Polar components in crude oil

Abstract—Heavy Oil Dilution—Heavy crude oils cannot be transported by pipeline without a prior interactions between the solvent and the polar compounds of. Fractionation of Crude Oil Components The highly polar resin fraction did not appear to elute, however, as no corresponding peaks were detectable in either 

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. Denser and more viscous crude oils have greater concentrations of other components, including resins and asphaltenes, which contain more polar compounds,

Impact of Polar Components on Crude Oil-Water interfacial Film Formation: A Mechanisms for Low-Salinity Waterflooding 6 Analysis of Polar Components in Crude Oil by Ambient Mass Spectrometry Chu-Nian Cheng1, Jia-Hong Lai1, Min-Zong Huang1, Jung-Nan Oung2 and Jentaie Shiea1 1Department of Chemistry, National On the other hand, the naturally existing polar components in crude oil such as naphthenic acids, resins and asphaltenes are adsorbed on the interface, which can produce water-in-oil emulsions. Several studies have been accomplished to investigate the effect of different parameters such as temperature, pressure, Resins and asphaltenes are the polar components of crude oil, thus, resins to asphaltenes ratio affects the overall stability of the asphaltenes. Asphaltenes are soluble in aromatic solvents and insoluble in normal alkanes, thus, while the increase in the saturates fraction in crude oil decreases the asphaltene stability, the increase in the aromatics fraction in crude oil reestablishes the stabilization. Polar dimers and polymers (oxidized) These polymers tend to increase the viscosity of the oil. This contributes to the formation of foam, which eases the oxidation, but leaves the product soaking in a greater quantity of oil. The method utilizes both ion exchange and normal phase chromatography to generate fractions of saturated hydrocarbons, aromatic hydrocarbons, basic compounds, naphthenic acids, and other oxygen-containing species, carbazoles, sulfones, and thiophenes from small crude oil samples (∼0.5 g).

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 

how crude oil acts and how it should be handled. Polar components have been found to be one of the most important factors in understanding the physical and chemical behavior of crude oils. Known polar compounds are carboxylic and phenolic acids, organic bases and metal complexes.

Resins and asphaltenes may also be present in crude oil. Resins and asphaltenes are the colored and black components found in oil and are made up of relatively high-molecular-weight, polar, polycyclic, aromatic ring compounds. Pure asphaltenes are nonvolatile, dry, solid, black powders, while resins are heavy liquids or sticky solids with the same volatility as similarly sized hydrocarbons. Saturate, Aromatic, Resin and Asphaltene (SARA) is an analysis method that divides crude oil components according to their polarizability and polarity. The saturate fraction consists of nonpolar material including linear, branched, and cyclic saturated hydrocarbons (paraffins).
