Claim Text:
1. A method for predicting a corrosion rate of a crude oil derived sample, comprising: a. creating a corrosion prediction model, including the steps of: b. subjecting the crude oil derived sample for which a corrosion rate prediction is desired to a range of x-ray energies to obtain x-ray absorption fine structure data in the form of absorbance versus x-ray energy; c. identifying functional groups present in the crude oil derived sample from the x-ray absorption fine structure data; d. quantifying relative amounts of the functional groups identified in the crude oil derived sample; and e. solving the corrosion prediction model for corrosion rate as a function of the relative amounts of the functional groups identified in the crude oil derived sample to obtain a prediction of the corrosion rate of the crude oil derived sample.
