Abstract
This paper presents a dynamic model of a bubble column reactor with particle formation, accomplished by adopting a hybrid CFD-reaction engineering approach. CFD is employed for estimating the hydrodynamics and is based on the two-phase Eulerian-Eulerian viewpoint. The reaction engineering model links the penetration theory to a population balance that includes particle formation and growth with the aim of predicting the average particle size. The model is then applied to the precipitation of CaCO 3 via CO 2 absorption into Ca(OH) 2aq in a draft tube bubble column and draws insight into the phenomena underlying the crystal size evolution. © 2001 Elsevier Science Ltd.
