文摘

A solved design problem of how to deal quantitatively with crystallization problems below the eutectic temperature is presented. This problem serves as an excellent pedagogic complement to undergraduate students of chemical engineering since it is solved by means of a solubility diagram. It also promises novelty and environmental improvement to students, exposing them to eutectic freeze crystallization (EFC) technology, which is gaining momentum to be implemented in waste water treatment. By means of mass balances together with the solubility diagram, the proposed problem involving two crystallizers and a recycle stream is solved, and in so doing teaches students about the possible application of EFC in the treatment of brines.
