<p>An installation for continuous crystallization of liquids by freezing to form a bubble slurry with crystal nuclei, gas bubbles and concentrated unfrozen liquid. The installation includes a pumpless refrigeration circuit with a compressor, a water condenser, a cooling tower, an indirect refrigerated evaporator, an expansion valve, a low pressure receiver and refrigeration accessories for volumetric crystallization of liquid flowing through the refrigerated evaporator. The installation performs preliminary liquid cooling at a predetermined temperature, adding gas into the cooled liquid and their intermixing, delivering mixed liquid and gas through the refrigerated evaporator and winding round the mixed liquid and gas into the refrigerated evaporator.</p> |
