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.
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 Sodium Bisulphate as a chemical deoxygenator is economical within certain limitations imposed by the dissolved oxygen content. Sodium Bisulphate 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 Sodium Bisulphate to react with the residual oxygen.
To prevent corrosion and pitting it is desirable to feed the Sodium Bisulphate. Oxygen scavengers capture the dissolved oxygen in a harmless chemical reaction that renders the oxygen unavailable for corrosive reactions.
Theoretically, 7.88 pounds of RXSOL-44-6119-250 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-44-6119-250 are required for each pound of oxygen removed (or 10 ppm RXSOL-40-5023-210 per 1 ppm dissolved oxygen.)

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
