“…129 Existing studies suggest that an important parameter for ultrasonic defoaming is the ultrasonic treatment temperature; an increase in temperature increases the viscosity of the foam system. 86 Pal et al 130 considered the effect of surfactant type and concentration in a foam system on ultrasonic defoaming efficiency and reported that ultrasonic defoaming is effective but has different effects in the presence of different surfactants, the higher the concentration the longer the defoaming time, and the defoaming rate increases with an increase in temperature; at a constant temperature, foam formation and defoaming obeyed the exponential function. Additionally, Wang et al 19 studied the decay kinetic characteristics of ASP-strengthened foams using ultrasonic standing waves, based on which an energy-dependent kinetic model for the decay of the gas−liquid interface of foams was proposed, the potential collapse mechanism of the gas−liquid interface is revealed, which fills the knowledge gap in the ultrasonic defoaming theory.…”

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.

“…[52][53][54] Coincidently, those aforementioned physicochemical properties facilitating the cleaning efficiency, such as low surface tension, strong aggregation ability and fast adsorption kinetics, often result in the strong foamability and foam stability in surfactant solution. [55][56][57][58] Therefore, the development of surfactant systems with high cleaning efficiency but adjustable foaming ability in different conditions encounters great technological hurdles although it is urgently desired in multiple fields.…”

“…15 Chemical defoaming additives have been used since the early 20th century as a means of removing foams. 16 These additives, namely, defoamers or antifoams, are added to reduce or eliminate these foams. Often, these two terms are used interchangeably.…”

Antifoam plays an essential role in maintaining the continuous removal of acid gases by the absorption process. However, a holistic review of the fundamentals and desirable selection criteria for different types of antifoams for the gas sweetening process is scarcely available. Therefore, this review analyses the selection criteria of each type of antifoam for acid gas sweetening, particularly silicone, polyether glycol, alcohol, and blended-based antifoams. These selection criteria are crucial in defining the properties and antifoaming performance in terms of solubility, dispersibility, surface tension, viscosity, defoaming rate, thermal stability, stability of defoaming performance, potential hazard, and chemical inertness. Hence, this review provides valuable insight into the existing and potential antifoams that could be employed in the acid gas sweetening process along with their distinctive antifoaming ability, benefits, and drawbacks. From this review, blended antifoam is able to fulfill most of the selection criteria and will be further explored in a subsequent study.
