Melt crystallization technology introduction

Melting crystallizer has not been widely used in China at present so there is no more engineering experience for reference. Therefore, our design of melt crystallizer is based on the melt crystallization process of the Crystallization Process Research Institute of Tianjin University of Science and Technology. Please click on the melt crystallization industrial application statistics, or the website of crystallization technology blog to obtain the information of relevant melt crystallization process development and equipment.


Applied Range

Melt crystallizer is widely used in the production of chemical intermediates, pharmaceutical intermediates and high purity crystal products of biochemical products.

Product Classification

It can be divided into two types: high-efficiency static melt crystallizer and dynamic tower falling film melting crystallizer

Material

Carbon steel, stainless steel and special metal materials.

Advantages

①It is featured by strong practicability, and different types of equipments are selected according to different technological requirements

②Low investment cost, the price is only 1/5-1/10 of the same price abroad; 1/2-1/6 of the domestic price

③Operation flexibility, automatic control and manual operation are both ok.

④compact and reasonable

⑤good application effect and low crystallization loss

⑥It makes some complex processes become especially simple

Disadvantages

The structure of the mold is a little more complicated than that of the distillation column. It needs Sweating, washing, etc. The process is complex and difficult to be continuous.

Compared with other heat separation units, melt crystallizer has the following advantages:

Firstly, it is characteristiced by high selectivity, low energy consumption, low operating temperature, no solvent, no waste liquid, no gas phase. Compared with distillation, it has many advantages, such as low operating temperature and small energy consumption. Besides, Waste heat from other operating units in the plant can be utilized. Because most of the organic compounds’ melting point is in the range of the waste heat in the factory.

Compared with solution crystallization, melt crystallization avoids the post treatment process of the solvent without adding new solvent, and this advantage can often compensate for other shortcomings of the melt crystallization.

In Summary

Melt crystallizer deals with liquid substance, which requires a small size and a small amount of equipment, therefore needs less investment. However, if melting crystallization takes longer residence time, then this advantage is not obvious. During crystallization, no gas is produced, and leakage is easy to control. Moreover, the whole equipment can be closed and is more conducive to environmental safety. Molten crystallization does not require the addition of any substance, so no waste liquid or other chemical substance (solvent) is produced. The cost of solvent recovery often accounts for most of the cost of the crystallization process. For the non solid solution type system, the crystallization process has very high selectivity and the purity of the product can be as high as 100%.
