Hydrazine‑Free Oxygen Scavenger for Marine Boilers
The hydrazine replacement oxygen scavenger marine boiler is engineered for ship‑board steam systems where safety, reliability, and compliance are non‑negotiable. It eliminates dissolved oxygen without the hazardous profile of traditional hydrazine, protecting boiler tubes, condensate lines and heat‑exchange surfaces from corrosion while meeting IMO‑approved environmental standards. Designed for both new builds and retro‑fits, this chemically stable formulation integrates seamlessly with existing feed‑water treatment loops.
Real‑World Application Scenarios
Our oxygen scavenger is trusted across a range of marine vessels and offshore platforms:
- Container ships and bulk carriers operating on high‑temperature, high‑pressure boiler cycles.
- Naval warships where crew safety mandates non‑toxic water‑treatment chemicals.
- Floating production storage and offloading (FPSO) units with continuous steam generation.
- Cruise liners that require strict compliance with passenger‑health regulations.
Technical Overview & Key Benefits
Replacing hydrazine eliminates a Class 3 hazardous material from your inventory, simplifying storage, handling, and documentation. The formulation offers:
- Rapid oxygen removal: achieves < 5 ppb residual O₂ within 30 minutes at typical boiler feed rates.
- Temperature stability: effective from 0 °C to 120 °C, covering all marine boiler operating windows.
- Low sludge formation: reduces deposit buildup, extending cleaning intervals and boosting heat‑transfer efficiency.
- Environmental compliance: meets IMO 2020 and MARPOL Annex V limits for toxic discharge.

Frequently Asked Questions
What is the minimum order quantity (MOQ) for the scavenger?
Standard MOQ is 500 kg per grade, but we accommodate smaller pilot batches (as low as 100 kg) for evaluation projects. Custom packaging and blending can be arranged to meet ship‑store constraints.
Can the formulation be tailored for specific boiler pressures?
Yes. Our R&D team can adjust the sulfite concentration and stabilizer package to optimise performance for pressures up to 30 bar. Such modifications are reflected in the technical data sheet provided with each batch.
What is the typical lead time from order to delivery?
For stocked grades the lead time is 15‑25 working days. Custom blends require 30‑45 days, depending on formulation complexity and packaging specifications.
Does the hydrazine replacement oxygen scavenger marine boiler carry a warranty?
All shipments are backed by a 12‑month warranty covering material defects and compliance deviations. Technical support is available 24 hours a day, 7 days a week, throughout the warranty period.
