Abstract
This paper deals with the modelling of the precipitation of decahydrated neodymium oxalate from experimental data. The model takes into account the kinetic laws of primary nucleation, crystal growth and agglomeration and is based on two population balances, one for the crystallites and one for the particles. The population of particles is solved using a quadrature moment approach and then reconstructed by splines using an algorithm proposed by Chebyshev. The particle sizes predicted, at steady state for different experimental conditions, are in very good agreement with the experimental measurements.
