Forced circulation crystallizer for evaporative crystallization

Crystallization of products with flat or inverse solubility in viscous media often faces challenges such as scaling and efficient operation. These challenges necessitate a solution capable of handling high mechanical energy inputs and maintaining consistent operation.

Efficiently handle crystallization in viscous media

The Forced Circulation Crystallizer from GEA, commonly used for evaporative crystallization, features a straightforward and robust design. It operates efficiently in processes where scaling is significant and large crystal production is not required. The system includes a mixed suspension, mixed product removal (MSMPR) crystallizer suitable for products with flat or inverse solubility. The elevated secondary nucleation rate limits crystal size to under 0.8 mm, while the installation can be single loop or double loop for large capacities. Key components include a heat exchanger for necessary thermal energy, axial-flow propeller pumps for circulation, and baffle zones for enhanced performance. Additional features such as internal or external demisters, integrated salt legs, and baffle zones ensure product purity and minimize down-time and scaling, making it ideal for various industries.

Benefits

  • Minimized scaling and downtime through advanced surface treatment
  • Suitable for viscous media with flat or inverse solubility curves
  • Limited crystal size for specific applications
  • High circulation rates due to axial-flow propeller pumps
  • Enhanced product purity with integrated baffle zones
