Hydrocarbon components of crude oil

Crude oils are mixtures of hydrocarbon compounds ranging from smaller, volatile compounds to very large, nonvolatile compounds. The hydrocarbon structures found in oil include saturates, aromatics, and polar compounds that include resins and asphaltenes. The resins and asphaltenes are largely recalcitrant in the environment. A hydrocarbon is an organic compound composed of two elements, hydrogen and carbon. A large part of the composition of petroleum is made up of hydrocarbons of varying lengths. The smallest hydrocarbon, methane, is composed of a single carbon atom and four hydrogen atoms.

Crude oils are mixtures of hydrocarbon compounds ranging from smaller, volatile compounds to very large, nonvolatile compounds. The hydrocarbon structures found in oil include saturates, aromatics, and polar compounds that include resins and asphaltenes. The resins and asphaltenes are largely recalcitrant in the environment.

The main process for separating the hydrocarbon components of crude oil is fractional distillation. Crude oil fractions separated by distillation are passed on for subsequent processing into numerous products, ranging from gasoline and diesel fuel to heating oil to asphalt. Given the pattern of modern demand (which tends to be highest for transportation fuels such as gasoline), the market value of a crude oil generally rises with increasing yields of light products. The hydrocarbons primarily are alkanes, cycloalkanes, and aromatic hydrocarbons. Elemental Composition of Petroleum Although there is considerable variation between the ratios of organic molecules, the elemental composition of petroleum is well-defined: The hydrocarbons in crude oil are mostly alkanes, cycloalkanes and various aromatic hydrocarbons, while the other organic compounds contain nitrogen, oxygen and sulfur, and trace amounts of metals such as iron, nickel, copper and vanadium. Many oil reservoirs contain live bacteria. Crude oil consists of a complex mixture of hydrocarbons of various molecular weights. In addition, nitrogen, oxygen, and sulfur occur in small quantities. The hydrocarbons consist of alkanes (paraffins) and cycloalkanes (naphthalenes), which are saturated hydrocarbons with straight or branched chains of hydrocarbon molecules. Crude oil mixtures are mainly made up of straight chain hydrocarbon molecules, the bulk of which are paraffins. Paraffins included in crude oil are typically methane to decane, with C1-C4 being removed before further processing by processing means. Crude oil may contain olefins, an alkene chain, Hydrocarbons contain a lot of energy. Many of the things derived from crude oil like gasoline, diesel fuel, paraffin wax and so on take advantage of this energy. Hydrocarbons can take on many different forms. The smallest hydrocarbon is methane (CH 4), which is a gas that is a lighter than air. Longer chains with 5 or more carbons are liquids. Crude oil is a natural multicomponent mixture. Its major part is composed of hydrocarbons (alkanes, naphthenes, and aromatics). Their content in oils ranges between 30% and 100%. Most important among the non-hydrocarbon components are resins and asphaltenes.
