4. Oversaturation control

4.1 Controlling the speed of supersaturation creation

In this section, crystallization by simple cooling in a batch reactor is taken as an example, but the same principles prevail for other types of supersaturation creation. Referring to the diagram in figure 6 , rapid cooling of the solution inevitably leads to reaching the supersaturation limit and producing uncontrolled spontaneous nucleation waves. The very large number of nuclei then obtained, leads to a limitation of the final size of the crystals,...
