asphaltene

[a′sfȯl‚tēn]
(materials)
Any of the dark, solid constituents of crude oils and other bitumens which are soluble in carbon disulfide but insoluble in paraffin naphthas; they hold most of the organic constituents of bitumens.

New information is presented on methods for the removal of the adsorbed resinous material from the asphaltene to produce a better chemically defined core.

This unique technology brings us innovative chemistries to address challenges in flow assurance, particularly paraffin wax and asphaltene formation inhibition, as well as solutions for hydrocarbon recovery, reclamation, liquefaction, demulsification, separation, storage and transport vessel hydrocarbon sludge removal.
DAO from the ROSEA units contain the lowest possible quantities of asphaltene which help in reducing catalyst consumption and will improve performance of the downstream hydroprocessing units.
Bitumen is usually regarded as a colloidal suspension of asphaltene particles sound by resin in an oily continuous matrix.
The word asphaltene was coined by Boussingault in 1837 when he noticed that the distillation residue of some bitumen had asphalt-like properties.
Thus, residue fluidized catalytic cracking (RFCC) is limited in terms of its applicability to process relatively low metal and low asphaltene feeds (Shen et al.
E4EOR solvents have the ability to inhibit buildup of unwanted asphaltene solids and paraffin wax precipitants whose high molecular weights choke the flow of oil by not only plugging wellbore-tubing and surface-equipment, but also they clog and block reservoir pore-space around injection wells and production wells (preventing EOR injectants from reaching and dislodging the stranded oil targeted behind the blocked pores).

The type of deposit that forms in the pipeline--iron sulfate, mineral scales, bacteria, paraffin, black powder, asphaltene, degraded compressor oil, amines, and glycol, to name a few--also affects pigging decisions.
It indicates that at such high temperature in molten asphalt PPO could be synthesized from DMP with collaboration of vanadium and some amines in asphaltene of asphalt such as TMEDA-like amino compounds [27, 28].
