Title:
CRYSTALLIZATION METHOD AND CRYSTALLIZATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/053780
Kind Code:
A1
Abstract:
Provided is a crystallization method in which a circulation passage (12) is formed between a main reaction unit (11) and a concentration reaction vessel (13) to perform reactive crystallization, in which the circulation passage (12) has an inflow passage (12a) for the inflow from the main reaction unit (11) to the concentration reaction vessel (13) and an outflow passage (12b) for the outflow from the concentration reaction vessel (13) to the main reaction unit (11), an agitation zone (14) in which the inflow passage (12a) and the outflow passage (12b) are connected to each other is provided below the concentration reaction vessel (13), a clarification zone (18) in which a supernatant is produced is provided above the concentration reaction vessel (13), and a concentration zone (17) in which particles are precipitated is provided between the agitation zone (14) and the clarification zone (18).
