appreciable amount of the naphthene compounds, (10% by composition). Crude oils also contain a great variety of heteroatomic chemical constituents, comprising of crude oil. The A.Psulphur, oxygen, carbondioxide, nitrogen and trace metals. Nitrogen varies from 0.01 to 2%. as d. issolved gas in the crude oil (Levinson, 1974). Oxygen occurs in Petroleum is a complex mixture of organic compounds, all of which provide clues to some aspect of its origin, burial in sediments and chemical modification. A porphyrin is one such chemical that is found in crude oil and also in plants and blood. Interestingly, porphyrins break down rapidly in the presence of oxygen or other oxidizing conditions. Geologists often suggest that porphyrins are evidence for widespread reducing environments during the deposition of petroleum source rocks. However

Crude oil contains organic compounds, heteroatom compounds (S,N,O), hydrocarbons (C, H), metals and organic (Ni, V, Fe) and inorganic (Na +, Ca ++, Cl-) compounds as listed in Figure 1.7. Compounds that contain only elements of carbon and hydrogen are called hydrocarbons and constitute the largest group of organic compounds found in petroleum. Crude oils are customarily characterized by the type of hydrocarbon compound that is most prevalent in them: paraffins, naphthenes, and aromatics. Paraffins are the most common hydrocarbons in crude oil; certain liquid paraffins are the major constituents of gasoline (petrol) and are therefore highly valued. Chemical Composition of Petroleum Petroleum or crude oil is a complex mixture of hydrocarbons and other chemicals. The composition varies widely depending on where and how the petroleum was formed. In fact, chemical analysis can be used to fingerprint the source of petroleum. Explain how the different chemical compounds in crude oil are separated? Answer. Wiki User November 15, 2011 4:39PM. Crude oil is distilled, producing different fractions at different temperatures. Crude Oil. Crude oil is predominantly a mixture of straight and branched chain aliphatic hydrocarbons, ranging from gaseous methane to viscous tar-like compounds with up to 80 carbons.

Related terms: Biodiesel; Petroleum Product; Hydrocarbon; Natural Gas; Oil Spill; Petroleum; Polycyclic Aromatic Hydrocarbon; Biomarker 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.

Among the types of hydrocarbons present in crude oil, alkanes are predominant. Crude oil is a dark, oily liquid that is usually found naturally in underground reservoirs, pools, and tar sands. It is a fossil fuel that is extracted and used to make petroleum products. Crude oil is refined to make gasoline , diesel fuel , jet fuel, residential fuel oil, kerosene, propane , and other sources of energy. Though crude oil is predominantly composed of various hydrocarbons, certain nitrogen heterocyclic compounds, such as pyridine, picoline, and quinoline are reported as contaminants associated with crude oil, as well as facilities processing oil shale or coal, and have also been found at legacy wood treatment sites. These compounds have a very high water solubility, and thus tend to dissolve and move with water. Crude oil is an important source of: fuels such as petrol, diesel, kerosene, heavy fuel oil and liquefied petroleum gases feedstock for the petrochemical industry

Crude oil is an important source of: fuels such as petrol, diesel, kerosene, heavy fuel oil and liquefied petroleum gases feedstock for the petrochemical industry The more toxic compounds in crude oil are aromatic chemicals—a subset of organic compounds that share a common chemical structure, namely, at least one benzene ring. These include mono-aromatic volatile organic compounds (VOCs) such as benzene, toluene, ethylbenzene, and xylenes (BTEX). Chemical compounds are substances that are formed from two or more different chemical elements. These substances, the compounds, can be "taken apart" or separated by chemical reactions. A chemical element, on the other hand, is one or more atoms of a single type or kind of atom. Fixed oils and fats have the same chemical composition: they consist chiefly of glycerides, resulting from a reaction between an alcohol called glycerol and certain members of a group of compounds known as fatty acids.
