Heavy hydrocarbon Petro Part Arka

Crude oil is composed of many hydrocarbons. Hydrocarbons include various organic compounds that are mainly made of carbon C and hydrogen H elements. The bond between the elements in these molecules is a hydrogen-carbon bond, a covalent bond, and in other words, there is no ionic bond in these compounds.

In addition to hydrogen and carbon, other elements such as sulfur S, nitrogen N, and oxygen O are found in crude oil compositions. The higher the amount of sulfur in hydrocarbon compounds, it changes the physical behavior of the compound and makes it non-corrosive. Also, with the increase of sulfur, compounds become heavier and oil refining becomes more difficult. The lower the substitution elements in the hydrocarbons, the lighter and purer the crude oil.
