Implication

Mechanistic model reveals dual-agent kinetic stabilization in petroleum water-in-oil emulsions, highlighting the need for tailored demulsification strategies.

Key Points

To determine the interfacial mechanisms and molecular species responsible for stabilizing water-in-oil emulsions within petroleum systems.
Developed a kinetic model evaluating the competitive adsorption of petroleum constituents at the oil-water interface.
Analyzed the interfacial dynamics between low-molecular-weight surfactant-like species and asphaltene subfractions.
Emulsion stabilization is governed by adsorption kinetics rather than differences in adsorption energies between competing chemical species.
Low-molecular-weight surfactants adsorb rapidly to reach thermodynamic equilibrium, whereas asphaltenic subfractions adsorb slowly and irreversibly to form rigid interfacial skins.
Effective emulsion breaking requires distinct demulsification strategies tailored specifically to the dominant stabilizing agent.
