RIGS Oil Field
Oxygen Scavenger OxyGuard S
Product code RXSOL-34-6119-250
Powerful concentrated corrosion inhibitor acts as oxygen scavengers used to effectively remove dissolved OXYGEN
Description
This is most common oxygen treatment as a scavengers used to effectively remove dissolved OXYGEN from your feedwater. By the presence of dissolved oxygen in system, corrosion and pitting caused on metal surface. Removes dissolved oxygen, By acting as an oxygen scavenger.
A fast-acting, catalyzed sodium sulphite (Na₂SO₃) oxygen scavenger for low- and medium-pressure boiler systems. The product reacts stoichiometrically with dissolved oxygen to prevent corrosion in boilers, feed lines, and condensate systems by converting oxygen to inert sulfate.
Application
Application
Key Areas of Application of Oxygen Scavenger OxyGuard-S
- Oxygen removal in low/medium-pressure boilers (typically up to ~65 bar; usage above this pressure is uncommon due to potential sulfate/solids carryover).
- Hot standby protection to prevent pitting during idle periods i.e. Oilfield Application.
- Feedwater & deaerator outlets where residual O₂ must be suppressed rapidly.
Precautions
Precautions
Control test methods:
- Residual sulfite by iodometric titration (express as mg/L Na₂SO₃).
- Dissolved oxygen by luminescent/optical or membrane DO analyzer at DA outlet.
- Start with calculated stoichiometric dose + safety factor based on measured DO.
- Adjust pump to maintain target sulfite residual in the boiler drum.
- Increase dose for intermittent operation, cold feeds, or high leakage air into DA.
- For wet lay-up, raise sulfite residual to upper range and circulate periodically.
- Compatible with phosphates, chelants (as per program limits), and dispersant polymers used for scale/sludge control.
- Avoid co-feeding with oxidizing biocides (e.g., chlorine) as they will consume sulfite.
- Downstream of RO systems, sodium bisulfite is typically preferred for dechlorination; this product is not intended as an RO dechlorinator.
