- Compact layout
- High purity in one step
- Low energy consumption
- Low installation costs
Suspension crystallization hits high purity in one step
- Organic and inorganic chemicals at high purities
- Carboxylic acids
- Aromatic isomers
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.
For certain applications, delivery of a skid-mounted unit may be an option.
