Oxygen Scavenger
The Oxygen Scavenger is used for removing oxygen from boiler feed water straight away. This catalyzed scavenger converts itself to sodium bisulfate and remove oxygen instantly from boiler feed water. It is also responsible for buffering pH and reducing alkalinity of the feed water. Having precise pH value, this chemical is acknowledged for its attributes like saving power energy, minimize oxidation corrosion, removes oxygen and precise pH value. This formulation range is idyllically utilized in food & beverage, dairies, pharmaceutical, poultry and sugar industries.

Hydrazine Hydrate with Catalyst
O2+ N2H4 2H2O + N2Oxygen + Hydrazine Water + Nitrogen Gas
The catalyst in the product helps to increase the rate of the above reaction and ensures complete removal of dissolved oxygen in boiler feed water in lesser time.
Chemtex’s Hydrazine Hydrate With Catalyst also prevents corrosion by forming a protective passive film on metal and by boosting the pH in condensate line.
Key Features and Benefits
- Catalyzed Oxygen Scavenger for instant oxygen removal
- Does not add to the TDS of boiler water, since the product is volatile
- Minimizes oxidation corrosion (corrosion due to presence of oxygen)
- Catalyst in the product reduces the requirement of hydrazine for oxygen removal
- Prevents corrosion by forming a passive protective film over the metal surface
- Increases the condensate pH and minimizes corrosion of steam lines
Application and Dosage
Chemtex’s Hydrazine Hydrate With Catalyst is dosed at the rate of 5ppm for every ppm of dissolved oxygen from boiler feed water. It is recommended to maintain an excess dosage of 1.1 to 1.2 times the desired dosage as reserve for compensating the variation in oxygen content.
