在工业结晶中，经常采用播种技术进行启动操作。从间歇结晶到连续结晶，其应用各不相同。众所周知，启动操作所需的时间根据种子晶体规格的经验而变化。在这项研究中，为了缩短启动操作所需的时间，对连续混合悬浮混合产品脱除(MSMPR)结晶器的晶种规格进行了研究。采用常规的MSMPR结晶器模型，模拟了启动过程中晶粒度分布的变化。结果表明，在启动过程中加入晶种对CSD的变化有显著影响。通过对不同规格的种子晶体进行实验和模拟，提出了一种设计合适的种子晶体的策略。
In the industrial crystallization, seeding technology is often used for start-up operation. The applications vary from batch to continuous crystallization. It is known that the required time for the start-up operation changes by seed crystal specifications experientially. In this study, designing seed crystal specifications for a continuous mixed-suspension mixed-product removal (MSMPR) crystallizer was investigated to shorten the required time for start-up operations. The changes of crystal size distribution (CSD) during start-up operation were simulated by using conventional MSMPR crystallizer model. It was shown that the addition of seed crystals in start-up operations had a remarkable influence on the changes in CSD. As a result of experiments and simulation with various specifications of seed crystals, a strategy to design adequate seed crystals was proposed.
