This is most common Oxygen Treatment Scavanger 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 Treatment Scavanger.
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.
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.
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.)
BENEFITS -
RAPID REACTION :
The catalyst RXSOL-40-5023-210 speeds up the removal of dissolved oxygen. Oxygen can be removed completely even from cold water due to catalytic action. Normal reaction time is as low as 15 to 20 seconds as against 10 to 30 minutes for uncatalysed sulphite.
EASY TO HANDLE :
RXSOL-40-5023-210 is a free flowing powder. It is soluble in water even at lower feed water temperature.It is non-toxic and non-corrosive and, therefore, can be handled easily.
pH CONTROL :
RXSOL-40-5023-210 is formulated to get proper pH control for optimum availability of catalyst for rapid oxygen removal.
COST EFFECTIVE :
The catalytic action reduces the excessive requirement of sulphite in feed water for the rapid removal of oxygen. Thus the quantity required is lower, making RXSOL-40-5023-210 treatment cost effective.
APPLICATION AND DOSAGE :
RXSOL-40-5023-210 solution should be dosed continuously. Dissolve the required quantity of RXSOL-40-5023-210 gently in boiler feed water in a separate tank. Dose this solution continuously in the boiler feed water line after the deaerator.
Above 8 ppm of sodium sulphite is required for the removal of 1 ppm of dissolved oxygen from boiler
feed water. About 10% to 20% of excess sulphite should be dosed to provide oxygen consuming reserve.
The table below gives the approximate dosage.
