Ammonium Bisulfite

This is most common oxygen scavengers used to effectively remove dissolved  OXYGEN from your feedwater. Other grades of 5006  has its own advantages depending on your system and personal preferences ) By the presence of dissolved oxygen in water system , corrosion and pitting caused on metal surface. RXSOL 5006 is a specially formulated and  powdered materials.  which, when added to boiler feedwater, removes dissolved oxygen , By acting as an oxygen scavenger. Benefits:- By Control of corrosive oxygen from boiler water which causes corrosion and pitting ,It  improves boiler system long life and  reliability . In boiler feedwater conditioning RXSOL-40-5023-210 is fed to a boiler to remove dissolved oxygen and thus prevent pitting. For the reaction between RXSOL-40-5023-210 and oxygen to proceed rapidly and completely, it is necessary to maintain an excess sulfite concentration at an elevated temperature. Application: The use of RXSOL-40-5023-210 as a chemical deoxygenator is economical within certain limitations imposed by the dissolved oxygen content of the feedwater. If appreciable quantities of dissolved oxygen are permitted to enter the boiler, costs will be high if RXSOL-40-5023-210 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 RXSOL-40-5023-210 to react with the residual oxygen. To prevent corrosion and pitting in feed lines, closed heaters and economizers, it is desirable to feed the RXSOL-40-5023-210 continuously to the boiler feedwater rather than directly to the boiler feedwater rather than directly to the boiler. Reaction between RXSOL-40-5023-210 and oxygen is not instantaneous and the completion of the reaction is aided by the longer contact times provided by feeding RXSOL-40-5023-210 to the feedwater.   Catalyzed RXSOL-40-5023-210 will, however, react almost instantaneously with dissolved oxygen even at cold water temperatures. Because of this property, catalyzed RXSOL-40-5023-210 has found increased use in the treatment of cooling water, process water, distribution system, etc. for preventing oxygen corrosion.  Dose: Theoretically, 7.88 pounds of RXSOL-40-5023-210 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-40-5023-210 are required for each pound of oxygen removed (or 10 ppm RXSOL-40-5023-210 per 1 ppm dissolved oxygen.)Note: TEST METHOD ::: http://rxmarine.com/hydrazine-test-kit   HANDLING, STORAGE AND PRECAUTIONS : RXSOL-40-5023-210 is mildly alkaline in nature. Normal precautions should be taken while handling solid powders. In case of contact, wash with water. Do not swallow. RXSOL-40-5023-210 should be stored in a dry condition. Close the container tightly to avoid contact with air. PACKING : RXSOL-40-5023-210 is available in 50 kg polythene lined bags.
