“…62 Moreover, the addition of polymers and surfactants during the oil recovery process intensifies the degree of oil−water emulsification and improves the stability of the oil−water interface. 11 Currently, the methods to demulsify oil−water emulsions and induce liquid−liquid separation include a demulsified method, 63 membrane separation method, 64 centrifugation method, 65 external electric field method, 66 ultrasonic method, 67 and magnetic demulsification. 68…”

“…On the one hand, the geometry of the hydrocyclone is related to the centrifugal force formed by the flow of the oil−water emulsion; on the other hand, the operating parameters of hydrocyclone centrifugal separation (e.g., flow rate and pressure drop) are also important for the centrifugal force and separation efficiency. 65 Furthermore, the properties of the emulsion also affect the cyclonic flow rate and centrifugal force strength, such as oil concentration, 116 oil− water density difference, 65 viscosity, 117 and oil droplet particle 120 established a mathematical model of the cyclonic flow field within a hydrocyclone, but the aggregation behavior occurring at the interface during droplet collision was not considered; therefore, further studies are still needed.…”

“…Zhou et al conducted Computational Fluid Dynamics simulations for disk centrifuges using the population balance model model and clarified the disruption of the oil–water interface and the aggregation process of emulsion droplets in disk centrifuges; the degree of aggregation of emulsion droplets increases with an increase in the number on disk layers. On the one hand, the geometry of the hydrocyclone is related to the centrifugal force formed by the flow of the oil–water emulsion; on the other hand, the operating parameters of hydrocyclone centrifugal separation (e.g., flow rate and pressure drop) are also important for the centrifugal force and separation efficiency . Furthermore, the properties of the emulsion also affect the cyclonic flow rate and centrifugal force strength, such as oil concentration, oil–water density difference, viscosity, and oil droplet particle size, decreasing in the efficiency of oil–water interface disruption.…”

As the global oil market continues to tighten, there is an increasing focus on enhancing oil recovery. However, enhanced oil recovery technologies require the addition of chemical components such as surfactants, alkalis, and polymers to the oil reservoir. These chemical components change the interface structure and affect fluid flow characteristics and phase interactions through adsorption and other behaviors, thus affecting the production efficiency and energy consumption of oil recovery, gathering, processing, and transportation. Particularly, a stable interface is formed during oil recovery that can sharply increase the difficulty of phase separation during oil gathering and processing, thereby considerably decreasing the separation efficiency. Therefore, it is crucial to understand the effect of the interface structure and behavior on fluid flow characteristics and phase interactions for the advancement of the petroleum industry. Herein, the application and regulation of interfaces in the petroleum industry for fluid flow characteristics and phase interactions are reviewed, approaches for characterizing interface characteristics are critically analyzed and discussed, mechanisms of various factors influencing interface formation and stability through phase interactions are investigated, and methods of interface inhibition and destruction are summarized. Moreover, the latest techniques for applied interface formation in the petroleum industry are discussed, and the challenges and research prospects related to interfaces are summarized, providing references for enriching theoretical research in the field of interfaces within the petroleum industry and efficiently optimizing the production and operation of the petroleum industry.

“…One part of the energy is used to meet the internal heating demand of the sewage treatment plant, and the other part is used to transfer the heat energy to the heat station for urban building heating [113]. The use of sewage-source heat pump technology to extract heat energy from sewage has great potential for energy savings, and the extracted heat can be used for internal use in sewage treatment plants and building heating around sewage treatment plants [114]. It not only saves heat for the operation of the sewage treatment plant, but also facilitates the “carbon neutralization” operation mode of the sewage treatment plant.…”

Wastewater treatment can consume a large amount of energy to meet discharge standards. However, wastewater also contains resources which could be recovered for secondary uses under proper treatment. Hence, the goal of this paper is to review the available green energy and biomass energy that can be utilized in wastewater treatment plants. Comprehensive elucidation of energy-efficient technologies for wastewater treatment plants are revealed. For these energy-efficient technologies, this review provides an introduction and current application status of these technologies as well as key performance indicators for the integration of green energy and energy-efficient technologies. There are several assessment perspectives summarized in the evaluation of the integration of green energy and energy-efficient technologies in wastewater treatment plants. To overcome the challenges in wastewater treatment plants, the Internet of Things (IoT) and green chemistry technologies for the water and energy nexus are proposed. The findings of this review are highly beneficial for the development of green energy and energy-efficient wastewater treatment plants. Future research should investigate the integration of green infrastructure and ecologically advanced treatment technologies to explore the potential benefits and advantages.

The demand for district heating and cooling systems in block units with a heat pump that utilizes various unused energy sources for energy supply has been increasing. This study investigated experimentally the ground source heat pump (GSHP) and sewage water source heat pump (SWSHP) facilities used in block cooling and heating networks. Then, a heat pump performance prediction model was derived for utilization in future designs. Operational data for heating and cooling energy supply from an experimental site were investigated for the period between 2018 and 2020. During the cooling season, the coefficient of performance (COP) of the GSHP was approximately 4.1, and that of the SWSHP was approximately 2.9. The cooling performance of the SWSHP gradually decreased because of the fouling. The COP of the GSHP and SWSHP during the heating season was approximately 3.6 and 3.4, respectively. The results also demonstrated that, if fouling in the SWSHP can be prevented or reduced, the acquired COP can be similar to that of the GSHP. The derived prediction model serves as a good reference for engineers who require information on the performance of field operations.
