“…(2) gas-liquid under low-pressure conditions (Thrän et al 2014). In the gas-gas module, both sides have a gaseous state, whereas in the latter module, the gaseous CO 2 and H 2 S atoms diffuse into the fluid state on the opposite side of the membrane (Kim et al 2021). Usually, in a gas-gas module, raw biogas is compressed with 20-40 bar pressure which results in accumulation of retentate at the inlet rich in biomethane at atmospheric pressure; over 97% pure biomethane can be produced through decompression to negative pressure levels by partially recycling the permeate saturated with CO 2 and residual CH 4 (Bauer et al 2013b).…”

Biogas production is rising in the context of fossil fuel decline and the future circular economy, yet raw biogas requires puri-fication steps before use. Here, we review biogas upgrading using physical, chemical and biological methods such as water scrubbing, physical absorption, pressure swing adsorption, cryogenic separation, membrane separation, chemical scrubbing, chemoautotrophic methods, photosynthetic upgrading and desorption. We also discuss their techno-economic feasibility. We found that physical and chemical upgrading technologies are near-optimal, but still require high energy and resources. Biological methods are less explored despite their promising potential. High-pressure water scrubbing is more economic for small-sized plants, whereas potassium carbonate scrubbing provides the maximum net value for largesized plants.

“…Moreover, the organization of the absorption/desorption process in membrane contactors makes it possible to independently control the flows of gas and liquid (since the membrane acts not only as a developed surface but also as a phase boundary). Another indisputable advantage of organizing the process in a membrane contactor is the ability to conduct desorption at temperatures below the boiling point of the absorbent, which leads to a decrease in energy consumption and significantly reduces the degradation of alkanolamines [109,110]. Desorption at a lower temperature reduces energy requirements by minimizing amine and water evaporation.…”

“…Since in the membrane contactor there is practically no drop entrainment of the absorbent (mainly in the case of a non-porous selective layer), it becomes possible to use a wide range of absorbents, including those based on ionic liquids and physical sorbents [84,110,[113][114][115]. Direct contact between the membrane and the absorbent introduces a requirement for the chemical and thermal stability of the membrane.…”

“…Direct contact between the membrane and the absorbent introduces a requirement for the chemical and thermal stability of the membrane. In this regard, systems based on perfluorinated polymers and polypropylene are widely used [110]. When operating in the membrane contactor mode, the authors [114] considered a porous membrane made of polytetrafluoroethylene (PTFE) and a composite membrane of Teflon and polypropylene (PP) with 1-butyl-3methylimidazolium tricyanomethanide as an absorption ionic liquid, which showed comparable separation characteristics.…”

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.

“…Membrane contactors have received considerable attention in various applications such as membrane distillation (MD) for desalination [ 1 , 2 ], membrane absorption (MA) [ 3 ], and membrane stripping (MS) [ 4 ] for CO 2 capture, due to their high mass transfer area and flexible installation and operation. Four configurations of MD processes have been extensively investigated for separation, including direct contact membrane distillation (DCMD), air gap membrane distillation (AGMD), sweep gas membrane distillation (SGMD), and vacuum membrane distillation (VMD).…”

Ceramic membranes have the advantages of high mechanical strength and thermal stability and are promising candidates for membrane distillation. Ceramic membranes are generally designed to have a multilayer structure with different pore sizes to create a high liquid entry pressure and obtain a high permeability. However, these structural characteristics pose significant difficulties in predicting permeate flux in a ceramic membrane contactor for vacuum membrane distillation (VMD). Here, a modeling approach was developed to simulate the VMD process and verified by comparing the simulated results with the experimental data. Furthermore, correlations are proposed to simplify the calculations of permeate flux for VMD using asymmetric ceramic membranes by assuming those multilayers to be an effectively quasi-symmetric layer and by introducing a correction factor. The simulation results indicated that this simplified correlation was effective and enabled a quick estimation of the effect of membrane parameters on permeate flux.
