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.
