“…of membrane contactors using ILs as adsorbents [125]. The separation of gases using ILs is achieved primarily due to the difference in their solubility [126][127][128]. CO 2 capture can be carried out by its absorption with ILs, their solutions, or a porous material with ILs [129].…”

The deteriorating environmental situation has stimulated the world community to develop research related to the decarbonization of the economy and hydrogen energy. These two areas are essentially focused on membrane technologies, which play a crucial role in solving key tasks for these areas. This review is devoted to this research. The first part describes various membrane technologies aimed at capturing CO 2 from the most common gas mixtures, primarily containing nitrogen, methane, and hydrogen. In recent years, studies related to the amine purification of CO 2 , including membrane technologies, and the use of porous membranes filled with ionic liquids has also been intensively developed. Electromembrane technologies are also being developed that allow not only capture of CO 2 but also to process it into fuel or valuable chemicals. The course taken by several developed countries, including Russia, for the development of hydrogen energy includes the production, purification of hydrogen, and its conversion into energy. It should be noted that membrane technologies are fundamentally important for the development of each of these areas. Thus, the evolution of hydrogen is possible with the use of polymer membranes, and for deep purification and production of high-purity hydrogen by membrane catalysis; membranes based on palladium alloys are used. Finally, fuel cells are developed to produce energy from hydrogen, the most important part of which are proton or oxygen-conducting membranes.

“…Carbon capture technologies are attracting the attention of governments and scientists due to the significant contribution of carbon dioxide (CO2) to greenhouse gases [1]. This high CO2 concentration makes it a leading cause of climatic disturbances, including notable ones as high earth surface temperature and global warming [2]. Among different technologies, carbon capture based on liquid absorbents like aqueous alkanolamines has high CO2 removal efficiency (> 80%) even at low pressures and CO2 concentrations [3] and is relatively inexpensive [4,5].…”

“…The world of ionic liquids (ILs) is continuously changing, and currently they are entering an era of industrial applications. Commercialization of the process of removal of basil, difasol, and, recently, mercury from the natural gas is among the most promising industrial method developed using ILs. , ILs possess some remarkable and even tunable physical–chemical properties, making them potentially excellent solvents for numerous applications, including heavy metal removal, CO 2 capture, oil spill remediation, heat-transfer fluid for solar applications, and so forth. − The extraction of naphthenic acid (NA) from crude oil and model oil has also been performed via ILs using the neutralization, liquid–liquid extraction (LLE), and adsorption approach. , NA is one of the critical reasons for corrosion in crude oil refineries utilizing a high acidic oil, and it also causes foaming in the desalter. Conversely, NA is a valuable byproduct with good market value and has many applications in various industries, making it highly desirable to be extracted from oil for valorization purposes …”

Ionic liquids (ILs) show remarkable performance in enhancing the naphthenic acid extraction efficiency and decreasing the extraction time. However, the ultrasonic-assisted IL-based extraction of naphthenic acid is merely addressed previously. Therefore, this study investigated the impact of essential ultrasonic parameters, including amplitude and time, on naphthenic acid extraction using different ILs, and the system was optimized for maximum extraction. The IL 1,8-diazobicyclo[5.4.0]-undec-7-ene (DBU) with thiocyanate anions revealed the highest efficiency in extracting naphthenic acid from a model oil (dodecane) at optimized conditions, and the experimental liquid–liquid equilibrium data were obtained at atmospheric pressure for the mixture of dodecane, [DBU], thiocyanate, and naphthenic acid. In addition, the influence of the chain length of the cation (hexyl, octyl, or decyl) on the extraction efficiency was also evaluated by determining the distribution coefficients, and the conductor-like screening model for real solvents (COSMO-RS) study was carried out at infinite dilution. It was found that [DBU-Dec] [SCN] gives the best extraction efficiency and has a distribution coefficient of 9.2707 and a performance index of 49.48. Based on these values, ILs can be ordered as follows: [DBU-Dec] [SCN] > [DBU-Oct][SCN] > [DBU-Hex][SCN] in the decreasing order of performance index 49.48, 41.58, and 28.13. Moreover, non-random two liquid and Margules thermodynamic models were employed to investigate the interaction parameters between the components. Both models showed excellent agreement with the experimental results and could successfully be used for ultrasonic-assisted IL extraction of naphthenic acid.
