“…There were three types of membrane contactors observed across the 525 studies: flat sheet (FS) (n = 79, 15%) [90,93,98,117,127,137,180,181,187,193,199,212,218,222,230,[238][239][240][243][244][245]248,249,256,267,268,278,282,284,287,289,302,305,[312][313][314][315]317,321,323,324,326,329,333,336,338,[343][344][345]347,352,356,…”

With fossil fuel being the major source of energy, CO2 emission levels need to be reduced to a minimal amount namely from anthropogenic sources. Energy consumption is expected to rise by 48% in the next 30 years, and global warming is becoming an alarming issue which needs to be addressed on a thorough technical basis. Nonetheless, exploring CO2 capture using membrane contactor technology has shown great potential to be applied and utilised by industry to deal with post- and pre-combustion of CO2. A systematic review of the literature has been conducted to analyse and assess CO2 removal using membrane contactors for capturing techniques in industrial processes. The review began with a total of 2650 papers, which were obtained from three major databases, and then were excluded down to a final number of 525 papers following a defined set of criteria. The results showed that the use of hollow fibre membranes have demonstrated popularity, as well as the use of amine solvents for CO2 removal. This current systematic review in CO2 removal and capture is an important milestone in the synthesis of up to date research with the potential to serve as a benchmark databank for further research in similar areas of work. This study provides the first systematic enquiry in the evidence to research further sustainable methods to capture and separate CO2.

“…Since GO sheets possess high aspect ratio, decrease in gas permeability is anticipated when added as a filler to a membrane. Although it is a logical trend for GO containing membranes, it is not the same for all kinds of membranes . Thus, each polymer/GO combination should be studied in detail in terms of gas separation behavior.…”

“…However PVDF was extensively investigated as membrane in other areas of membrane processes . Considering some published papers on GO containing MMMs, it can be concluded that GO with high aspect ratio is an inspiring filler for efficient MMM construction in practical gas separation application. PVDF was chemically modified using mixture of KOH and KMnO 4 according to the previous study .…”

In the present study, graphene oxide (GO) was incorporated into poly(vinylidene fluoride) (PVDF) and chemically modified PVDF (M-PVDF) to prepare mixed matrix membranes (MMMs) for gas separation application. Performed analyses proved appropriate dispersion of exfoliated GO sheets in polymer matrices and sufficient compatibility at the interfacial phases. M-PVDF based MMMs were thermally and mechanically more stable relative to the PVDF-based MMMs. The oxygen containing functional groups in M-PVDF was probably the main reason for this more stability. PVDF/GO MMMs rendered low gas permeability and high selectivity. Both impermeable GO sheets and crystalline phases of PVDF were responsible for such behavior. On the other hand, interestingly gas permeability of M-PVDF/GO MMMs was enhanced while no substantial decline was recorded in gas selectivity. For instance, He and CO 2 permeability was increased 12.46% and 25.89%, respectively, compared to the pure PVDF membrane. This behavior originated from functional groups of M-PVDF and the interaction of these groups with GO sheets. Since GO often amplified gas barrier properties of polymers, such increscent would be appreciable.

“…The technique above illustrated high applicability in terms of simulating further ranges and wider operational conditions and process parameters . However, few studies can be found applying artificial neural network modeling to assess membrane permeability, solubility, capacity, and selectivity prediction, and for simulation of CO 2 separation . Therefore, this approach can be a promising, fast, and precise alternative to other currently applied mathematical modeling techniques in the field of membrane performance evaluation and assessment.…”

High‐temperature CO₂ removal from CH₄ using silica membrane: experimental and neural network modeling

Inorganic membranes can operate under harsh conditions. However, successful synthesis of inorganic membranes is still challenging, and its performance depends on many factors. This work reports the effect of dip‐coating duration, inlet pressure, and inlet flow rate on the flux, permeability, and selectivity of silica membranes. A silica membrane was prepared by the deposition of silica sol onto porous alumina support. The permeability test was conducted at 100 °C using a single gas of CO2 and CH4. The highest flux was observed at the maximum inlet pressure and inlet flow rate for the membrane prepared at the minimum dip‐coating duration. The neural network modeling of the membrane predicted permeabilities showed a considerably high validity regression (R ≈ 0.99) of the predicted data linked to the experimental sets. The separation factor (α) was the highest at the maximum dip‐coating duration. The synthesized silica membrane has potential for CO2/CH4 separation under harsh operating conditions. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.
