“…5), but the SO2 permeability is almost two orders of magnitude higher in our PIM. The PIM-TMN-Trip membrane has a comparable selectivity as a recently reported water-swollen thin film membrane for separation of SO2 from similar flue gas mixtures, based on a Toray membrane, but the present PIM has a significantly higher permeability for SO2 than that reported in the literature [31]. Similarly to the present PIM, these water-swollen membranes and thermally rearranged membranes have also shown excellent performance for CO2/CH4 separation [30,[32][33][34].…”

Flue gas purification experiments were performed with a membrane made from the ultrapermeable polymer of intrinsic microporosity (PIM) based on tetramethyltetrahydronaphthalene unit coupled with bicyclic triptycene (PIM-TMN-Trip). Permeation experiments with a CO2-N2-O2-SO2 mixture, simulating flue gas from power plants, were performed by means of an in-house developed permeation unit. The results showed very high permeability of the membrane for sulfur dioxide SO2 and high permeability of CO2, lying mainly between the Robeson upper bound form 2008 and the recently reported upper bound from 2019. Moderately high mixed gas selectivity of SO2 and CO2 with respect to N2 (21-29 and 11-18, respectively), in combination with very high permeability (28•10 3 and 30•10 3 Barrer, respetively), suggest potential use for industrial gas separation processes. The SO2/CO2 mixed gas selectivity was relatively low (around 1.8), but comparable with other novel membranes, and both are removed simultaneously in the process of CO2 separation.

“…However, it can be difficult to apply polymer membranes when extracting natural gas on the coastline, since such gas contains a large amount of water. The presence of water vapor affects the mobility of Membranes 2023, 13, 805 2 of 14 polymer chains, transport channels, and interactions between natural gas and polymer functional groups [12][13][14].…”

The effect of water, methanol, and hexane vapors on gas permeability was studied in a hybrid membrane containing 5 wt% copolyimide brushes with poly(methyl methacrylate) side chains (PI-g-PMMA) in a poly(phenylene oxide) (PPO) matrix, and in a pristine PPO membrane. These membranes in the form of dense nonporous films were further examined by atomic force microscopy (AFM) and scanning electron microscopy (SEM), as well as by measuring their mechanical and gas transport properties. A gas separation study of the membranes in a dry state and the membranes saturated with water, methanol, and hexane vapors was performed to estimate the effect of each vapor on the H2, CO2, N2 permeability and selectivity in the separation of H2/N2 and CO2/N2 pairs. In general, saturation with water, methanol, and hexane vapors caused a decrease in the gas permeability of both membranes. The hybrid membrane containing copolyimide brushes demonstrated enhanced selectivity in the separation of H2/N2 and CO2/N2 pairs. It was found that a special effect of the vapors used for membrane saturation is associated with their molar volume. The solubility and diffusion coefficients of N2 and CO2 were obtained by Grand Canonical Monte Carlo (GCMC) and molecular dynamics (MD) simulations.
