This research investigates the interactions between a novel environmentally friendly chemical fluid consisting of Xanthan gum and bio-based surfactants, and crude oil. The surfactants, derived from various leaves using the spray drying technique, were characterized using Fourier-transform infrared (FTIR) spectroscopy, zeta potential analysis, Dynamic light scattering, and evaluation of critical micelle concentration. Static emulsion tests were conducted to explore the emulsification between crude oil and the polymer-surfactant solution. Analysis of the bulk oil FTIR spectra revealed that saturated hydrocarbons and light aromatic hydrocarbons exhibited a higher tendency to adsorb onto the emulsion phase. Furthermore, the increased presence of polar hydrocarbons in emulsion phases generated by polar surfactants confirmed the activation of electrostatic forces in fluid–fluid interactions. Nuclear magnetic resonance spectroscopy showed that the xanthan solution without surfactants had a greater potential to adsorb asphaltenes with highly fused aromatic rings, while the presence of bio-based surfactants reduced the solution's ability to adsorb asphaltenes with larger cores. Microfluidic tests demonstrated that incorporating surfactants derived from Morus nigra and Aloevera leaves into the xanthan solution enhanced oil recovery. While injection of the xanthan solution resulted in a 49.8% recovery rate, the addition of Morus nigra and Aloevera leaf-derived surfactants to the xanthan solution increased oil recovery to 58.1% and 55.8%, respectively.

“…The hydrocarbons in the crude oil and ones adsorbed on the rock surface lies in a wide range of electric properties. According to the literature review, the dielectric constant of the asphaltenes could also be 3-4 times of the other hydrocarbons, such as alkanes [36][37][38][39][40]. Hence, the energy absorbed by asphaltene molecules could lie in the range of 3-4 times of the other hydrocarbons.…”

In this research, the effect of microwave radiation simultaneous with acidizing on the carbonate rock surface has been investigated. Saturated rock sections were first immersed in the acid solution, and then, exposed to the microwave at 1300 W and 780 W for 1, 2, and 3 min. The surface wettability and hydrocarbon desorption from the rock surface were respectively investigated by the contact angle measurement and Attenuated Total Reflectance-Fourier Transform Infra-Red (ATR-FTIR) spectroscopy. It was observed that the angle under the microwave in the vicinity of the acidic solution improves toward waterwetness and becomes oil-wet. The reduction of the contact angle in the combined mode is tenser due to the simultaneous effect of acid and microwave radiation. According to the ATR-FTIR spectrums, the microwave radiation of the sections during the acid treatment led to desorption of aromatic compounds, long alkanes, polar bonds (O-H and N-H), and the compounds with C=O functional groups. The electrically polar hydrocarbons have more

“…We need to develop new and efficient heat dissipation technologies to ensure the long-term reliable and safe operation of future wind turbines. [2] Early wind turbines, due to their small power and low heat generation, only required natural ventilation to achieve cooling requirements. As the power of wind turbines gradually increases, natural ventilation is no longer able to meet the cooling needs of the units.…”

The thermal management of wind turbines is an important guarantee for their long-term stable and reliable operation. This article combines a new type of pump driven two-phase flow cooling system with the heat dissipation system of wind turbines, compares wind turbines using two-phase flow cooling systems, studies their system performance during simulated operation in a certain wind turbine cabin, and conducts fitting research and performance analysis on their thermal characteristics. The results indicate that a water cooling system with a flow rate of 3L/min can provide heat dissipation that can be achieved using only a two-phase flow cooling system with a flow rate of 0.05L/min. In transitional seasons and winter conditions, utilizing pneumatic heat pipe technology and fluorine pump technology for refrigeration, fully utilizing natural cooling sources, the annual energy efficiency ratio (AEER) reaches 8-10, and the new heat dissipation technology can ensure the long-term reliable and safe operation of future wind turbines.
