Concentrations of iron are
frequently monitored to determine the corrosion rates of equipment
(pipes, pumps, etc) in Oil and Water production.
As the corrosion process
continues, iron dissolves into the liquid from the steel. If a
corrosion program is implemented by a registered chemist through an
inhibitor program, the iron concentration of the water will be reduced.
The reduced iron concentration in the water is due to the lowered rate
of dissolved iron being removed from the steel.
Corrosion inhibitors come in
many varieties, and each has its particular strengths. Some
corrosion inhibitors are excellent under highly corrosive conditions
(acids, dissolved salts, with water), while others excel with protecting
iron from corrosive hydrocarbons.
When determining corrosion
rates due to dissolved iron in produced fluids, background iron
concentrations must be determined.
Another favorable method
gaining popularity is testing for manganese.
