A crystallization process is a complex plant for the production of an industrial bulk product. One of the key paramaters for crystallization is the supersaturation.
Supersaturation is the temporary increase of concentration of the solute in the solvent, and is produced by evaporation, cooling, chemical reaction, salting out, etc.
The supersaturation is the driving force of crystallization. Proper control of supersaturation is of critical importance in achieving acceptable results in a precipitation step.
In sequence of treatments, crystallization surely is an important but by far not the only unit operation. The feedstream often has to be purified, filtered or mixed in order to allow for chemical reaction prior to crystallization.
After crystallization, the crystals have to be separated from the mother liquid, washed, dried and in particular cases other final treatements may be necessary. Storage and packing are often part of a crystallization plant.
