Abstract / Description:In industrial crystallization, fines dissolution is used to improve crystalsize distribution (CSD) properties. Intense fines dissolution may lead to undesirable oscillations. Therefore, a controller design based on a population balance model is proposed. A late lumping approach is used where the controller design is based on an irrational transfer function resulting from the linearized population balance. The resulting irrational controller transfer function is then approximated by a rational one. The effectiveness of the controller is demonstrated in simulations. The proposed feedback control enables the use of high fines dissolution rates and hence the improvement of CSD properties.
