Industrielle Kristallisation - Moderne gro?technische Anlagen und Fallstudien

Industrial crystallization – Modern industrial plants and case studies. In the field of mass crystallization a number of advanced plant designs have been implemented in the past decade, and are exemplified in the crystallization of adipic acid and common salt, and in evaporation of aluminate liquor which is susceptible to encrustation. Assessment criteria are, inter alia, product qualities such as the purity achieved and the crystal size distribution, and operation parameters such as the duration of process flow and control behaviour. The significant increase in quality is largely attributable to the crystallizers, which have been optimized above all with regard to the crystal-size distribution and the duration of product flow.
