Abstract

Abstract: In this work a generic multi-compartment, multi-zone population balance model (PBM) is developed which allows predicting the process dynamics of particle formation in a horizontal fluidized bed. It focuses on the particle size distribution (PSD) which is an important quality parameter in solids process industry. It is influenced by different factors, e.g. apparatus design (weir and nozzle assembly) and process conditions (mass flow rate), respectively. In this study the apparatus design by an over and under flow weir configuration, used separately or in combination, is investigated to obtain the product properties at the outlet of the apparatus. Simulation results show how characteristic product data depend on the process conditions and apparatus design. The obtained trends can then be used for an inverse apparatus design of horizontal fluidized beds to obtain particles with desired properties.
