Notes & Precautions

BENEFITS -

RAPID REACTION :

The catalyst RXSOL-81-6119-220 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-81-6119-220 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-81-6119-220 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-81-6119-220 treatment cost effective.

APPLICATION AND DOSAGE :

RXSOL-81-6119-220 solution should be dosed continuously. Dissolve the required quantity of RXSOL-81-6119-220 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.

Industry Applications

Why Hydrazine is replace by Carbohydrazide ?
Carbohydrazide (CH6N4O) - RXSOL-42-2541-025 is an oxygen scavenger often added to boiler systems to control corrosion. It reacts with oxygen at low temperatures and pressures. It also passivates metal surfaces preventing further corrosion. The reaction products are volatile, so they do not contribute to dissolved solids in the system. Carbohydrazide is widely used to replace hydrazine as an oxygen scavenger because it is less toxic.
