Crystallization is often the best alternative when distillation is difficult, or even impossible. High purity products are manufactured from close boiling or azeotropic mixtures or components that are thermally unstable at their boiling point. The technology has proven to be the most reliable and environmentally friendly crystallization process, because crystals grow directly from the melt without the use of solvents. Selection of the most suitable technology is supported by bench and pilot scale testing. Typical applications are the purification of Monomers, Carboxylic acids, Tar chemicals, Waxes, Organic and inorganic chemicals at high purities.
