Förfarande och anordning för kristallisering av ett oorganikst ämne och sålunda erhållna natriumkloridkristaller

摘要

Process and plant for the crystallisation of an inorganic substance in which a supersaturated solution of the substance is forced to circulate through a fluidised-bed (14) reactor (2) after having passed through a distributor (12) maintained at a temperature at which the concentration of the supersaturated solution is lower than or equal to the concentration corresponding to saturation. The invention applies to the crystallisation of sodium chloride.
