Witryna4. Is it true that melt crystallization is a green alternative to distillation? In most cases yes. Whereas the frequently used distillation method occurs at the boiling point of the substance, melt crystallization happens at the solidification (or melting) point. When operating at lower temperatures, you often save out on both energy and costs.
