Mixing Effects in Continuous Crystallizationas been found concerning production size equipment. Unfortunately, in large systems good backmixing is seldom if ever achieved. In fact, it is often purposely avoided, and as a result improvements in size distribution are achieved. Therefore, the question that arises is can any significant analysis
