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 m,/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.
