Characteristics of Crude Oil •The hydrocarbons in crude oil can generally be divided into four categories: •Aromatics: These can constitute anywhere from 3 to 30% of crude. •They are undesirable because burning results in soot. •They are also more viscous. They are often solid or semi-solid. •Asphaltics: These average about 6% in most crude. 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 different forms in oxygen-bearing resinous substances. There are, however, some general relationships of crude oil composition that can be derived from pour point and viscosity data. Commonly, the lower the pour point of a crude oil the more aromatic it is, and the higher the pour point the more paraffinic it is.Viscosity is usually determined at different temperatures (e.g., Chemical Constitution of Crude Oil. Print. Crude oil contains organic and inorganic compounds and species 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. Agency), is an organization that has been dedicated to performing oil and chemical spill research since 1973. Since 1984, Environment Canada has been analyzing crude oils and oil products to determine not only basic physical properties, but also how oil behaves when spilled in the environment. A ‘catalogue’ of oil properties, rise to the enormous deposits of oil found in that region of the world. Properties of Petroleum The elemental composition of petroleum is much less variable than that of coal: 83-87% carbon, 11-16% hydrogen, 0-4% oxygen plus nitrogen, and 0-4% sulfur. Note that most crude oils contain substantially more hydrogen than coals. Only a brief discussion is Because the ultralight crudes and gas condensates are less dense and less viscous than synthetic crude oil, diluent-to-bitumen ratios are roughly 30:70. The particular mixture of light hydrocarbons in the diluent can be important in spill response. If the diluent is dominated by lighter compounds (C 4 -C 8 ),
