Bicarbonate conversion in a carbonate monohydrate process |
摘要 |
A method for converting sodium bicarbonate in a sodium carbonate monohydrate crystallization process to maintain a mother liquor composition in a sodium carbonate monohydrate crystallizer below the invariant point for the crystallizer for reducing or eliminating the co-crystallization of sodium sesquicarbonate crystals in the process. The mother liquor composition may be maintained below the invariant point by stripping carbon dioxide from a feed solution or from mother liquor recycled to the crystallizer.
