Procedure
In a brief overview, sodium sulfite may be manufactured commercially by preparing a sodium sulfite liquor by the reaction of sodium carbonate with sulfur dioxide in a reactor. The reaction produces sodium sulfite with carbon dioxide (CO2) as a by-product. The reactor liquor is then fed to a crystallization system, which includes a crystallizer and a crystallizer heater in a heater circulation loop connected to the crystallizer. The liquor is moved by the help of a circulating pump in the heater circulation.
