However, crude oil contains hydrocarbons with carbon numbers that range from C3 to C45+ and is not fully addressed even with the use of all three TPH methods .

Crude oil is a naturally occurring, unrefined petroleum product composed of hydrocarbon deposits and other organic materials.

Crude oil is a naturally occurring, unrefined petroleum product composed of hydrocarbon deposits and other organic materials. A type of fossil fuel, crude oil can be refined to produce usable products such as gasoline, diesel and various forms of petrochemicals. 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. 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. Characteristics of aromatic hydrocarbons in crude oils. The distribution of the methylphenanthrene series reflects the evolution degree of crude oils, MPI holding a positive correlation with In addition to the practically infinite mixtures of hydrocarbon compounds that form crude oil, sulfur, nitrogen, and oxygen are usually present in small but often important quantities. Sulfur is the third most abundant atomic constituent of crude oils. It is present in the medium and heavy fractions of crude oils. Crude oil treatment. We manufacture equipment for crude oil transfer and distribution, such as pig traps, production manifolds and liquid pumping skids. In the upstream oil sector and in parallel with crude oil treatment installations, we design and manufacture installations for the transfer and distribution of crude oil. Midstream activities involve the distribution of crude oil to refiners; the refining of crude oil into saleable products; and the distribution of products to wholesalers and retailers. Examples of firms that would belong in the midstream segment of the industry include companies that transport oil by pipeline, truck or barge (e.g., Magellan Pipeline); and companies that refine crude oil (e.g., Tesoro).

There are, in addition, approximately 1,000 known large oil fields that initially contained between 50 million and 500 million barrels. These fields account for some 14 to 16 percent of the world’s known oil. Less than 5 percent of the known fields originally contained roughly 95 percent of the world’s known oil. Table 2. Composition of crude oil and natural gas. Hydrocarbons. Paraffins: The paraffinic saturated chain type hydrocarbon (aliphatic) molecules in crude oil have the formula C n H 2n+2, and can be either straight chains (normal) or branched chains (isomers) of carbon atoms.The lighter, straight chain paraffin molecules are found in gases and paraffin waxes. Crude oil is a mixture of hydrocarbons that formed from plants and animals that lived millions of years ago. Crude oil is a fossil fuel, and it exists in liquid form in underground pools or reservoirs, in tiny spaces within sedimentary rocks, and near the surface in tar (or oil) sands. Petroleum products are fuels made from crude oil and other hydrocarbons contained in natural gas.
