Oxygen Scavenger
Powerful concentrated corrosion inhibitor acts as oxygen scavengers used to effectively remove dissolved OXYGEN
Oxygen Scavenger – Sodium Sulphite
Product Description:
Oxygen Scavenger – Sodium Sulphite is a highly effective oxygen scavenging chemical formulated to remove dissolved oxygen from boiler feed water, injection water, and industrial water systems. It rapidly reacts with dissolved oxygen, preventing corrosion in pipelines, boilers, heat exchangers, storage tanks, and water injection systems.
The product is widely used in the oil & gas, power generation, petrochemical, refinery, and water treatment industries to maintain low dissolved oxygen levels and protect critical equipment from oxygen-induced corrosion.

BENEFITS -
RAPID REACTION :
The catalyst RXSOL-81-6119-220 speeds up the removal of dissolved oxygen. Oxygen can be removed completely even from cold water due to catalytic action. Normal reaction time is as low as 15 to 20 seconds as against 10 to 30 minutes for uncatalysed sulphite.
EASY TO HANDLE :
RXSOL-81-6119-220 is a free flowing powder. It is soluble in water even at lower feed water temperature.It is non-toxic and non-corrosive and, therefore, can be handled easily.
pH CONTROL :
RXSOL-81-6119-220 is formulated to get proper pH control for optimum availability of catalyst for rapid oxygen removal.
COST EFFECTIVE :
The catalytic action reduces the excessive requirement of sulphite in feed water for the rapid removal of oxygen. Thus the quantity required is lower, making RXSOL-81-6119-220 treatment cost effective.
APPLICATION AND DOSAGE :
RXSOL-81-6119-220 solution should be dosed continuously. Dissolve the required quantity of RXSOL-81-6119-220 gently in boiler feed water in a separate tank. Dose this solution continuously in the boiler feed water line after the deaerator.
Above 8 ppm of sodium sulphite is required for the removal of 1 ppm of dissolved oxygen from boiler
feed water. About 10% to 20% of excess sulphite should be dosed to provide oxygen consuming reserve.
The table below gives the approximate dosage.

Carbohydrazide is used as an oxygen scavenger for high pressure boilers in power plants and other industries to reduce corrosion of metal pipes and fittings.
What is CarboHydrazide ?
Carbohydrazide the hydrazide of carbonic acid.
Why Hydrazine is replace by Carbohydrazide ?
Carbohydrazide (CH6N4O) - RXSOL-42-2541-025 is an oxygen scavenger often added to boiler systems to control corrosion. It reacts with oxygen at low temperatures and pressures. It also passivates metal surfaces preventing further corrosion. The reaction products are volatile, so they do not contribute to dissolved solids in the system. Carbohydrazide is widely used to replace hydrazine as an oxygen scavenger because it is less toxic.
Recommended dose of Carbohydrazide :
|
Low Pressure Boiler ( 0 to 40 bar ) |
0.10 to 0.2 ppm level |
|
Medium Pressure Boiler ( 41 to 60 bar ) |
0.1 to 0.15 ppm level |
|
High Pressure Boiler ( more then 60 bar) |
0.05 to 0.10 ppm level |
Carbohydrazide also Widely used in medicine, herbicides, plant growth regulators, dyes and other industries. RXSOL is Top chemicals manufacturer and exporter of Various Water Treatment Chemicals and Agriculture Chemicals, Marine and Oil Field Chemicals, Tank Cleaner.
Carbohydrazide supplier in Mumbai, Kolkata, Gandhidham, Chennai, Visakhapatnam, Fujairah, Dubai, Abudhabi Sharjah Muscat Oman, Canada. Carbohydrazide plays very important role for corrosion protection in boilers water treatment.
