Summary: The Second Oil Production Plant of Xinjiang Oilfield faces challenges in separating a large amount of highly emulsified crude oil, which consists of conventional water flooding, chemical flooding, and fracturing backflow fluid. Factors such as high zeta potential, low density difference, high viscosity, and small emulsion particles contribute to the difficulty in demulsification. Through systematic experiments, optimal demulsification approaches were identified, including raising the temperature and demulsifier concentration for water flooding emulsion, adjusting the pH value and adding demulsifier for chemical flooding emulsion, and no extra treatments for fracturing backflow fluid emulsion. This study provides new insights for emulsion treatment in later stages of oilfield development.

Summary: An amphiphilic and magnetically recyclable graphene oxide demulsifier was synthesized by grafting magnetic nanoparticles and ethylenediamine onto the GO surface, exhibiting favorable demulsification performance for crude oil-in-water emulsions under various pH conditions. The MR-GO can be reused multiple times with consistent high demulsification efficiency. Through a combination of interfacial adsorption interactions, electrostatic attraction, and external mechanical forces, the demulsifier disrupts and stabilizes the emulsion interface, facilitating the rapid gathering of oil droplets to accomplish demulsification.

Summary: In this study, carboxymethyl cellulose (Walocel) and methyl cellulose-E5 were found to be more effective for deionized water-in-crude oil demulsification. The presence of ions slowed down the demulsification of Methocel-E5 more than that of Walocel, likely due to the different hydrogen bond strength and van der Waals interactions with water molecules. The polar 2-hydroxypropyl substitutes in Methocel E5 resulted in much less effective saline demulsification compared to Walocel.

Summary: In this study, the relationship between crude oil properties and emulsion stability was investigated using the XDLVO theory. The results indicate that total base number (TBN) and polarity of the crude oil medium can reliably predict emulsion stability. Sensitivity analysis showed that electron acceptor/donor components play an important role in short distances between droplets. Adhesion tests revealed that the presence of HCl solution increases the adhesion of crude oils to glass surfaces.

Summary: The production of microbial biomass, microbial cell properties, and biological function are significantly influenced by different hydrophobic organic compounds (HOCs). This study investigated the metabolic responses in Dietzia natronolimnaea S-XJ-1, a biodemulsifier, when utilizing alkanes and fatty acid esters as HOCs. The transcriptomic analyses revealed the upregulation of ATP-binding cassette transporters and the downregulation of transporters for hydrophilic nutrients and cell division genes, which may explain the lower biomass production in liquid paraffin-cultured S-XJ-1. In addition, the upregulation of genes involved in surface protein biosynthesis, poly-L-glutamine layer, and mycolic acids enhanced the cell-surface hydrophobicity and biodemulsifying activity of liquid paraffin-cultured S-XJ-1. These findings can contribute to the design of more effective biodemulsifiers and deepen our understanding of complex metabolic responses induced by different HOCs.

Summary: This study proposes a new approach to explore the water-energy-carbon (WEC) nexus of wastewater treatment plants (WWTPs) using a Water-Energy-Carbon Coupling Index (WECCI) and a four-quadrant clustering (FQC) method. The analysis of operational data from a WWTP in southern China reveals that the WECCI increased after the first standard upgrade and decreased after the second standard upgrade, indicating unexpected changes in overall performance. The FQC method shows that a majority of the operation data are concentrated in the WEC best synergy zone after the first standard upgrade, while a significant percentage are concentrated in the low carbon trade-off zone after the second standard upgrade. These findings highlight the importance of WECCI and FQC as tools for quantitatively assessing the integrated performance of WWTPs and understanding the complex WEC mechanisms, facilitating the transition of WWTPs towards carbon neutrality.

Summary: This review discusses the adsorption characteristics of carbocatalysts to persulfate (PS) and organics, and the influences of carbon adsorptive properties on PS activation pathways. The cycle of adsorption and oxidation on carbocatalysts increases the reaction stoichiometric efficiency (RSE) and kinetic rate (kobs) of PS-AOPs. The surface and structure characteristics of carbocatalysts are investigated, which are responsible for the behaviors of adsorption and activation. Optimization strategies of carbocatalysts are proposed to decrease the inhibition of co-existing organics and external substances in actual wastewater.

Summary: The present study investigates the nonlinear random vibration of deep-water piers under horizontal seismic excitation. The stochastic dynamic model of the pier is formulated, and the equations for the amplitude envelope and the conditional reliability function are derived. Numerical discussions are conducted to analyze the effects of various factors on the system response and first-passage failure. The results show that increased excitation intensity, mass ratio, immersion ratio, and hydrodynamic effect amplify the response and reduce the reliability of the deep-water pier system. The findings of this study provide valuable insights for the optimal seismic design of deep-water piers.
