Resumen:
Chemical engineering science has recognized the necessity of integrating
process design and control; however, few steps have been taken in this direction in polymer
science. In this work, a Mixed-Integer Dynamic Optimization approach is used for the
simultaneous design and control of a styrene polymerization reactor. Our goal is to design
the process and its control system in order to produce two polymer grades, which are
defined in terms of the number average molecular weight (Mn). The process design
involves reactor and initiator selection, and the two steady state operating points. The
control system consists of a feedforward-feedback control scheme, which is designed to
achieve optimal grade transition operation. The control system design includes optimal
pairings between controlled and manipulated variables and controllers tuning parameters
for PI feedback controllers, and the best trajectories of the feedforward controllers.
