Abstracts: Freeze Crystallization In general, with thousands of organic compounds to choose from, freeze crystallization is especially interesting for the separation of isomers, azeotropes and other close boiling compounds, temperature sensitive substances, and all applications where high purity products are required. Freeze crystallization is a well-known purification technique. A single crystallization step is all that is necessary to produce 100% pure crystals in eutectic systems. Freeze Crystallization is economical than other mass transfer unit operations like Distillation, Liquid liquid extraction. Energy consumption is lower. Quality of the product is relatively higher than other operations mentioned above.
