Advanced Chemical Engineering, Volume 1, Issue 1, July 2026.The study maps molecular force fields to three‐component solubility parameters (δd, δp, and δhb). Solvent behavior reflects the competition between physical effects and hydrogen‐bond network evolution. Crucially, fluid density determines the absolute magnitude of cohesive interactions, whereas temperature functions as a key variable to selectively ...

A New Approach to Determine Asphaltenes Stability
, 2017 Asphaltenes stability is a phase behavior phenomenon and affected mainly by the change in pressure and temperature. However, the changes in pressure and temperature lead compositional changes, hence, the dependency of asphaltenes stability on crude oil ...

The Canadian Journal of Chemical Engineering, Volume 104, Issue 6, Page 2940-2957, June 2026.Surfactant‐modified nanoparticles adsorb at the oil–water interface, enabling interfacial stabilization and microemulsion formation. Abstract This study systematically investigated the interfacial behaviour of silicon dioxide (SiO2) and aluminium oxide (Al2O3) nanoparticles (NPs) functionalized with cationic (CTAB), anionic (SDS), and nonionic (Triton ...

Resonance‐induced restoration of rock permeability degraded by heavy components of crude oil
Deep Underground Science and Engineering, Volume 5, Issue 2, Page 556-566, June 2026.Resonance‐induced changes occur in filtration properties of sedimentary rocks in crude paraffin oil flow under acoustic vibrations. Experimental data on (a) pressure drop; (b) permeability; (c) pressure at the rock inlet; and (d) pressure at the rock outlet are presented.

The Fractal Aggregation of Asphaltenes
, 2016 This paper discusses time-resolved small-angle neutron scattering results that were used to investigate asphaltene structure and stability with and without a precipitant added in both crude oil and model oil.

Terrestrial Analogs to Titan for Geophysical Research
Reviews of Geophysics, Volume 64, Issue 2, June 2026.Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Study of Asphaltene Structure Precipitated from Oil Sands
Eurasian Chemico-Technological Journal, 2013 In the paper microscopic structure and physicochemical characteristics of asphaltenes were investigated. Asphaltene was precipitated from natural bitumen of oil sand of Munaily-Mola deposit using organic solvent of petroleum ether.
