Product code RXSOL-42-1524-050
Extremely suitable oxygen scavenger for low and medium pressure boilers.
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.
CHEMZOL 9200 is a easy to handle liquid solution that can be used as both a powerful oxygen scavenger for low and medium pressure steam boilers and also a neutraliser for removing chlorine and other biocides to protect sensitive systems such as RO plants or prior to discharge to the environment. CHEMZOL 9200 Oxygen Scavenger is intended for applications such as the food industry where formulations including heavy metal catalysts cannot be used.
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 Oxygen Scavenger Boiler Oxy Control as a chemical deoxygenator is economical within certain limitations imposed by the dissolved oxygen content. Oxygen Scavenger Boiler Oxy Control 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 Oxygen Scavenger Boiler Oxy Control to react with the residual oxygen.
To prevent corrosion and pitting it is desirable to feed the Oxygen Scavenger Boiler Oxy Control. Oxygen scavengers capture the dissolved oxygen in a harmless chemical reaction that renders the oxygen unavailable for corrosive reactions.
Features of CHEMZOL 9200 Oxygen Scavenger
- Reacts with oxygen to produce compounds that do not harm boiler integrity. One of these compounds further improves protection against caustic embrittlement.
- Suitable for low and medium pressure boilers
- Catalysed product to ensure efficient protection from corrosion
Dosage
As Boiler Water Oxygen Scavenger
Rapid reaction with oxygen ensures efficient protection of feedlines and boilers from corrosion. RXSOL-42-1524-050 is intended for those applications such as the food industry where heavy metal catalysts cannot be used. RXSOL-42-1524-050 reacts with oxygen to form bi-products which have no adverse effect on boiler integrity. One of these bi-products enhances protection against caustic embrittlement.
CHEMZOL 9200 Oxygen Scavenger should be dosed at the rate of 18ml/m3 for every ppm of dissolved oxygen. A reserve of approximately 50ppm of sulphite should be maintained in the boiler water.
As Biocide Neutralizer
CHEMZOL 9200 Oxygen Scavenger is an effective neutraliser of halogens, particularly chlorine, and a wide range of other biocides. It can be used to neutralise excess chlorine following disinfection of water systems, including cooling water systems and the feed to RO systems. CHEMZOL 9200 Oxygen Scavenger can also be used to prepare waste streams for disposal to treatment services, including public utility services, by conditioning residual biocide including, but not limited to, C/MIT, DBNPA and THPS.
CHEMZOL 9200 Oxygen Scavenger is dosed at the rate of 7 – 10 ml/m3 per mg/l of free chlorine
Theoretically, 7.88 pounds of RXSOL-42-1524-050 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-42-1524-050 are required for each pound of oxygen removed (or 10 ppm RXSOL-42-1524-050 per 1 ppm dissolved oxygen.)
