摘要：The present invention pertains to a process for producing sodium chloridecomprising the steps of: (i) preparing a brine having a sodium chloride concentration
which is higher than the sodium chloride concentration of the eutectic point but lowerthan the sodium chloride concentration of a saturated brine by dissolving a sodiumchloride source in water; (ii) cooling the resulting brine by indirect cooling in a self-cleaning fluidized bed heat exchanger/crystallizer to a temperature lower than 00 C buthigher than the eutectic temperature of the resulting brine, thereby forming a slurrycomprising sodium chloride dihydrate and a mother liquor; (iii) feeding the sodiumchloride dihydrate to a recrystallizer to form sodium chloride and a mother liquor, and(iv) recycling at least part of the mother liquor obtained in step (ii) and/or step (iii) to step(i).
