Procedure

The mother liquor, preferably, is treated and prepared before being passed to the decahydrate crystallizer 17. Water is added through line 56 to the mother liquor in line 54 to dilute it so that the concentration of sodium bicarbonate entering the crystallizer 17 via line 58 is reduced. At preferred operating conditions, diluted mother liquor has a concentration of sodium bicarbonate of about 3.5% and a concentration of sodium carbonate of about 15.3%. The dilution insures that no sodium bicarbonate will precipitate out when the mother liquor is cooled to form sodium carbonate decahydrate crystals.
