Modelling and simulation of the non-ideal mixing behaviour of the crystallization stage in a sugar factory batch crystallizer

Abstract
A first principles model of a semi-batch crystallizer is proposed, taking into account the non-ideal mixing behaviour of the process. For this purpose, a two- compartment model is developed in order to predict the evolution of the variables related to the sugar crystallization in a more realistic way. The model is based on mass and energy balance equations. It also includes population balance equations to keep track of the sugar crystal size distribution (CSD). Finally, the model is adjusted and validated with real factory data.
