In the chemical process industries GEA Messo AG crystallizers are decisive
to various processes including inorganic and organic products. The
crystallization systems are used for the treatment of the process liquor,
crystallization and separation of the final products. The unique
crystallization systems offer the flexibility to meet a wide range of
production requirements guaranteeing crystal size and purity for speciality
chemicals such as but not limited to adipic acid, citric acid, oxalic acid,
pentaaerythritol.
GEA Messo AG has supplied plants for various chemical
process industries with application of the following evaporation and
crystallization technologies:
- Multiple effect
- Thermal and mechanical vapour recompression
- Evaporative crystallization
- Vacuum cooling crystallization
In the field of industrial crystallization the control of the permissible
super saturation and the product specifications require the utilization of
crystallizers of different types. Crystallisers are of continuously operated
forced circulation type. They may be designed with internal or external
circulation, with or without baffle zones and with no, partial or total
classification.
