Procedure

In a brief overview, a source of sodium carbonate (e.g., via line 111) with a source of sulfur dioxide (e.g., via line 112) are fed to the reactor 110 under conditions suitable to produce sodium sulfite with carbon dioxide as a by-product and generate a sodium sulfite liquor which exits reactor 10 via line 114. The reactor 110 is typically operated at a temperature from 120° F. to 140° F. (from 48.9 to 60° C.), or at about 160° F. (about 71° C.).
