Abstract
A method for determining corrosiveness of naphthenic acid in a fluid includes the steps of: providing a fluid containing naphthenic acid; providing iron powder having a surface area of at least about 0.01 m2/g; contacting the fluid and the powder for a period of time so as to provide a portion of the iron as dissolved iron dissolved in the fluid; and measuring iron concentration of the fluid containing the dissolved iron, so as to provide a measure of corrosion potential of the naphthenic acid over the period of time.
Claims19
A method for determining corrosiveness of naphthenic acid in a fluid, comprising the steps of:
- providing a fluid containing naphthenic acid;
- providing iron powder having a surface area of at least about 0.01 m2/g;
- contacting said fluid and said powder for a period of time so as to react a portion of said iron with the naphthenic acid to form iron naphthenate which is soluable in said fluid;
- and
- measuring iron concentration of the iron naphthenate in said fluid containing iron, so as to provide a measure of corrosion potential of said naphthenic acid over said period of time.
