Oslo Crystallizer
Oslo Type Crystallizers are facilities developed for the production of coarse-grained crystals, the design of which dates back many years. The supersaturation of the mother solution is eliminated by contacting the coarse crystals in the crystallization main body. Most of the crystals are suspended by a circulation line, thereby producing coarse crystals with narrow size distribution.
The classifier crystallization section is the lower part of the crystallizer unit. The upper part is the liquor-steam separation area where supersaturation is developed by removing the solvent (water for most applications). The slightly supersaturated liquor flows down through a central tube and the supersaturation is removed by contact with the fluidized crystal bed.
The operating costs of the Oslo type crystallizer unit are much lower than other types when coarse crystals are required. Since the crystals are not in contact with any mixer, the amount of fines to be redissolved and therefore the energy requirement is lower. The Oslo type crystallizer allows long production cycles between wash cycles.
Advantages;
- Operating costs are much lower than other types of crystallizer
- Provides the opportunity to work continuously with low maintenance periods
- Allows long production cycles between wash cycles.
