ABSTRACT:
A process for producing sodium carbonate and other sodium-based chemicals from an aqueous solution containing sodium bicarbonate by contacting an aqueous solution of a bicarbonate-containing composition with a gas that is predominately other than carbon dioxide in an amount and for a time adequate to cause a sufficient amount of carbon dioxide to leave the aqueous solution to reduce the amount of bicarbonate ion in the solution by converting the bicarbonate to carbonate as carbon dioxide leaves the solution and thereafter converting the remaining solution to other sodium salts.
