Oxygen Scavenger

The Oxygen Scavenger is used for removing oxygen from boiler feed water straight away. The various products which we manufactured are Boiler oxygen scavenger, catalyzed sodium sulphite, hydrazine hydrate, powdered antiscalant and oxygen scavenger etc. 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. These chemicals also proclaims to be a metal passivator and rust convertor and proves to be a single treatment for total corrosion control in any industrial plants.

Hydrazine Hydrate with Catalyst

CHEMTEX'S Hydrazine Hydrate With Catalyst is a very effective oxygen scavanger based on a volatile liquid formulation of hydrazine and catalyst. It is used to remove the even the last traces of dissolved oxygen from the boiler feed water by the following equation:-

O2+ N2H4 2H2O + N2 Oxygen + 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.

Please refer to your CSL service engineer for exact product dosage and dosing practice.

DEHA

CHEMTEX'S Deha is a volatile catalyzed oxygen scavenger cum condensate line treatment chemical. It is based on DEHA catalyzed with hydroquinones.

CHEMTEX'S Deha reacts with oxygen to form acetates, nitrogen and water. It passivates the metal surfaces in the boiler, and then passes out of the boiler with the steam, and act as a metal passivating agent in the return line system.

Key Features and Benefits
  • Completely organic compound
  • Volatile - Does not add TDS to blow down water
  • Metal passivator and rust converter
  • Effective condensate line treatment and pH booster
  • Non-toxic and more safe than hydrazine and carbohydrazide based chemicals
  • Compatible with other treatment chemicals
  • Returns to the feed line with the condensate return so passivates total system
  • High rate of reaction with oxygen compared with other oxygen scavengers
  • It offers a vapor-liquid distribution ratio of 1.3 and thus distributes all along the condensate circuit, ensuring a total control of corrosion
  • Single treatment for total corrosion control in boiler

Application and Dosage
CHEMTEX'S Deha is fed neat (undiluted) continuously to the boiler feed water depending upon the dissolved oxygen content, temperature and pressure of boiler. Theoretically the dosage is 1.3 parts active ingredient for every part of oxygen, but in application, a dosage of 3ppm active for every ppm of O2 is recommended.

Handling measures and precautions
Proper human safety products such as Splash goggles, lab coat, vapor respirator, gloves and boots should be worn while handling and applying chemicals. Splashes on skin should be washed off with water immediately. In case of splashing into the eyes, flush it with fresh water and obtain medical attention. Should not be injected.
