Abstract A series of experimental viscosity data for seven different North Sea oils is presented. A new corresponding states method for prediction of the viscosity of both gaseous and liquid hydrocarbon fluids has been developed. The required input is critical constants and the molecular weight of each component.

Bioinspired Solar‐Heated Carbon Absorbent for Efficient Cleanup of Highly Viscous Crude Oil
Advanced Functional Materials, 2019Efficient cleanup of viscous crude oil spill is a worldwide challenge due to its sluggish flowability at room temperature. Conventional oil remediation methods using physical absorbers, skimmers, and vacuum technologies either demonstrate low absorption ...

Due to highly adhesive property, crude oil is easier to adhere on foul filtration membranes. Separation of crude oil‐in‐water emulsion is a continuing tough work. Hydrogels with low‐adhesive superoleophobicity are ideal materials for modifying filtration

The recovery of heavy crude oil is limited because of the high interfacial tension (IFT) between the crude oil and aqueous phase, which restricts the extent of emulsification and results in poor mobility.

Oil has been the number one source of energy in the world since the middle of the twentieth century. The world is very dependent on petroleum for transportation fuels, petrochemicals and asphalt. But ever increasing demand has caused the price of oil to spike in recent years, and only the world economic crisis has been able to temper demand and bring ...

Alkyldiphenylmethanes in Crude Oils
Polycyclic Aromatic Compounds, 1996Abstract GC-HRMS was used for the analysis of alkyldiphenylmethanes in crude oil. Diphenylmethane and four isomeric methyldiphenylmethanes were identified in crude oils by comparison of their mass spectra and chromatographic behaviour with authentic standards.
