Chemical structure of crude oil

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. The distinct physical and chemical properties of diluted bitumen arise from two components: the bitumen provides the high-molecular-weight components that contribute most to density, viscosity, and adhesion; and the diluent contributes the low-molecular-weight compounds that confer volatility and flammability,

The specific chemical structure of oils vary, but they all follow the same basic patterns. They are called triglycerides, because they are made of a glycerol molecule bonded with three hydrocarbon chains, called fatty acids. Although, there are rare cases when triglycerides break down, often through cooking, Refining crude oil involves two kinds of processes to produce the products so essential to modern society. First, there are physical processes which simply refine the crude oil (without altering its molecular structure) into useful products such as lubricating oil or fuel oil. Crude oil characterization has long been an area of concern in refining; however, the need to identify the chemical nature of crude has gained importance in upstream operations. Traditionally, this has been done by simply stating the crude oil gravity, but more information is required to understand the oil well enough to estimate the volume in Abstract. Asphaltenes, the most polar fraction in crude oil, are critical to all aspects of petroleum utilization. The strong interactions between asphaltenes lead to various levels of aggregation, which is responsible for a variety of transportation and upgrading problems. The structure and aggregation of asphaltene have received worldwide concerns, Cannabidiol, or CBD, is one of at least 85 active cannabinoids identified within the Cannabis plant. It is a major phytocannabinoid, accounting for up to 40% of the Cannabis plant's extract, that binds to a wide variety of physiological targets of the endocannabinoid system within the body. Anthracene, also called paranaphthalene or green oil, a solid polycyclic aromatic hydrocarbon (PAH) consisting of three benzene rings derived from coal-tar, is the simplest tricyclic aromatic hydrocarbon. It is on the EPA's priority pollutant list.

Crude oil is a mixture of comparatively volatile liquid hydrocarbons (compounds composed mainly of hydrogen and carbon ), though it also contains some nitrogen, sulfur, and oxygen. Those elements form a large variety of complex molecular structures, some of which cannot be readily identified.

The chemical composition of petroleum varies from oil field to oil field with the petroleum composition effecting the crude oil prices. When combined with other chemicals, oil is the base for over 6,000 items. Petroleum byproducts make tar, asphalt, paraffin wax, and lubricating oils. It is also used  Abstract In this paper, we explore the correlations between the effectiveness of several wax inhibitors and physico-chemical properties of crude oils.

Those elements form a large variety of complex molecular structures, some of which cannot be readily identified. 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. However, raw petroleum or crude oil has characteristic properties and composition.
