A new stacked, continuous, scalable, high performance crystallizer
Crystallization, while most often performed in batch, can provide process control advantages and ease of scalability when performed continuously. However, current continuous equipment has not fulfilled the technological needs of the field. Here, we present a novel design for a scalable continuous crystallizer. The devices has 11 vertically stacked tanks, provides tight control of processing parameters, and is capable of moving slurry without the need for transfer lines eliminating the major source of fouling plaguing traditional multistage techniques. This device architecture provides a basis for increased crystal product quality by providing excellent mixing, supersaturation, and temperature control. We give an overview of our device and existing techniques, present single tank mixing study scalability data, RTD data in multistage systems, and conclude by discussing ongoing efforts.
