  • METHODS FOR PREDICTING CORROSION RATE OF CRUDE OIL DERIVED SAMPLES USING X-RAY ABSORPTION SPECTROSCOPY
    Publication number: 20160349198
    Abstract: A method for predicting the corrosion rate of crude oil or other related process streams is provided. The method includes using x-ray absorption spectroscopy to characterize heteroatom species present by functional group and quantify the relative amount of each species in a plurality of samples. The corrosion rate of each sample is measured. A correlation between the relative amount of each species and the corrosion rate is determined and used to create a corrosion prediction model. The corrosion prediction model can be used so that corrosion rate can be predicted for a sample solely from the spectroscopy measurement of the relative amounts of each relevant species.
