Procedure

In U.S. Pat. No. 3,628,919 to Beauchamp, there is described a process for crystallizing sodium carbonate (possibly monohydrated) starting from aqueous solutions containing organic materials. It aims more particularly at furnishing a process which avoids the unfavorable action of these organic materials on the sodium carbonate crystals. According to the Beauchamp process, sodium carbonate is crystallized onto seed crystals obtained under good crystallization conditions. The choice of the source of seed crystals is not however critical. Further, the Beauchamp patent is not concerned with the use of carbon dioxide (CO2) to carbonate an aqueous solution of sodium hydroxide and then evaporated to produce seed crystals of sodium carbonate monohydrate free of sodium hydroxide.
