For example, HFO fuels usually with high aromatic hydrocarbons and asphaltenes
may create precipitate like heavy mud as mixing, so it causes the obstruction.
have been shown to exhibit polymeric behavior, be soluble in aromatics and longer straight-chain hydrocarbons, and insoluble in alcohols and water, increase viscosity and stiffness, and harden softer petroleum fractions.
DW Liquid ROS changed the surface structure of paraffin and asphaltenes
so that it would not form a deposit.
Li, Composition and Structure Changes of Asphaltenes
from Medium and Low Temperature Coal Tar Before and After Hydrotreating, J.
Development in Petroleum Science Asphaltenes
Determination of the nitrogen chemical structures in petroleum asphaltenes
using XANES spectroscopy.
With an established track record of resolving a multitude of blockages comprised of hydrates, scale, paraffin, and asphaltenes
, the eelReel Tool is a solution for remediation of pipeline blockages and production restoration.
The heated solvent dissolves the bitumen, but leaves behind unwanted materials such as coke-forming asphaltenes
, sulphur and heavy metals.
Cleaning pipelines not only helps prevent corrosion but also reduces the build-up of a host of deposits, such as salts and scales, corrosion products (including black powder), paraffin wax, asphaltenes
, hydrates, sand and well fines, napthenates, emulsions, sludge and water.
Refinery residues and asphaltenes
have high viscosity and possess similar properties of high sulphur content and presence of metals as petcoke.
The Maze microfluidic SARA analysis fully automates the process for testing oil samples for saturates, aromatics, resins and asphaltenes
(SARA)coupling novel microfluidic technology with spectroscopy.
V and Ni electrochemical deposition from asphaltenes
in heavy oils
