Sodium Sulfite Storage — Na2SO3 Boiler O2 Scavenger Tank

Storing Sodium Sulfite? Start Here

If you're dealing with sodium sulfite, you're likely using it as a boiler oxygen scavenger or in processes like pulp milling or wastewater treatment. It's a white crystalline solid or a solution, and it's crucial to store it properly to maintain its effectiveness. Sodium sulfite solutions can oxidize when exposed to air, turning into sulfate and losing their reducing power. So, minimizing air exposure during storage is key to keeping it active.

Can you store it in a poly tank?

Yes, you can store sodium sulfite in a polyethylene tank. It's compatible with HDPE and XLPE, making them great choices for day tanks and bulk storage. Just ensure the tank is sealed to prevent air exposure.

Watch out for air exposure

The main issue with sodium sulfite storage is its tendency to oxidize when it comes into contact with air. This means you'll need to keep your storage tanks well-sealed and consider using a nitrogen blanket for larger tanks to keep the air out.

The safety that actually matters

• Keep tanks sealed to prevent oxidation.
• Use appropriate gaskets—check the manufacturer's chart to match them correctly.
• Handle with care to avoid skin and eye irritation.

Common questions

Can sodium sulfite be stored outside?

Yes, but ensure the tank is sealed and protected from the elements to prevent air exposure.

What should I do if sodium sulfite oxidizes?

Once oxidized, it loses its effectiveness as a reducing agent. Prevent this by maintaining airtight storage.

Is a special permit needed for storing sodium sulfite?

Generally, no special permit is needed, but always check local regulations for specific requirements.
