Using a mathematical model, from the literature, for the potassium sulphate crystallization, a computer programme was elaborated, aiming to optimize the operation of batch crystallizers through the minimization of the formed crystals number. Owing to the simplifications imposed by the numerical calculation a semnificative reduction of the crystals number was not obtained, comparatively with the constant supersaturation crystallization process, considered as a standard mode of operation. However, the model pointed out the direction for further process improving. Through systematical search, by generating different continuously diminishing functions for the supersaturation value, operating policies were founded, conducting to the reduction of the number of crystals formed in the process.
