach compares alternative process designs based on the optimal closed-loop performance in the presence of stochastic disturbances. The most important contribution is that a clear relation is established between the degrees of freedom in the process design and a closed loop performance measure. The approach is illustrated with a case-study of a distillation column.
