Two dimensional population balance modelling of crystal growth behaviour under the influence of impurities

This short communication investigates the impact of impurity on crystal growth behaviour in terms of crystal shape distribution. A two dimensional population balance model is applied to study the crystal shape changing behaviour in cooling crystallisation producing β-form L-glutamic acid crystals, in the presence and without the presence of an additive, L-phenylalanine. The simulation results were verified in experiments using a 1-litre crystalliser for crystallisation of L-glutamic acid
