Abstract

The problem of minimizing the batch time of the copolymerization of acrylamide and quaternary ammonium cationic monomers at the industrial level is considered. An adjustable model of the optimal solution is used in the optimization. The model consists of two arcs: The first is isothermal and limited by heat removal constraint, whereas the second is adiabatic. The switching time between the two arcs is the only free parameter that is adapted on a run-to-run basis using batch-end measurements. A batch time reduction of 35% is observed after three batches.
