10.1 Fundamentals of crystallization and precipitation
2 min read•july 24, 2024
Crystallization and precipitation are key separation processes in chemical engineering. These techniques form solid particles from liquid solutions, but differ in speed, product purity, and particle characteristics. Understanding their fundamentals is crucial for optimizing industrial separations and product quality.
Factors like , pressure, and pH influence solubility, driving crystallization and precipitation. The metastable zone is vital for controlled . Key steps include generating , , crystal growth, agglomeration, and product recovery. Mastering these concepts enables efficient separations across industries.

Crystallization forms solid crystals from homogeneous solution in supersaturated conditions purifies and separates solids (sugar refining)
Precipitation rapidly forms solid phase from liquid solution through chemical reaction yields smaller, less organized particles (water treatment)
Key differences:
Crystallization slower than precipitation creates larger, more uniform crystals
Crystallization typically produces purer products than precipitation
Factors affecting solubility
Temperature increases solubility for most solids some exhibit inverse solubility (calcium carbonate)
Pressure primarily affects gas solubility in liquids increases with higher pressure (carbonated beverages)
