Ammonium Bisulfite Oxygen Scavenger

Description

This is most common oxygen 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.

Product Technical bulletin

OXYGEN SCAVENGER

RXSOL-40-5023-210  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-40-5023-210 reacts with oxygen to produce sodium sulphate, which contributes to the dissolved solids in boiler feed water. (Na2SO3 + ½ O2  Na2SO4).

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.

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.
