Conversely, heavy crude oil is thick and dense, containing a higher concentration of large, complex molecules that are difficult to extract and refine. It contains various impurities that are classified as contaminants.
Understanding Oil Contaminants and Impurities in Crude Oil
Paraffins: Straight-chain molecules that are usually the most abundant, determining the oil's volatility and energy content. The majority of compounds found in crude oil fall into two categories: aliphatics and aromatics.
The geographical origin of the oil dictates its molecular weight, sulfur content, and API gravity, which in turn dictates its market value and intended use. From Organic Matter to Kerogen As the buried organic layer accumulated under increasing pressure and heat, a complex chemical transformation occurred.
Understanding Oil Contaminants and Impurities in Crude Oil
Light crude oil contains a high percentage of small, volatile hydrocarbons, making it easier to refine and more valuable for gasoline production. Understanding what oil is made out of requires a journey back millions of years to explore the biological origins and the intricate molecular composition that defines this essential resource.
