Temperature, stirrer speed and other process inputs determine the rate of physical phenomena like agglomeration and growth. This study aims to develop a dynamic model structure that describes the physical phenomena in the crystallization process. The population balance equation is the basis of the model structure. Simple kinetic relations and the concentration balance are coupled to the population balance. The high resolution finite volume scheme is applied as the numerical solution method to solve the population balance equation. The dynamic model is validated with experimental results from an adipic acid crystallizer. Gathering the experimental results is a large part of this study. The process inputs of the crystallizer are changed to see the effect on the crystal size distribution (CSD). A change in the temperature seems to have the largest influence on the CSD. But the recirculation rate is the most effective process input to vary. The experimental results were used to validate the model structure. The model results shows that the model can simulate the measured mean crystal size accurately. Improvements on the kinetic relations have to be made to also simulate the complete CSD.
