Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] This application claims the benefit of U.S. Provisional Patent Application No. 62 / 099,679 filed Jan. 5, 2015, the disclosure of which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION

[0002] This invention relates to a method and process for the evaluation of samples of crude oil and its fractions by Fourier transform infrared spectroscopy (FTIR) analysis.BACKGROUND OF THE INVENTION

[0003] Crude oil originates from the decomposition and transformation of aquatic, mainly marine, living organisms and / or land plants that became buried under successive layers of mud and silt some 15-500 million years ago. They are essentially very complex mixtures of many thousands of different hydrocarbons. Depending on the source, the oil predominantly contains various proportions of straight and branched-chain paraffins, cycloparaffins, and naphthenic, aromatic, and polynuclear aromatic hydrocarbons. These hydrocarbons can be gaseous, l...
