“…Perkin Elmer Spectrum One FTIR spectrometer equipped with Spectra One software for analysis was used to observe the FTIR spectra in the wavelength range 400–4,000 cm −1 . Membrane samples were placed in a sample cell, and the spectrum was acquired by the co‐addition of 20 scans at a resolution of 4 cm −1 under transmittance mode .…”

This article presents fabrication, characterization, and performance evaluation of polyetherimide (PEI)/polyvinyl acetate (PVAc) blend membranes. Polymer blend membranes with various blend ratios of PEI/PVAc were prepared by solution casting and evaporation technique. Morphology and miscibility of polymer blend membranes were characterized by field emission scanning electron microscope (FESEM) and differential scanning calorimetry (DSC), respectively. The interaction between blend polymers was analyzed by FTIR analysis. Gas separation performance was evaluated in terms of permeability and selectivity. FESEM results revealed that pure polymer and blend membranes were homogeneous and dense in structure. A single glass transition temperature of polymer blend membranes was found in DSC analysis which indicated the miscibility of PEI/PVAc blend. FTIR analysis confirmed the presence of molecular interaction between blend polymers. The permeation results showed that the presence of PVAc (3 wt%) in blend membranes has improved CO2 permeability up to 95% compared to pure PEI membrane. In addition, CO2/CH4 selectivity was found to be 40% higher than pure PEI membrane. This study shows that blending a small fraction of PVAc can improve the gas separation performance of PEI/PVAc blend membranes. POLYM. ENG.

“…A large number of studies have been made to study the applications of the ILPM in the gas separation process. Mannan, et al [ 89 ] prepared ionic liquid polymeric membranes (ILPMs) at high concentrations of ionic liquid that combined polyethersulfone (PES) polymer with 1-ethyl-3-methyl imidazolium bis(trifluoromethylsulfonyl)imide ([EMIM][Tf 2 N]). The ionic liquid used in their study was (1-ethyl-3-methyl imidazolium bis(trifluoromethylsulfonyl) imide ([EMIM][Tf 2 N])) which has a high affinity for CO 2 gas.…”

Heightened levels of carbon dioxide (CO2) and other greenhouse gases (GHGs) have prompted research into techniques for their capture and separation, including membrane separation, chemical looping, and cryogenic distillation. Ionic liquids, due to their negligible vapour pressure, thermal stability, and broad electrochemical stability have expanded their application in gas separations. This work provides an overview of the recent developments and applications of ionic liquid membranes (ILMs) for gas separation by focusing on the separation of carbon dioxide (CO2), methane (CH4), nitrogen (N2), hydrogen (H2), or mixtures of these gases from various gas streams. The three general types of ILMs, such as supported ionic liquid membranes (SILMs), ionic liquid polymeric membranes (ILPMs), and ionic liquid mixed-matrix membranes (ILMMMs) for the separation of various mixed gas systems, are discussed in detail. Furthermore, issues, challenges, computational studies and future perspectives for ILMs are also considered. The results of the analysis show that SILMs, ILPMs, and the ILMMs are very promising membranes that have great potential in gas separation processes. They offer a wide range of permeabilities and selectivities for CO2, CH4, N2, H2 or mixtures of these gases. In addition, a comparison was made based on the selectivity and permeability of SILMs, ILPMs, and ILMMMs for CO2/CH4 separation based on a Robeson’s upper bound curves.

“…Flux and permeability were calculated by using Eqn (2). The gas flux ( J ) through the membrane was defined by the following expression (Eqn ):

J = \frac{Δ V}{A t}

where ΔV is the volume of the permeated gas, cm 3 ; A is the membrane area, cm 2 ; and t is the time, s. The permeance ( π ) through the membrane and the relation to the permeability ( P ) were defined by Eqns and :

π = \frac{J}{Δ p}

π = \frac{P}{L}

where Δp is the partial pressure difference between the upstream and downstream side of the membrane and L is the membrane thickness…”

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.
