& Paraffin Inhibitor Demand in Oilfield Applications 132
New information is presented on methods for the removal of the adsorbed resinous material from the asphaltene
to produce a better chemically defined core.

precipitation potential," Energy and Fuels, 18(1), pp.
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).
Production Chemicals Market by Type (Demulsifiers, Corrosion Inhibitors, Scale Inhibitors, Asphaltene
Inhibitors, Biocides, Scavengers, Surfactants, and others), by Oilfield Type (Onshore and Offshore), and Region - Global Trend & Forecast to 2020 http://www.
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].
