ABSTRACT:
An anhydrous sodium carbonate crystal is produced by crystallizing a sodium carbonate hydrate crystal from an aqueous solution of sodium carbonate in a sodium carbonate hydrate crystallizing zone and transforming said sodium carbonate hydrate to an anhydrous sodium carbonate crystal in the presence of a crystal habit modifier in an anhydrous sodium carbonate crystallizing zone and recycling a separated mother liquor into said sodium carbonate hydrate crystallizing zone.
