Abstract

Eutectic freeze crystallization is a new separation process to produce pure ice and salt from concentrated salt solutions. For this new process, specialized crystallizers are being developed. A new, 2nd generation cooled disc column crystallizer (CDCC-2) with 150-l capacity and 5.6 m²/m ³ cooling area was designed and tested for MgSO₄ crystallization. A heat flux of 1720-5750 W/m² was achieved at a temperature difference between coolant and crystallizer bulk solution of 3-6.5 K and a residence time of 1-3 h. Crystallization and gravitational separation of ice and salt are discussed.
