A forced circulation crystallizer—also known as a circulating magma crystallizer or mixed suspension mixed product removal (MSMPR) crystallizer—consists of a body sized for vapor release with a liquid level high enough to enclose the growing crystals.

How does forced circulation crystallizer work?

Forced-circulation crystallizers, such as the one shown below, are evaporative crystallizers. They create a super-saturated solution by evaporating the solvent of a saturated solution. The solute of this supersaturated solution then cools, forming crystals.

What is forced crystallization?

FC Crystallizers

The average FC crystallizer evaporates solvent, thus increasing the supersaturation in the process liquor, and causing crystallization to occur. ... The evaporated solvent is conducted to the vacuum system, where it is condensed and removed.
