MVR-OSLO Continuous Crystallizer
MVR-OSLO Continuous Crystallizer – High Efficiency System
An MVR-OSLO continuous crystallizer combines the MVR system with the OSLO crystallization system. The OSLO crystallizer was proposed by a Norwegian named Jeremiassen in the 1930s, and it is often referred to as the Krystal crystallizer or size-grading crystallizer.
After entering the system, the liquid flows into the evaporator by means of a circulating pump and is heated to evaporate. The generated vapor then enters the evaporation chamber, where the concentrate separated from the secondary vapor is delivered through the central downflow line to the bottom, where crystals grow. The liquid then passes upward through the crystal fluid bed to avoid supersaturation. In this way, the crystals in the bed gradually grow and are discharged from the outlet once they reach the required size.
The secondary vapor increases in temperature and pressure through the MVR system and is subsequently recovered for reuse. This design makes full use of the latent heat during evaporation and therefore achieves the goal of energy savings.
