【 摘 要 】

References(5)Cited-By(1)Industry has recently been keenly interested in obtaining highly pure crystal. A KCP (Kureha Crystal Purifer) is one type of equipments for obtaining that kind of crystal. This KCP purifies only crude feed crystal; therefore, it requires a crystallizer. Recently, we have found that the crystal from a CDC (Cooling Disc Crystallizer, manufactured by GMF-Gouda, the Netherlands) is superior to the crystal from a drum flaker and can be best suited for producing the feed crystal for the KCP. Thus, the combination of the KCP and CDC can be one of the most effective types of continuous fractional column crystallization.
