Suspension Crystallization
Suspension crystallization hits high purity in one step.
Besides static and falling film, suspension crystallization is an industrially used melt crystallization technology. The specific advantages of this technology include a compact layout, high purity in one step, low energy consumption, and low installation costs.
Process
The advantages of suspension crystallization must be balanced against a higher mechanical complexity when compared with the layertechnologies.
The process can be divided in two blocks:
The advantages of suspension crystallization must be balanced against a higher mechanical complexity when compared with the layertechnologies.
The process can be divided in two blocks:
- Crystallization: production of the crystals.
This block consists of at least one scraped surface crystallizer for removal of the crystallization heat, and a growth vessel where the produced crystals have time to grow to a separable size. - Separation: separation of the crystals from the mother liquor.
This block consists of at least one wash column with peripherals such as a melt loop with a heat exchanger to melt the crystals.
