LIQUID CONDENSATE CORROSION CONTROL FOR BOILER SYSTEMS
RXSOL-50-5005-20 Concentrated liquid neutralising agent for corrosion control in condensate and feed water systems, contain blends of low, medium and high volatility amines that provide great protection and neutralization of acidic gases, such as CO2 throughout a condensate system. Protects boiler surfaces by forming an iron tannate film.
RXSOL-50-5005-20 is a blend of volatile liquid / steam distributions ratios that neutralise the acid contaminants in condensate and feed water thus providing protection against acid corrosion in the complete system.The most common cause of acid corrosion in condensate and feed water systems is dissolved carbon dioxide. Condensate control neutralises this acid and maintains the condensate and feed water in an alkaline condition
FIELDS OF APPLICATIONS :-
RXSOL-50-5005-20 is an effective neutralizing type corrosion inhibitor & oxygen scavanger for steam condensation system. And can also be used to protect Boilers /Metals surfaces form corrosion.It removes oxygen efficiently in open feed systems and gives effective corrosion inhibition of boiler/exhaust gas economizer system surfaces . Its Chemical reaction by converting Fe2O3 (rust) to organic iron compound protect further IRON rust reaction .
OPERATING PROCESS :-
RXSOL-CC72 neutralizes the acid components of feed water.The proportion of RXSOL-50-5005-20 depends upon the Carbon dioxide content of the condensate. Basically RXSOL-50-5005-20 neutralizes the acid contents & maintains the condensate and feed water in the alkaline condition. It also protects copper based metals.
RXSOL-50-5005-20 condensate is tested for PH to determine the dosage level. The PH limits are 8.3 - 9.0 . For an average system e. g. 10 M3, the dosage is approximately 0.65 ltr / day .
The necessary amount of RXSOL-50-5005-20 is required or injected as frequently as to maintain the pH of the condensate at the main condensate pump outlet between 8.6-9.5 . The amines pass over with the steam and have the dual function of elevating the pH of the steam/condensate and putting a protective micro film on the system pipe work. Acidic condensate is the result of carbonic acid (H2CO3) being formed as CO2 is released in the steam.Condensate prevents corrosion by carbonic acid on live systems. Its filming properties also reduce corrosion on shut down lines, when moisture and oxygen are present.
