ABSTRACT:
Sodium carbonate is formed by reaction between particulate sodium aluminate in solid form, and carbon dioxide and water vapor in gaseous form. The sodium carbonate is readily separated from by-product hydrated alumina for recovery in pure form, or the dry product of the reaction may be employed directly where a dry sodium carbonate feed is desired, with the hydrated alumina being filtered off prior to further processing.
