| titleOfInvention | Purification method for an alkali metal chloride and method for producing an alkali metal hydroxide |
| abstract | A method for producing sodium carbonate, which comprises: (a) obtaining a mixture comprising sodium chloride and other water-soluble inorganic salt by neutralization treatment of a gas containing hydrogen chloride with sodium hydroxide, sodium carbonate, sodium hydrogencarbonate or sodium sesquicarbonate, wherein said gas containing hydrogen chloride is a gas formed by refuse incineration or combustion in a boiler, (b) purifying said sodium chloride, wherein water or an aqueous solution of said sodium chloride is added to the mixture obtained in step (a) in such an amount that is sufficient to dissolve at least one type of said other water-soluble inorganic salt substantially in its entire amount and that is not sufficient to dissolve said sodium chloride substantially in its entire amount, thereby to dissolve said other water soluble inorganic salt substantially in its entire amount, (c) subjecting the slurry obtained in step (b) to a solid-liquid separation to recover the sodium chloride as solid component, and (d) producing sodium carbonate of an aqueous solution of the sodium chloride obtained in step (c) by an ammonia soda process. |
