“…The mechanism of spontaneous emulsification of immiscible liquids is determined by the physiochemical properties of the solute, solvent, additives, and system condition. In some conditions, such as the emulsifying hexadecane in Triton X-100 solution, diffusing the surfactant molecules, which is an amphiphilic molecule consisting of the hydrophobic and hydrophilic part shown in Figures and , through the intermediate layer is considered a control step of the process …”

This study quantifies the influence of electrolytes on the kinetics of the spontaneous emulsification phenomenon (SEP) of heavy hydrocarbons in a nonionic surfactant solution. The rate of emulsifying hexadecane in Triton X-100, with the presence of sodium chloride and potassium chloride, has been measured using a technique of monitoring single oil droplet photography. The emulsion droplet size produced in the process was measured under the same conditions by using dynamic light scattering. The data obtained from the two experiments were employed to investigate the mass transfer coefficient of the surfactant molecules through the intermediate layer formed between hexadecane and the surfactant solution. It was found that the electrolytes in an aqueous solution increase the surfactant diffusion rate through the intermediate layer and reduce the emulsion droplet size. As a result, both electrolytes reduce the rate of spontaneous emulsification, with potassium chloride having a more substantial reduction. A model was developed to quantify the influence of electrolytes on the kinetics of the SEP. The data and modeling results verify the influence of ions on the kinetics of spontaneous emulsification. The results provide a significant foundation for predicting the solubilization of heavy hydrocarbons in an electrolyte solution.

“…Ma et al 58 studied the self-assembly of polyoxyethylated alcohols in emulsion systems through multi-scale molecular dynamics simulation, and they found that the molecular structure of surfactants greatly affected the interfacial properties and the emulsion/microemulsion formation. Zabar et al 59 reaction occurs at the oil−water interface. The overall emulsification process consists of the following elementary processes: emulsion formation on the oil surface by surfactants, movement of the emulsion away from the oil surface, and diffusion of the surfactant through the emulsified layer, as shown in Figure 5.…”

In the chemical enhanced oil recovery (CEOR) process, the in situ emulsification between the oil displacement agent and crude oil plays an important role in the swept volume enlargement and displacement efficiency improvement. However, as a result of the complex geologic structure of the reservoir and varied remaining oil types, the occurrence of in situ emulsification in the reservoir and its role in enhancing oil recovery (EOR) are still unclear. We summarized and discussed the current understanding and existed problems in the in situ emulsion formation mechanism, its characterization method, and EOR capacity based on the current research results. The field application results were collected to clarify its potential in EOR. It was found that the in situ emulsification had been verified as an important role in oil recovery in both laboratory and pilot tests. However, the preparation and evaluation methods of in situ emulsification exist as a big difference with real conditions, which may cause people to misunderstand its EOR mechanism. The requirement for the in situ emulsification is quite different between the high-and low-permeability reservoirs. We expected that this review and perspective could help people understand the problems in this area. The proposed solution method could also draw some attention, which will promote the application of the in situ emulsification technique.

The interplay of interfacial tensions on droplets results in a range of self‐powered motions that mimic those of living systems and serve as a tunable model to understand their complex non‐equilibrium behavior. Spontaneous shape deformations and oscillations are crucial features observed in nature but difficult to incorporate in synthetic artificial systems. Here, we report sessile oil‐in‐water emulsions that exhibit rapid oscillating behavior. The oscillations depend on the nature and concentration of the surfactant, the chemical composition of the oil, and the wettability of the solid substrate. The rapid changes in the contact angle per oscillation are observed using side‐view optical microscopy. We propose that the changes in the interfacial tension of the oil droplets is due to the partitioning of the surfactant into the oil phase and the movement of self‐emulsified oil out of the parent droplets giving rise to the rhythmic variation in droplet contact‐line. The ability to control and understand droplet oscillation can help model similar oscillations in out‐of‐equilibrium systems in nature and reproduce biomimetic behavior in artificial systems for various applications, such as microfluidic lab‐on‐a‐chip and adaptive materials.
