What is Static Melting Crystallizer?
The Static melting crystallizer makes a static molten mixture crystallization, sweating and melting on the surface of the Platecoil plates in stages, ultimately purifying one or more products from the mixture. lt is also called Platecoil solvent-free crystallizer because no solvent is used in the crystallization and purifying process. The Static melting crystallizer innovatively uses Platecoil plates as heat transfer elements and inherently has advantages that conventional separation technologies do not have. Static melting crystallizer uses a special heat exchange plate(Platecoil Plate) with heating medium or cooling medium, which is used for internal circulation heating or cooling process. The heat exchange plates are placed vertically in the crystallizer's cabinet, the heating or cooling medium slowly heats or cools the crystallizing mother liquid below the freezing point of molten substance. Finally, the crystallizing layer is formed on the heat exchange plate surface, it uses the "SWEATING" process to remove impurities and purified the crystals.
What is the Principle of Operation?
Static melting crystallizer is a way to purify and separate the target product from other components by using their different melting points (crystallization point), and to achieve crystallization and separation by cooling down to achieve the supersaturated state, The whole process is divided into three major steps which including crystallization, sweating and melting.
|
The molten mixture is slowly cooled by the heat transfer medium to below the crystallization point and crystals precipitate on the surface of the Platecoil plates, forming crystallization layers. Impurities are mainly present in the mother liquor and are discharged from the crystallizer. |
The crystallization layer can be purified by sweating (partial melting), i.e. slow heating to the melting point, then the encased and adherent impurities would be rinsed by melting product. Sweating is a key step in whole process. |
|
| After sweating, the temperature of the heat transfer medium is further increased to melt out all the crystallization layer and get the high purity liquid product. |
