Armstrong Heaters. Armstrong's vertical bayonet design and direct electric vaporizers provide an on-demand supply of ammonia vapor for specific applications.
Melt crystallization and purification occur when a chemical mixture is cooled. The component within the mixture with the lowest solubility eventually starts to form crystals. Crystals have a standard structure, and impurities and other components do not fit within that structure. As a result, impurities assemble in the leftover liquid. Impurities that remain on the crystal surface can easily be removed. When this is done, it is possible to obtain products that reach 99.9 wt.% in a single process.
Very high purity process levels are possible with SoliQz melt crystallization technology. Tests using the SoliQz Hydraulic Wash Column (HWC), a continuous process, have been carried out on over 50 different chemical products, and HWCs are currently in use in multiple commercial plants throughout the world.
It is estimated that around 400 compounds can be easily handled using the melt crystallization process. The number increases each year as different companies and industries begin to utilize the benefits of melt crystallization. Some substances are more readily qualified than others, but with significant historical experience and a broad database of real applications, please reach out to us today to discuss if your product is suited for this process.
In many cases, especially for energy-saving, melt crystallization is considered a green alternative when compared to distillation. Melt crystallization happens at the melting point (solidification). Operating at low temperatures allows users to save on cost and energy, sometimes up to 90%. When compared to distillation, melt crystallization is known to achieve higher levels of purity with far fewer passes, hence saving time and utility costs.
