Iron Concentration

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.
