Sodium Sulfites - an overview | ScienceDirect Topics

The Wellman-Lord process uses sodium sulfite to absorb SO 2, which is then regenerated to release a concentrated stream of SO 2. Most of the sodium sulfite is converted to sodium bisulfite by reaction with SO 2, as in the dual alkali process. Some of the sodium sulfite is oxidized to sodium sulfate.
