Abstract

Crude oil is used widely among refineries to produce products that are useful to the public. However, due to the increased popularity of harvesting crude oil from tar sands and other unmanned wells, more polar toxins are expected to be present in these mixtures and thus make it difficult for the refinery processing. As a part of the efforts to develop an analytical procedure based on MRR for fast detection of polar impurities in the oil mixture, a benchtop K-Band molecular rotational resonance spectrometer, which operates in the 18-26GHz frequency range, has been employed to record rotationally resolved spectra of crude oil. Preliminary analysis of the observed rotational spectra reveals the presence of multiple polar toxins, including small Sulfur-Oxygen-Nitrogen containing compounds, due to K-Band MRR’s sensitivity to only small polar compounds. The complex hydrocarbon matrix, which in many chromatographic methods obscures the signals from low concentration impurities, is eliminated. Plans to improve this analytical procedure are underway and results will be given in this talk.
