Suspension-based process for pure crystal formation even in relatively impure melts.
Our proven wash column technology effectively separates the high value products from the impurities.
The GEA Melt Crystallization systems cool a crude liquid melt to create a driving force for the formation and growth of 100% pure crystals.
The suspension-based process distributes the crystal growth over a massive surface in the crystal suspension that provides the slow optimum growth rates needed to allow pure crystal formation even in relatively impure melts. By combining this extremely selective crystallization process with our proven wash column solid-liquid separation technology, an ultra-pure product can often be obtained after a single step.
Key features:
Melt crystallization provides an economic and energy-efficient alternative purification step in cases where standard distillation is unsuitable due to close boiling isomers, azeotropic systems, products that tend to polymerize, heat sensitive products or explosive substances.
Melt Crystallization plants can be found in thousands of installations around the globe serving to diverse industrial processes such as:
