“…The permeance of the membrane increased from 110 GPU to 130 GPU while simultaneously increasing the CO 2 /CH 4 selectivity from 25 to 45. CNTs have been also employed in order to exploit the enhanced swelling properties in membrane containing CO 2 -philic enzymes [ 79 ]. Zhao et al [ 80 ] and Ansaloni et al [ 81 ] introduced MWCNTs and amine functionalized MWCNTs in facilitated transport membranes in order to improve the mechanical stability of the selective layer under high-pressure and high-temperature conditions.…”

Membrane technology has the potential to be an eco-friendly and energy-saving solution for the separation of CO2 from different gaseous streams due to the lower cost and the superior manufacturing features. However, the performances of membranes made of conventional polymers are limited by the trade-off between the permeability and selectivity. Improving the membrane performance through the addition of nanofillers within the polymer matrix offers a promising strategy to achieve superior separation performance. This review aims at providing a complete overview of the recent advances in nanocomposite membranes for enhanced CO2 separation. Nanofillers of various dimensions and properties are categorized and effects of nature and morphology of the 0D to 2D nanofillers in the corresponding nanocomposite membranes of different polymeric matrixes are discussed with regard to the CO2 permeation properties. Moreover, a comprehensive summary of the performance data of various nanocomposite membranes is presented. Finally, the advantages and challenges of various nanocomposite membranes are discussed and the future research and development opportunities are proposed.

“…However, the dispersion of nanoparticles in polymeric solutions is limited to lower concentrations. Saeed et al , studied CNT‐promoted MMMs for CO 2 capture. The CNT loading reported in this work was limited to 1.5 % with respect to the polymer due to aggregation of nanoparticles at higher loading.…”

CO2 emission from anthropogenic sources has raised worldwide environmental concerns and hence proficient energy paradigm has tilted towards CO2 capture. Membrane technology is one of the efficient technologies for CO2 separation since it is environmentally friendly, inexpensive, and offers high surface areas. Various approaches are discussed to improve membrane performance focusing mainly on permeability and selectivity parameters. Different types of fillers are incorporated to reach the Robeson's upper bound curve. In this review, polymer‐inorganic nanocomposite membranes for the separation of CO2, CH4, and N2 from various gas mixtures are comprehensively discussed. Metal organic frameworks (MOFs) and ionic liquid (ILs) mixed‐matrix membranes are also considered.

“…In the circumstance of a large size membrane module, the effects of other factors associated to feed gas composition could be remarkable. As indicated by experimental studies, water vapor in the gas stream can benefit the facilitated transport of CO 2 in AFTMs 22–25 . For a large size membrane system, when a feed gas stream passes through a large membrane module, water vapor content in the gas stream declines along with the streamflow in the module.…”

“…As indicated by experimental studies, water vapor in the gas stream can benefit the facilitated transport of CO 2 in AFTMs. [22][23][24][25] For a large size membrane system, when a feed gas stream passes through a large membrane module, water vapor content in the gas stream declines along with the streamflow in the module. This happens as a direct consequence of water permeation, resulting in reduced separation performance of AFTMs along with the module.…”

Water vapor effects on CO₂ separation of amine‐containing facilitated transport membranes (AFTMs) module: mathematical modeling using tanks‐in‐series approach

Amine-containing facilitated transport membranes (AFTMs) are emerging membranes and have great potential for CO 2 capture. AFTMs are particularly suitable for humid flue gases, as water vapor enhances the facilitated transportation of CO 2. However, there is a lack of mathematical models available to evaluate the impact of water vapor on CO 2 separation performance for large-scale membrane modules. Therefore, developing a mathematical model considering the water vapor effects is of great importance to guide the large-scale applications of AFTMs for CO 2 capture. In this study, a mathematical model using tanks-in-series approach for CO 2 capture through AFTMs is proposed. In this model, the tanks-in-series approach can reflect the variable (water vapor-dependent) gas permeance along the membrane module. Modeling results showed the necessity of considering the effect of water vapor content decline along the module. In addition, both increasing temperature and pressure primarily lead to a faster decline of relative humidity (RH) along the membrane module, resulting in an increase of CO 2 recovery but a decrease of CO 2 product purity. For a gas stream with relatively low water vapor content (<2% in this study), different H 2 O permeance has a minor effect on separation performance. Moreover, permeate gas with higher water vapor content as well as higher RH is considered more suitable for further treatment of second stage membrane separation. In conclusion,
