CHEMZOL 9200
Product code RXSOL-42-1524-050
Extremely suitable oxygen scavenger for low and medium pressure boilers.
Description
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
Precautions
The most common oxygen scavengers in oilfield production are sodium bisulfite (SBS) and ammonium bisulfite (ABS). Ammonium bisulfite is more water soluble than sodium bisulfite and typically react with oxygen faster. However, ammonium in the ammonium bisulfite can promote bacteria growth.
Being a salt of a weak acid and a strong base, sodium bisulfite forms a significantly basic aqueous solution whereas ammonium bisulfite is only slightly basic at around pH 8. As a rule of thumb, 60ppm of 65wt% ammonium bisulfite is required to reduce the oxygen concentration in water from 9ppm to 50ppb.
The reaction of bisulfite with oxygen is typically faster at higher temperatures and can be facilitated by transition metal ion catalysts, e.g. Cobalt.
The most common applications of oxygen scavenger in oil and gas production are for seawater injection facilities, hydro-testing, and acid stimulation
It is used to arrest oxygen in sea water
It removes Entrapped Oxygen and thus reduces Corrosion
