Evaporation and Crystallization Plant
In the field of mass crystallization from solutions , we are expertise. We design and manufacture all basic types of crystallizers for the crystallization from solutions, such as the forced circulation (FC) evaporation crystallizer , the turbulence (DTB) evaporation crystallizer, and the fluidized bed (OSLO) evaporation crystallizer.
We are in a unique position to address the special needs of clients, depending on the required product crystal quality and size. In addition to the center piece of a crystallization system, the crystallizer, we offers clients the supply of optimized peripheral equipment, such as the preconcentration ( multiple effects, TVR, MVR) .
Type of Crystallizer:
1. Forced Circulation (FC) Crystallizer
The forced circulation (FC) crystallizer is the most common type of crystallizer in the industry. The average FC crystallizer evaporates solvent , thus increasing the supersaturation in the process liquor, and causing crystallization to occur. Most conventional FC units operate under vacuum, or a slight super atmospheric pressure. The FC consists of four basic components: the crystallizer vessel, which provides most of the volume dictated by the residence time requirements, the circulating pump, which provides the mixing energy, the heat exchanger, which supplies ernergy to the crystallizer ( in a typical evaporative crystallization operation), and the vacuum equipment, which handles the vapours generated in the crystallizer.
Slurry from the crystallizer vessel is circulated, in plug flow fashion, through the heat exchanger, and returned to the crystallizer vessel again, where its supersaturation is relieved by deposition of material on the crystals present in the slurry. The supersaturation is controlled so as to avoid spontaneous nucleation by sufficient circulation capacity. The evaporated solvent is conducted to the vacuum system, where it is condensed and removed.
The FC crystallizer is used for general, simple crystallization operations, where large crystal size is not a requirement. The FC design aim to protect the crystal size from reduction from the crystallizer environment, but has no features to aggressively increase the crystal size.
