Abstract

PURPOSE:To enhance compression and separation efficiency of mother liquor and to achieve enhancement of purity of a specified component and enhancement of recovery thereof at one stroke by making crystal having the specified component which is produced in a crystallizing process to as large-sized crystal as possible. CONSTITUTION:The coexistent state of both a small amount of seed crystal consisting of a specified component and mother liquor contg. this specified component is formed and this mixture is held in a region of metastable pressure of the specified component in this state and thereby large crystal which consists of the specified component and has superior quality is obtained and thereafter separation of mother liquor is performed by filtration, compression, etc. As a result, compression and separation efficiency of mother liquor is enhanced and enhancement of purity of the specified component and enhancement of recovery thereof can be achieved at one stroke.
