Manufacturing Process

This report comprises a thorough value chain evaluation for Sodium Bisulfite manufacturing and consists of an in-depth production cost analysis revolving around industrial Sodium Bisulfite manufacturing.

• Production via Chemical Synthesis (Sulfonation and Neutralisation): The feedstock for this method includes sulfur dioxide (SO2) and sodium carbonate (Na2CO3). The production of sodium bisulfite begins with the reaction of sulfur dioxide gas with a sodium carbonate solution. When sulfur dioxide is introduced into the sodium carbonate solution, a chemical reaction occurs, which leads to the formation of sodium bisulfite. The process happens as the sulfur dioxide dissolves in the solution and combines with sodium carbonate. Once the reaction is complete, the sodium bisulfite is carefully separated from the mixture. The final step involves purifying the sodium bisulfite to remove any remaining impurities, ensuring that the end product is pure and suitable for use. This purified sodium bisulfite is then collected as the finished product.
