VOLATILE CORROSION INHIBITOR

• Inhibits steam-condensate corrosion caused by carbon dioxide and/or dissolved oxygen. Suited for steam systems which do not include complex medium to long and/or branched steam systems. Ideal for short runs including boiler-room machinery.
• Inhibits corrosion in vapor-phase processes such as certain refinery processes and in some waste oil recovery operations. Provides corrosion protection where chloride, sulfide, sulfate, carbon dioxide, and organic acids are present.
• Provides corrosion protection to cold-end equipment in the flue gas systems of gas-fired boilers and furnaces. Carbonic acid and sulfuric acid corrosion can be severe in such equipment, especially in very high efficiency installations which operate at or near condensation conditions.
  
  

When used to protect a steam system, ALKEN® TREATMENT F-629 may be added separately to the deaerator storage section, feed-water tank, feedwater line, or directly to the boiler with other boiler treatment chemicals.

When used to protect equipment in a vapor-phase process, or in a flue gas system, ALKEN® TREATMENT F-629 should be injected continuously into the gas stream and/or the wash water (if used).

The required dosage of ALKEN® TREATMENT F-629, when used as a steam/condensate corrosion inhibitor, can be estimated at 10-15 ppm in the steam.

The required dosage of ALKEN® TREATMENT F-629, when used as vapor-phase process corrosion inhibitor, can be estimated at 25-50 ppm in the vapor. This initial estimate may have to be adjusted upward or downward by to a considerable extent depending on the nature of the process.

The required dosage of ALKEN® TREATMENT F-629, when used as a flue-gas corrosion inhibitor, can be estimated at 1 gallon per 750,000 cu. ft. of natural gas burned.

ALKEN® TREATMENT F-629 is shipped in containers complying with Performance Oriented Packaging Specifications. Consult the current Material Safety Data Sheet for storage and handling precautions.
