Abstract
PURPOSE: To economically separate a specific component from two or more of mixture components in high pressure fractional crystallizer, a pressure piston and heater equipped crystallizer is incorporated into a special high pressure container.
CONSTITUTION: The device 1 comprises a shell 4 with internal heat insulator 19, heater 11, a bottom lid portion 5 attached with filter made of internal wire net 7b, heat insulator 17, and a pressure piston ram 6 attached with filter of the same composition. The sequential device operation comprises; closing valve 14a, b; admitting compressed solid-liquid mixture into the device 1 through pump 2 and valves 13a, b; closing valves 13a, b; opening valves 14a, b; and pressure exertion by piston ram 6. The process results in increased crystal component, which is separated by removing mother liquor through filter 7a, 7b by adjusting pressure control 3. Insulator and heater are provided to prevent rapid filter cooling that will casue liquid choking by crystallization. The process eliminates conventional cooling means while effecting accelerated crystal formation and inexpensive separation of a specific component.
