what chemicals are in crude oil
Crude oil is a mixture of comparatively volatile liquidhydrocarbons (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.

What are the organic compounds in crude oil?
Crude oil contains organic compounds, heteroatom compounds (S,N,O), hydrocarbons (C, H), metals and organic (Ni, V, Fe) and inorganic (Na +, Ca ++, Cl -) compounds 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.
What are the hydrocarbons found in crude oil?
There are four main types of hydrocarbons found in crude oil. The hydrocarbons primarily are alkanes, cycloalkanes, and aromatic hydrocarbons. Although there is considerable variation between the ratios of organic molecules, the elemental composition of petroleum is well-defined:
What chemicals are used in the transport of crude oil?
Chemicals are required during the logistical handling and transportation of crude oil in tankers, pipelines or terminals. The flow can be improved in pipelines with the addition of drag reducing agents. Cargoes are stabilized with the help of chemicals such as mercaptan scavengers, pour point depressants and hydrogen sulfide scavengers.
