Continuous cooling crystallization from solution

In this paper, a model was constructed in order to simulate the behaviour of slow growing crystals in high viscosity systems in a tower crystallizer. This type of crystallizer, ideally, is an application of the plug–flow concept. Plug–flow conditions are an advantage when a narrow crystal size distribution is the goal desired. The model was based on the following assumptions: steady state operation, no nucleation or growth rate dispersion, no breakage, size-dependent growth and settling of crystals. A simulation example for sucrose is presented although the model applies to other similar systems.
