Concentrations of manganese are
monitored to determine the corrosion rates of equipment
(pipes, pumps, etc) in Oil and Water production.
As the corrosion process
continues, manganese dissolves into the liquid from the steel. If a
corrosion program is implemented by a registered chemist through an
inhibitor program, the manganese concentration of the water will be reduced.
The reduced manganese 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 manganese
concentrations must be determined, and are significantly more reliable
than iron concentrations.
for testing corrosion rate is monitoring iron concentrations.
