DESCRIPTION
AND USE
FM***1 is a
primary filming amine designed to reduce corrosion in condensate
systems.
The product
establishes a protective barrier on metal surfaces, thus inhibiting
the corrosive effects of oxygen and carbon dioxide).
FM***1 is
applied directly to the steam header for prevention of return line
corrosion due to
carbon dioxide
and oxygen.
Corrosivity of
condensate is a function of the quantity of oxygen and carbon
dioxide present in the steam. Feedwater alkalinity decomposes in
the boiler to produce carbon dioxide that is evolved with the
steam.
When the steam
condenses, carbon dioxide gas dissolves in water to form carbonic
acid. Carbonic acid promotes low pH attack of piping surfaces,
resulting in damaging metal loss. Oxygen intrusion into the system
is mainly through leakage in areas of vacuum condensation and at
pump seals.
Control of
return line corrosion can be achieved by application of filming
amines. These high molecular weight, organic materials form a
protective monomolecular film on the base metal of the condensate
system. One end of the highly polar amine molecule attaches itself
to the metal surface, while the other end provides the
water-repelling barrier. The most effective filming amines are
primary, straight-chained materials.
TREATMENT AND
FEEDING REQUIREMENTS
Feed FM***1
continuously, directly to the steam header.
Normal
feedrates are between *0 and *0 lb of product per million pounds (1
and 2 kg per **0 tonnes) of steam.
Dilute the
product to 5 to *0% with warm condensate at **0° to **0°F (*0° to
*1°C). Do not use raw water or boiler water. Do not mix with other
chemicals.
The feeding
equipment should include: stainless steel tank; stainless steel
agitator; stainless steel relief valve; iron piping, valves and
fittings; and a pump with machined steel or cast iron liquid end
and stainless steel trim. Filming amines should be fed using an
injection nozzle for vapor streams.
