Applications

Boiler Feedwater Treatment: Used for pH adjustment and control of acidic conditions in compatible boiler feedwater systems.

Steam Distribution Networks: Helps protect piping and associated equipment against carbonic acid corrosion.

Condensate Return Systems: Maintains suitable condensate pH to reduce corrosion and iron contamination.

Industrial Steam Plants: Applicable to power generation, petrochemical, refinery and manufacturing steam systems, subject to system-specific treatment requirements.

RXSOL-50-5005-025 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
Used in medium and high-pressure boilers including ultra high-pressure boilers.

Fields Of Application:-
RXSOL-50-5005-025 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-50-5005-025 depends upon the Carbon dioxide content of the condensate. Basically RXSOL-50-5005-025 neutralizes the acid contents & maintains the condensate and feed water in the alkaline condition.  It also protects copper based metals.

Recommended Dosing Procedure

Inject the neutralizing amine into a suitable feedwater or condensate treatment injection point using a calibrated chemical dosing pump.

The dosage should be established from condensate pH, carbon dioxide loading, feedwater quality, steam distribution characteristics and operating conditions.

A typical condensate pH target may be approximately 8.5–9.2, but the correct range depends on system metallurgy, particularly the presence of copper alloys, and the applicable equipment specifications.

Monitor condensate pH, iron and copper concentrations, and treatment residuals to optimize dosing.

RXSOL-51-5005-210 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-51-5005-210 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.

Technical Specifications

These are the requested target specifications, not independently verified finished-product test results.

We carry a complete line of condensate treatment chemicals.  Condensate treatment chemicals are used to increase the condensate pH, thus reducing corrosion to the entire boiler steam system.  The most common product is a tri-blend amine of cyclohexylamine, morpholine, and diethylaminoethanol (DEAE) neutralizing amines, although we do have standard RXSOL products or we can custom blend to your needs.
