摘要

Process for the production of crystals of sodium chloride from brine of sodium chloride contaminated with potassium chloride and sulphate ions "process for the production of crystals of CloreTo sodium from a sodium chloride brine contaminated with potassium chloride and sulphate ions.It adds a calcium compound (32) to the brine (48) to crystallize glauberita (35) that is pushed to the side.The resulting aqueous solution is subjected to evaporation (36) to crystallize sodium chloride (40).It collects and submits the water mother (41) of the crystallization of sodium chloride to a cooling (42) to crystallize the glaserita (45).
