Abstract:
1. A method of forming nuclei and subsequently crystals in a feed solution, comprising the steps of: a) conveying said feed solution into a solid hollow fiber crystallizer (SHFC) system, said solid hollow fiber crystallizer system including a plurality of non-porous hollow fibers mounted within a shell and said feed solution being conveyed to either a lumen side or a shell side of said plurality of non-porous hollow fibers; b) conveying a cooling solution into said solid hollow fiber crystallizer, said cooling solution being conveyed to an opposite side of said plurality of non-porous hollow fibers as compared to said feed solution; c) cooling said feed solution below its saturation temperature to form nuclei and crystals; and d) conveying said cooled feed solution into a mixing device.
