Corrosion Chemistry
Corrosion
Chemistry is a very large area of concern to the industrial sector.
Eugene is a member of the 'North American Corrosion Engineers' society (NACE).
It is here that you will find a large number of Chemists and Chemical
Technologists discussing the chemistry of corrosion. NACE has
informative classes along with standardized corrosion test methods for
many of the industries. Feel free to contact NACE at
http://www.nace.org
for more information about membership.
Corrosion is
a concern, and is treated in almost all other areas, such as Water,
Wastewater, Oilfield, Pulp and Paper, Heat Transfer Fluids, etc...
More areas
that will be added to this section include: Oilfield Downhole Corrosion,
Oilfield Line Corrosion, Microbial Induced Corrosion, and Natural Gas
Dehydration Corrosion to name a few.
A common
acronym for determining factors involving corrosion is SPORTSFAN.
S = Solvent (Is this a polar
or nonpolar solvent)
P = pH (of material)
O = Oxidizing Potential (Are
oxidizers present)
R = Reducing Potential (Are
reducing chemicals such as Hydrogen Sulphide present)
T = Temperature (Increased
temperatures increase corrosion rates)
S = Salts in Solution
(Dissolved chloride salts increase corrosion rates)
F = Fluid flow condition
(Rapid flow rates increase corrosion rates)
A = Agitation (Increased
mixing elevates corrosion rates)
N = New Changes (The aspect
that changed which increased corrosion rates/failure)
