Abstract
In the analysis of crystallization systems, an important consideration in studying the factors influencing size distribution is the method of characterizing the distribution. In most design procedures currently in use, the size distribution is characterized by the mass of crystals in a given size range. This type of distribution is obtained easily from a screen analysis of the crystals. It is of little use, however, when the influence of nucleation rate on size distribution is under study. As it turns out, the nucleation kinetics is the primary factor limiting crystal size obtainable in any continuous crystallization process. It is, therefore, of considerable interest to have, an analytical approach which provides a method for characterizing the crystal distribution and which will, at the same time, facilitate the determination of nucleation effects on size distribution.
The basic ideas of the population balance are presented along with the use of the population balance in relating system parameters and crystallization kinetics with size distribution. The principles are illustrated in the context of classification and fines destruction systems. Example problems are provided for the reader.
