Procedure

The first feed liquor may be treated as it is passed via line 58 to the decahydrate crystallizer 17. Cool water may be added through line 54 to the decahydrate crystallizer 17, or elsewhere upstream, to dilute the first feed liquor so that the concentration of sodium bicarbonate is reduced. The first feed liquor should be diluted so that the concentration of sodium carbonate is about 3.5% or less. The dilution insures that no sodium bicarbonate will precipitate out when the first feed liquor is cooled to form sodium carbonate decahydrate crystals.
