Benefits of technology

The patent presents a system and method for analyzing crude oil samples to determine various properties such as naphtha and gas oil properties without needing to separate them. These properties help to evaluate the quality of the oil without having to perform extensive and time-consuming crude oil assays. This makes it easier for producers, refiners, and marketers to determine the value of the oil.

Problems solved by technology

Due to the number of distillation cuts and the number of analyses involved, the crude oil assay work-up is both costly and time consuming.
To determine these properties of gas oil or naphtha fractions conventionally, these fractions have to be distilled from the crude oil and then measured / identified using various analytical methods that are laborious, costly and time-consuming.
New rapid, and direct methods to help better understand crude oil compositions and properties from analysis of whole crude oil will save producers, marketers, refiners and / or other crude oil users substantial expense, effort and time.

[0054]A set of constants K and X1-X7 was determined using linear regression for the indicative properties cetane number, pour point, cloud point, aniline point, octane number, and aromaticity. These constants were determined based on known actual distillation data for plural crude oil samples and their corresponding indicative properties. These constants are given in Table 3.

Abstract

A system and a method are provided for calculating the cetane number, pour point, cloud point, aniline point, aromaticity, and / or octane number of a crude oil and its fractions from the density and Fourier transform infrared spectroscopy (FTIR) of a sample of the crude oil.

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...
