“…Besides, carrying out a surfactant flooding test in porous media is an another effective method for determining whether emulsification can easily occur, while its repeatability and operation time are difficult to control. In addition, ultrasonic vibration is another useful method for characterizing the emulsification process under a controlled condition. − However, a major drawback of this approach is that the size of emulsions prepared by ultrasonic vibration is extremely small, thereby making it impossible to further study emulsion stability, which is an another important parameter in the process. In recent years, microfluidic models are commonly employed to mobilize the generation of emulsion droplets in real time. − However, this method is also limited by the channel size of etching model, which is insufficient for the quantitative characterization of emulsifying capability and emulsifying stability of complex oil–water systems.…”

The evaluation of the ease to generate emulsions and emulsions stability of oil−water system is essential for the investigation and application of chemical flooding technology for the enhanced oil recovery (EOR). However, the previous characterization methods have mainly focused on emulsion stability. To fill this gap, this study designed a novel instrument for visualizing the presence of emulsions and the separation of an oil−water system. Thereafter it also proposed quantitative methods: the emulsification index (EI) for characterizing the ease of surfactants to generate emulsions with crude oil and the demulsification index (DI) for describing emulsion stability. The results show that EI and DI can accurately characterize the dynamic characteristics of emulsions generation and demulsification, respectively. On the basis of the numerous test data composed by three crude oils and seven surfactants with different concentrations, the emulsifying capability and emulsion stability of different oil−water samples can be quantitatively determined. More importantly, these differences between various oil−water samples caused by surfactant concentration, surfactant types and crude oil property can also be accurately distinguished. Besides, the core flooding tests also provide support for the EI and DI and are reasonable parameters for characterization of the emulsification capability and emulsion stability of oil−water systems. Therefore, the overall investigations ultimately revealed that the parameters EI and DI can be used to determine ease of emulsion generation and separation of oil−water systems with an acceptable level of accuracy. The findings of this study provide a novel method for preparing effective chemical agents, which is useful for EOR fields with economic returns.

Magnetic hyperthermia (MH) is the phenomenon of increasing the temperature of a system with magnetic nanoparticles (NPs) subjected to an alternating magnetic field (AMF). This phenomenon occurs as the energy from the magnetic field is transformed into heat by mechanical (Brownian relaxation) and/or magnetic (Neél relaxation) magnetization reversal. In this work, we developed an experimental setup to test the use of MH for industrial applications. The liquid's viscosity decreases as the temperature increases, and liquids with high viscosity are present in several industries (e.g., O&G, pharmaceutical, chemical, and food), where a reduction in viscosity can translate into lower costs and greater profitability, for instance, in some industries, by decreasing the pressure drop and hence increasing the flow rate and in others by avoiding problems that occur at low temperature. Our pilot apparatus was built to investigate the hyperthermia effect when a mixture of viscous liquids and NPs, with an average size of 8 nm (transmission electron microscopy), flows through an AMF. In this study, three different configurations were tested, two static, with mixture samples of 1 and 100 mL, and one under dynamic flowing conditions. Two important results should be highlighted: (1) static experiments with 1 and 100 mL had similar SAR [W/g] values, demonstrating the viability of scaling up and (2) there was an increase in the temperature of the colloid flowing through the AMF. It was therefore possible to observe a clear increase in the liquid's temperature when subjected to an AMF, for all condition cases. The results suggest that this technology can be applied on an industrial scale by optimizing the coils and NP properties.
