A generic multi-dimensional modeling framework for studying batch cooling crystallization processes under generated operational policies is presented. The generic nature of the modeling allows the study of a wide range of chemical systems under different operational scenarios, enabling thereby, the analysis of various crystallization operations and conditions. Furthermore, a systematic procedure for generating operational policies through available analytical crystal size distribution (CSD) estimators has been developed and verified for achieving targeted CSD consistently. The application of the model-based framework is highlighted for batch cooling crystallization of potassium dihydrogen phosphate (KDP) in two-dimensions, while the use of the analytical estimator is demonstrated for a potassium dichromate case study to achieve a target CSD.
