Chemical scavengers are used to remove dissolved oxygen from water-flow streams of less than 10,000 B/D. There are a number of compounds commercially available to remove dissolved oxygen, and all can be considered as a source of sulfur dioxide or sulfite. These include: sodium sulfite (Na 2 SO 3) sulfur dioxide (SO 2)
