Abstract
Optimization of batch crystallization is studied with tight constraints on the maximum rate of change of batch temperature or maximum rate of evaporation. It is observed that under tight constraints, the constraint has the greatest effect on the shape of the batch trajectory. Three crystallization systems are simulated for different values of the batch time and crystal yield. The resulting temperature or evaporation rate trajectories are plotted in dimensionless coordinates and fit to an empirical equation. The empirical equation performs similar to other convex trajectories recommended in the literature and much better than the linear trajectory. ? 2017 IEEE.
