Abstract
The present invention relates to a method and installation for the crystallisation of a liquid from a solution, a suspension or a mixture of liquids using a crystalliser 2 which, for example, is provided on its wall with a heat exchanger 4 and comprises a single chamber for both nucleation and growth. Depleted mother liquor is withdrawn from the crysiallisation vessel via a filter 10 located in the crystalliser, so that the crystal content in the vessel can be accurately adjusted for the purpose of optimum separation of the crystals, preferably using a packed-bed wash column. The crystalliser preferably contains a stirrer with the filter on the stirrer 5 shaft. The filter rotates past a scraper 12, which is arranged in a fixed position, as a result of which the filter cake can be reintroduced into the suspension without damage to the crystals.
