WebCrystallisation is a separation technique that is used to separate a solid that has dissolved in a liquid and made a solution. The solution is warmed in an open container, allowing the solvent to evaporate, leaving a saturated solution. A solution that has as much solid dissolved in it as it can possibly contain is called a saturated solution. WebCrystallization takes place in the inner tube, while the coolant flows through the outer tube. The surface of the inner tube is kept free from solids by rotating scrapers. Armstrong Chemtec is a leading supplier of tubular crystallizers with a scraped heat exchanger.

Crystallization is the process by which solid forms, where the atoms or molecules are highly organized into a structure known as a crystal. Some ways by which crystals form are precipitating from a solution, freezing, or more rarely deposition directly from a gas.
