Crude oil classification based on viscosity

Most of the multivariate predictions reported on crude oil properties are based on utility of PCA in pattern recognition and classification of vast amount of data,  10 Aug 2017 General crude oil classification according to density and viscosity. Display full size. 27 Apr 2017 Among the different compounds of crude oil, asphaltenes are usually most ( 2016) reported the use of oil-based nanofluids for viscosity reduction according to the most recent IUPAC classification (Thommes et al., 2015).

Other classification methods: Chromatographic data - classification of crude oil on the basis of polarity Gas chromatography, Fourier transform infrared spectroscopy, proton magnetic resonance, urea adduction, and solid liquid chromatograph y – classification of petroleum wax Pyrolysis–gas chromatography - classification of kerogen where V(100°F) is the viscosity in SUS and SG is the specific gravity at 15.6°C (60°F). VGC varies between 0.74 to 0.75 for paraffinic, 0.89 and 0,94 for naphthenic, and 0.95 and 1.13 for aromatic hydrocarbons. The U.S. Bureau of Mines Correlation Index (BMCI) or (CI) is useful for characterization of crude oil fractions. Physical and Chemical Properties of Crude Oil and Oil Products 1- Density, Specific Gravity, and API Gravity Density is defined as mass per unit volume of a fluid. Density is a state function and for a pure compound depends on both temperature and pressure and is shown by ρ. Liquid Volatilized oil also is called lease condensate or distillate. Gas condensates and wet gases also contain volatilized oil. Volatilized oil is reported conventionally as part of the crude-oil reserves and production. It should not be confused with and is distinctly different from natural-gas liquids. API FA-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase.

TRF has also been used to characterize of crude oil in Ref. And the viscosity of lube base oils is defined by the molecular size as shown in Figure For automotive lubricants, empirical SAE Viscosity Classification (SAE of base oils produced from Gulf Coast crude oil with poor viscosity-temperature  Basically, the composition of mineral oil is greatly influenced by the crude oil used for the first time. 3. Base oil classification according to viscosity index 

A heavy hydrocarbon, oil-in-water emulsion that has a relatively low viscosity for improved transport is disclosed. View 2 more classifications The invention is directed to heavy crude oil emulsions, fuel oil emulsions, and the like, and the In addition, according to this invention, a diffuser is attached to the end of pipes 

(I-3.5) Classification by viscosity. 16 carbon dioxide, polymers, and solvents to reduce crude oil viscosity. Classification according to chemical composition. environmentally friendly base oils with high viscosity index. To reach these In the experimental section of this paper the results of hydroisomerization of wax from Hungarian crude oil on Table 1 shows the API classification of base oils [5 ]. 19 Jun 2016 The composition of crude oils can vary greatly depending on oil quality, by increasing its density, viscosity, TAN, asphaltene and sulphur content, among other [7-8,. 18]. using the API classification in section 2.2.1. Crude  Oil types differ from each other in their viscosity, volatility, and toxicity. Viscosity refers to an Group 3: Medium Oils (Most Crude Oils, IFO 180). About one-third

API FA-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase. Classification of Crude Oil: Viscosity. Viscosity of crude oil is the internal friction of a liquid. Its evaluation involves assessing the thickness of the substance. Based on its viscosity, crude oil is classified 4 factors of crude oil classification. Viscosity defines the ability of oils to flow. Higher viscosity makes oil more difficult to flow. As such, it takes much energy to pump it from the ground. Volatility defines the speed of oil evaporation. Higher volatility requires additional measures to monitor the environment during the extraction An engine in a colder climate, where motor oil tends to thicken because of lower temperatures, would benefit from 0W or 5W viscosity. A car in Death Valley would need a higher number to keep the oil from thinning out too much. The second number after the "W" indicates the oil's viscosity measured at 212 degrees Fahrenheit (100 degrees Celsius).

1 Jun 2017 Crude oil viscosity can be categorised into three classes depending on of multiple base models of classifiers or regressors for classification 

Official Classifications. In 1993, the American Petroleum Institute (API), categorized base oils into five main groups. This breakdown is based on the refining method and the base oil’s properties in terms of, among other things, viscosity and the proportion of saturates and sulfur content.

Beal’s method was developed from observations of dead oil viscosity at 100 and 200°F and has a tendency to underpredict viscosity at high temperature. Dead oil viscosity correlations are somewhat inaccurate because they fail to take into account the chemical nature of the crude oil. Other classification methods: Chromatographic data - classification of crude oil on the basis of polarity Gas chromatography, Fourier transform infrared spectroscopy, proton magnetic resonance, urea adduction, and solid liquid chromatograph y – classification of petroleum wax Pyrolysis–gas chromatography - classification of kerogen where V(100°F) is the viscosity in SUS and SG is the specific gravity at 15.6°C (60°F). VGC varies between 0.74 to 0.75 for paraffinic, 0.89 and 0,94 for naphthenic, and 0.95 and 1.13 for aromatic hydrocarbons. The U.S. Bureau of Mines Correlation Index (BMCI) or (CI) is useful for characterization of crude oil fractions.
