Polar components in crude oil

Due to the complex nature of the crude oil composition, fractionation by chemical properties was used to simplify the characterization of polar compounds. The  Generally, the oxygen content in crude oil fractions increases with the boiling point interval of the fraction. Asphaltenes are a class of very large compounds (  8 Feb 2017 Crude oils were obtained as follows: Alaska North Slope (ANS), Kuwait Blend, and Brent crude from British Petroleum. Bonga crude was provided  Abstract Low salinity waterflooding is a promising Improved Oil Recovery (IOR) process showing growing activity since discovery. However, incremental  The overall polarity of the crude oil is the key to asphaltene stability. Resins and asphaltenes are the polar components of crude oil, thus, resins to asphaltenes 

CRUDE OIL POLARITY Petroleum consists of a complex mixture of substances, the predominant constituents being saturated and aromatic hydrocarbons. Minor components are heteroatomic compounds

Analysis of Polar Components in Crude Oil by Ambient Mass Spectrometry. By Chu-Nian Cheng, Jia-Hong Lai, Min-Zong Huang, Jung-Nan Oung and Jentaie  Crude oils also contain polar organic compounds that contain N, S, and O atoms in various functional groups. The chemical properties of these so-called NSO  5 Aug 1991 Polar compounds in crude oils are responsible for a series of undesirable characteristics that affect the oil industry from the reservoir to the  1 Sep 2015 Polar petroleum components enter marine environments through oil spills Polar crude-oil derived compounds may be more toxic to marine  Maltenes are the n-alkane (pentane or heptane)-soluble molecular components of asphalt, which is the residue remaining after petroleum refiners remove other useful derivatives such as gasoline and kerosene from crude oil The polar compounds are highly reactive petroleum resins that act as a colloidal dispersion   1 Jun 2016 Resins fraction of crude oil comprises polar molecules often containin of fused aromatic rings with branched paraffin and polar compounds.

However, polar compounds comprise only ~15% of crude oil, but are the most problematic for both upstream and downstream processes and therefore their
