Abstract
A precipitation reaction in a stirred tank reactor working in semi-continuous mode is investigated using population balance equations and reduced moment approaches. The steady-state system is investigated for the occurence of oscillating behaviour in such a system. Nucleation and growth rates are initially taken from the literature. In this article it is shown that small non-linear changes in the nucleation and growth functions lead to strong changes of the region in the parameter space where oscillations of the particle size may occur. These observations may help to improve process analysis and design. The results show the important impact on processes dealing with the production of particular matter where the stability of working conditions has to be taken into account.
