Abstract:
A process for producing crystalline sodium bicarbonate, comprising: providing an aqueous sodium-bicarbonate containing liquor originating from a reactive crystallization step in which first sodium bicarbonate crystals are produced and recovered; feeding at least a portion of said aqueous sodium-bicarbonate containing liquor to a cooling crystallization unit to form second sodium bicarbonate crystals and produce a crystals slurry comprising the second sodium bicarbonate crystals; and withdrawing a portion of the crystals slurry from the cooling crystallization unit for the withdrawn second sodium bicarbonate crystals to be further processed. A portion of the second sodium bicarbonate crystals withdrawn from the cooling crystallization unit may be fed to a sodium bicarbonate reactive crystallization unit, to a caustic unit, or may be separated and dried. The reactive crystallization, separation and/or drying units where the second sodium bicarbonate crystals are further processed may be the same units where the first sodium bicarbonate crystals are processed.

Claim (Index 10):
The process according to  claim 9 , wherein the at least one crystal modifier additive comprises calcium (Ca), and wherein calcium is added to reach an amount from 30 mg to 200 mg Ca per kg of the first sodium bicarbonate crystals produced.
