OXYGEN SCAVENGING BOILER PITTING PREVENTATIVE

**DESCRIPTION:**
ALKEN® TREATMENT 53 is a free flowing, powder-form, catalyzed and decharacterized oxygen scavenging formula that combines chemically with dissolved oxygen in feedwater or in the boiler to inhibit the formation of oxygen-induced corrosion, including pitting. The effective combination of sodium sulfite and cobalt sulfate, proven effective in Alken® Treatment 52, is here supplemented with sodium lignosulfonate, which contributes less than one percent sodium hydroxide to the finished formula.

ADVANTAGES:

Rapid reaction rate with oxygen
Protects deaerator storage section and feedwater lines
Prevents boiler pitting corrosion

DOSAGES:

Dosage is usually 1/8 to 3/4 lb. of ALKEN® TREATMENT 53 per thousand gallons of boiler feedwater. However, dosages will vary considerably depending upon the feedwater temperature, type of boiler operation, type of heater or deaerator, air leakage into the system, etc.

FEEDING:

ALKEN® TREATMENT 53 is best fed continuously by chemical metering pumps into the deaerator storage section. However, the ordinary boiler treatment feeding methods such as simple shot feeders can be used with diminished effectiveness.

CONTROL:

ALKEN® TREATMENT 53 is normally controlled so that a residual of 30 to 60 mg/L of sodium sulfite is maintained in the boiler water. A Simple test kit should be used to monitor residual sulfite for plant control. Alken-Murray prefers CHEMetrics #K-9610 test kit, but LaMotte & Hach also offer sulfite kits for those who prefer those brands,

PACKAGING:

ALKEN® TREATMENT 53 is packaged in lined fiber drums, holding 100 lbs. or 300 lbs. which conform to Performance Oriented Packaging Specifications. 50 lbs. can be packaged in 5 gallon plastic pails, but a minimum order of 10 pails is required. Store packaging closed, except when opened to extract product, in a cool, dry area.

REGULATORY STATUS::

ALKEN® TREATMENT 53 is formulated in compliance with 21 CFR 184.1139 regulations for boiler water additives used in preparation of steam that will contact food, and was authorized by USDA as category "G6" for use in federally inspected meat and poultry plants, "for use as a boiler water additive, used in the preparation of steam that WILL contact food."
