Modèles de connaissance de la cristallisation de troisième jet en sucrerie de cannes Expérimentations et simulations

Abstract : This study deals with modeling the boiling third crystallization process, boiling C crystallization in cane sugar mill. Due to the complexity of physicochemical phenomena involved in the industrial boiling crystallization, it is necessary to develop several modelling approaches. By this way, the variability of these models leads to compare the various modeling suggested. We have focused our research on modeling various kinetics of physical phenomena contributing to the boiling C crystallization, through mathematical models. We have considered three kinetics that exist in solution: the nucleation rate, the growth rate and the agglomeration rate. We are proposing several boiling modeling, called “hybrid modeling strategies”, which are the combinations of neural networks and the prior knowledge. The neural networks' training is based on some industrial data, and the boiling C crystallization process modelling associates this systemic model to the prior knowledge. The various approaches presented do not exclude the classical modelling in boiling crystallization. For this reason, if we want to supervise the boiling crystallization process, several mathematical models are suggested through the population balances. This study is original, on one hand, by describing the boiling C crystallization, and on the other hand, by the identification of several modeling with industrial data. It is necessary to underline that there is a lack of literature data regarding the boiling C crystallization, and thus there are only few bibliographical references on the boiling C crystallization in cane sugar mill.
