Crude oil chemical components

Due to the complex nature of the crude oil composition, fractionation by chemical properties was used to simplify the characterization of polar compounds. The

Crude oils tend to be a mixture of paraffins-naphthenes-aromatics, with paraffins and naphthenes the predominant species. Fig. 1, although not complete, shows a distribution of crude oil samples obtained worldwide. Geochemical analyses provided the crude’s chemical nature. Crude oil is essentially a mixture of many different hydrocarbons, all of varying lengths and complexities. In order to separate the individual components that make up the raw natural resource, the crude oil must be fractionally distilled so that At the molecular level, crude oil is composed predominantly of carbon, which can make up as much of 87% of the material. Hydrogen is another major component that makes up as much as 13% of crude oil. Other components that are found in crude in varying amounts include oxygen, sulfur, nitrogen, and helium. Chemical Composition Crude oils and refined petroleum products consist largely of hydrocarbons, which are chemicals composed solely of hydrogen and carbon in various molecular arrangements. Crude oils contain hundreds of different hydrocarbons and other organic and inorganic substances including atoms of sulfur, nitrogen, and oxygen, as well as metals such as iron, vanadium, nickel, and chromium. No crude oil has ever been completely separated into its individual components, although many components can be identified. Table 2 lists the more important compounds in a sample of Oklahoma crude. A total of 141 compounds were identified in this oil sample that account for 44% of the total crude volume. The chemical formula for crude oil is C nH 2n+2 , where n is a positive integer. Crude oil is basically a combination of various hydrocarbon molecules, which comprise of hydrogen, H and carbon, C atoms. Among the types of hydrocarbons present in crude oil, alkanes are predominant. The first test in analysis of crude oil for both organic chloride and basic nitrogen contamination is to fractionate a. naphtha boiling fraction (IBP to ~350° for organic chloride) and a kerosene boiling fraction (~350°F to ~525°F for. basic nitrogen and color) from the crude oil.
