Feed Water Treatment to Avoid Corrosion Engineering ToolBox

Sodium Sulfite decomposes on heating and is prepared from sulfur dioxide and sodium carbonate or caustic soda. Sodium Sulfite is an effective scavenger for use in systems operating below 1000 psi. For pressures above 1000 psi breakdowns may form corrosive Hydrogen Sulfide and/or Sulfur Dioxide.
