Title: Method and installation for continuous crystallization of liquids by freezing

Abstract: An installation is described for continuous crystallization of liquids by freezing. The installation performs liquid preliminary cooling under predetermined temperature; adding gas into cooled liquid and their intermixing; delivering mixed liquid and gas through the refrigerated evaporator; winding round mixed liquid and gas into the refrigerated evaporator; a pumpless refrigeration circuit, including compressor, water condenser, cooling tower, indirect refrigerated evaporator, expansion valve, low pressure receiver and required refrigeration accessories, for the realization of cooling volumetric crystallization of liquid flowing through the refrigerated evaporator. These processes cause the formation of a bubble slurry with crystal nuclei, gas bubbles and concentrated, unfrozen liquid; preparation means are described for transportation and further storage or use of bubble slurry; immovable means are designed for feasible separation of pure fine crystals and mother concentrated liquid.
