Main Crystallization Processes
The main factors influencing solubility are, as we saw above:
- Concentration
- Temperature
So we may identify two main families of crystallization processes:
- Cooling crystallization
- Evaporative crystallization
This division is not really clear-cut, since hybrid systems exist, where cooling is performed through evaporation, thus obtaining at the same time a concentration of the solution.
A crystallization process often referred to in chemical engineering is the fractional crystallization. This is not a different process, rather a special application of one (or both) of the above.

Famous quotes containing the words main and/or processes:
“So long as war is the main business of nations, temporary despotism—despotism during the campaign—is indispensable.”
—Walter Bagehot (1826–1877)
“The vast results obtained by Science are won by no mystical faculties, by no mental processes other than those which are practiced by every one of us, in the humblest and meanest affairs of life. A detective policeman discovers a burglar from the marks made by his shoe, by a mental process identical with that by which Cuvier restored the extinct animals of Montmartre from fragments of their bones.”
—Thomas Henry Huxley (1825–95)
