Ammonium Bisulfite Oxygen Scavenger
Product Description
Ammonium Bisulfite Oxygen Scavenger is a high-performance, water-soluble oxygen scavenger formulated for the rapid removal of dissolved oxygen from industrial and oilfield water systems. The product is based on ammonium bisulfite (NH₄HSO₃), which reacts with dissolved oxygen and converts it into stable, water-soluble sulfate compounds.
Dissolved oxygen is a major contributor to pitting and general corrosion in pipelines, injection systems, process equipment and water-handling facilities. By reducing dissolved oxygen concentration, Ammonium Bisulfite Oxygen Scavenger helps minimize oxygen-induced corrosion and improves the reliability and service life of associated equipment.
The product is particularly suitable for oilfield injection water, produced-water treatment, seawater injection systems and other industrial water circuits where effective dissolved-oxygen control is required. Its completely water-soluble liquid form allows convenient continuous dosing and rapid distribution throughout the treated system.
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.
Application
Oxygen Treatment scavenger is a class of chemicals added to react and remove oxygen in water to protect against oxygen induced corrosion. The use of Ammonium Bisulfite as a chemical deoxygenator is economical within certain limitations imposed by the dissolved oxygen content. Ammonium Bisulfite is relied on as the sole means of oxygen removal. Generally, costs are balanced by removal of as much of the oxygen as feasible by mechanical means, e.g. deaerator and by using Ammonium Bisulfite to react with the residual oxygen.
To prevent corrosion and pitting it is desirable to feed the Ammonium Bisulfite.
Dosage
Theoretically, 7.88 pounds of RXSOL-81-6119-220 are required to remove one pound of oxygen. The efficiency of the oxygen removal is estimated at 75 per cent to allow for oxidation in contact with air, blowdown losses, etc. Therefore it is estimated that 10 pounds of RXSOL-81-6119-220 are required for each pound of oxygen removed (or 10 ppm RXSOL-40-5023-210 per 1 ppm dissolved oxygen.)
Uses
Ammonium Bisulfite Oxygen Scavenger is suitable for use in:
- Oilfield water injection systems
- Seawater injection systems
- Produced-water treatment systems
- Waterflood operations
- Oil and gas production facilities
- Injection pipelines and flowlines
- Deaerated water systems
- Closed-loop industrial water systems
- Process-water systems
- Hydrotest and preservation water, where chemically appropriate
- Storage and transfer systems requiring dissolved-oxygen control
- Corrosion-control programs where oxygen removal is an essential part of the treatment strategy
