Crystallization
Crystallization is the best way to obtain purified products. The kind of crystallizer is often linked to the required crystal size.
DRAFT TUBE BAFFLES (DTB) CRYSTALLIZER
DTB crystallizers provide superior control over crystal size and characteristics. For superior control over particle size when excessive fine crystals are present, the DTB crystallizer has been proven highly effective.

FORCED CIRCULATION (FC) CRYSTALLIZER
The FC crystallizer is used for applications where high rates of evaporation are required. It is also used for scaling compounds, inverted solubility solutions and solution is of relatively high viscosity.

OSLO CRYSTALLIZER
The Oslo crystallizer also known as growth crystallizer is used for the production of large, coarse crystals.
The Oslo crystallizer work on de-supersaturation of the mother liquor through contact with the largest crystals present in the crystallization chamber. The smaller crystals are kept in suspension by a stirring device enabling the production of large crystals.

DRY CRYSTALLIZATION
The “dry crystallization” consist in a pipe reactor installed at the top of a prilling tower. Inside the pipe ammonia and acids are mixed to form crystals. Crystals size depends on residence time in the pipe which is adjustable. This technology can provide very small crystals
