Energy Science &Engineering, Volume 14, Issue 3, Page 1626-1662, March 2026.This review systematically explores the molecular behavior of diverse surfactants (anionic, cationic, nonionic, amphoteric) at the oil–water interface through molecular dynamics simulations. It highlights their roles in reducing interfacial tension, altering interfacial structure, and enhancing oil recovery efficiency.

Effect of Asphaltenes and Asphaltene Dispersants on Wax Precipitation and Treatment
Colloids and InterfacesA detailed understanding of the interactions between wax and asphaltenes with other components of crude oils and the effect of treatments with paraffin inhibitors (PIs) and asphaltene dispersants (ADs), with a focus on identifying specific structure ...

Influence of polar solvents on the straight distillation of crude oil [PDF]
, 2013 It is offered to use for activation of oil raw materials of an additive of polar organic solvents. It is shown that for a preliminary estimate of activating action of additives it is possible to use results of the comparative analysis of properties of ...

Processibility of black garbage bag as a novel binder system in metal injection molding [PDF]
, 2012 The issues to be highlighted here is to fundamentally evaluate the potential of using waste Garbage Bag from High Density Polyethylene (HDPE) as a backbone binder in Metal Injection Molding (MIM.) This is by the fact that the earth has tons of ...

Aspects of asphaltene aggregation obtained from coarse-grained molecular modeling
, 2015 We have performed a molecular-simulation-based study to explore some of the underlying mechanisms of asphaltene aggregation. The daunting complexity of the crude oil + asphaltene system precludes any type of meaningful molecular simulation unless some ...

Waxes in asphaltenes of crude oils and wax deposits
Petroleum Science, 2016 Composition and molecular mass distribution of n-alkanes in asphaltenes of crude oils of different ages and in wax deposits formed in the borehole equipment were studied. In asphaltenes, n-alkanes from C12 to C60 were detected.
