โœฆ Synopsis

The model-based experimental design of batch crystallizers is investigated. A dynamic programming formulation minimizes the volume of a confidence hyperellipsoid for the estimated nucleation and growth parameters over the supersaturation profile and the seed characteristics, namely, the crystal mass, mean size, and width of the seed distribution. It is shown that the accuracy of the parameter estimates can vary by several orders of magnitude depending on the seed characteristics, and that highly accurate estimation of nucleation and growth parameters can be obtained with as few as four batch experiments.

A network flow model is presented for synthesizing crystallization-based separations for multicomponent systems. The construction of the network flow is based on the identification of feasible thermodynamic states. The method allows consideration of seยฎeral operation temperatures, complex solid แŽ li

## Abstract Empirical and mechanistic experimental design methods are combined to construct partial models, which are, thus, used to design a process. The grid algorithm restricts the next experimental point to potential process optima, according to the confidence intervals around the optimal point
