OXYGEN SCAVENGER
RXSOL-40-5025-025 is a catalysed oxygen scavenger in powder form. It is a blend of sodium sulphite and a catalyst. It is recommended for the rapid and complete removal of dissolved oxygen from boiler feed water. RXSOL-40-5025-025 reacts with oxygen to produce sodium sulphate, which contributes to the dissolved solids in boiler feed water. (Na2SO3 + ½ O2 = Na2SO4).
RXSOL-40-5025-025 solution should be dosed continuously. Dissolve the required quantity of RXSOL-40-5025-025 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.
