Components of crude petroleum oil
Elemental Composition of Petroleum. Carbon - 83 to 87%. Hydrogen - 10 to 14%. Nitrogen - 0.1 to 2%. Oxygen - 0.05 to 1.5%. Sulfur - 0.05 to 6.0%. Metals - < 0.1%. 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 largest volume products of the industry are fuel oil and gasoline. Petroleum is also the raw material for many chemical products, including pharmaceuticals, solvents, fertilizers, pesticides, and plastics. The industry is usually divided into three major components: upstream, midstream and downstream. The molecules can have the shape of chains, branching chains, rings or other structures. Petroleum is a complex mixture of hydrocarbons. The most common hydrocarbons are natural gas, crude oil and coal. 1.3k views · View 3 Upvoters 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. Composition of Petroleum. Petroleum is essentially a mixture of hydrocarbons particularly alkanes, cycloalkanes and aromatic hydrocarbons. Apart from hydrocarbons it may also contain compounds containing oxygen and nitrogen. The exact composition of crude oil varies from one place to another and from one oil field to another.

Apart from hydrocarbons it may also contain compounds containing oxygen and nitrogen. The exact composition of crude oil varies from one place to another and from one oil field to another. Composition of Crude Oil. 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%. 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, Less dense (lighter) crude oils generally have a higher share of light hydrocarbons. Refineries can produce high-value products such as gasoline, diesel fuel, and jet fuel from light crude oil with simple distillation. When refineries use simple distillation on denser (heavier) crude oils, Although the composition of petroleum will contain many trace elements the key compounds are carbon (93% – 97%), hydrogen (10% - 14%), nitrogen (0.1% - 2%), oxygen (01.% - 1.5%) and sulphur (0.5% - 6%) with a few trace metals making up a very small percentage of the petroleum composition. 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.
Crude oil refers to liquid petroleum as opposed to refined oil. The components of crude oil can be classified into two hydrocarbon series: methane series and
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. Each crude oil has a unique composition and set of physical properties which are delineated by crude oil assays performed in petroleum laboratories. Some of the common petroleum crude oils (many of which are known as benchmark crude oils) are: West Texas Intermediate is a very high-quality, sweet, light oil. It is a North American oil. After crude oil is removed from the ground, it is sent to a refinery where different parts of the crude oil are separated into useable petroleum products. These petroleum products include gasoline, distillates such as diesel fuel and heating oil, jet fuel, petrochemical feedstocks, waxes, lubricating oils, and asphalt. The most widely used correlations treat the oil and gas phases as a two-component system. Only the pressure, temperature, specific gravity, and relative amount of each component are used to characterize the oil’s PVT properties. Crude oil systems from various oil-producing regions of the world were used in the development of the correlations. Crude Oil 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. On average, crude oils are made of the following elements or compounds: Carbon - 84%. Hydrogen - 14%. Sulfur - 1 to 3% (hydrogen sulfide, sulfides, disulfides, elemental sulfur). Nitrogen - less than 1% (basic compounds with amine groups). Oxygen - less than 1% (found in organic compounds such The process of fractional distillation is used to separate crude oil into its main components (ie. its relevant carbon chain length).

The cracking of the large hydrocarbons, thermally or The various components of crude oil have different sizes, weights and boiling temperatures; so, the first step is to separate these components. Because they have different boiling temperatures, they can be separated easily by a process called fractional distillation. Crude Oil. Except the gas component in the petroleum, the rest of the mixture is known as crude oil. It is a liquid. Alkanes, cycloalkanes, aromatic hydrocarbons are mainly found in crude oil. There are other organic compounds containing nitrogen, oxygen, sulfur and other metals. The appearance of crude oil may differ due to the composition of it.
