Fig. 1 illustrates the principle of a conventional evaporative crystallization system. As the raw material liquid enters the crystallizer, it experiences a sharp pressure drop and is then heated by industrial steam. Once the solution reaches its bubble point, vigorous boiling ensues, leading to the formation of product crystals.
