Mass and Population Balance in a Batch Crystallizer

The mass balance in a batch crystallizer is given in Equation 9.12 and has two terms only. Concentration in the crystallizer will change with the mass deposited onto the crystals and by evaporation of solvent  

Neglecting agglomeration and breakage, the population of particles in a batch crystallizer develops overtime simply by the growth of the particles (Equation 9.13)  

The distribution of particle size will vary with agglomeration and breakage processes, which will occur in any type of crystallizer (cf Chapter 4).
