“…Comparison with data from literature for ideal selectivity and permeability [36][37][38] show that much higher selectivity has been reached, but PIM-TMN-Trip outperforms all other membranes in terms of permeability. It must be stressed that previous studies sometimes showed an ambiguous influence of the relative humidity on the membrane permeability of SO2 [28,39], and this should be addressed in future studies.…”

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.

Gas permeation behavior through a specific type of polymeric membrane was investigated in this work. The main objective of our study was to determine gas permeation properties of a specific polymeric membrane over a range of operating pressures. The diffusive layer of this membrane consists of Butadiene-Sulfone block copolymer and demonstrates high chemical stability in corrosive media. Permeances were determined at the temperature of 35• C and pressures of 760, 1520, and 3040 cmHg for methane, carbon dioxide, and nitrogen. Gas permeances were also determined for actual binary mixtures of H 2 S/CH 4 . Average permeances of 23.17 and 3.75 GPU for H 2 S and CO 2 were achieved respectively, at the pressure range of 380-1140 cmHg. Calculated permeances by a model developed for this membrane in previous literatures have been compared with experimental data in this study and the agreement of the model with H 2 S/CH 4 mixture was also investigated. The results show that the agreement between the pure gas experimental permeances and the data from the model is more in comparison with the experimental gas mixture results.

Sulfur dioxide (SO 2 ) is the major air pollutant which is emitted from the power plant. In this study, hollow fiber membrane (HFM) separation process is applied for the improvement of SO 2 removal efficiency in the post-combustion gas. HFM was produced by dry/wet phase inversion method and then coated with Polydimethylsiloxane (PDMS). The membrane morphology and characterization were examined with help of scanning electron microscope (SEM), energy dispersion of X-ray spectroscopy (EDX), Fourier transform infrared (FT-IR) and atomic force microscopy (AFM). Polyethersulfone (PES) hollow fiber membranes were tested for the SO 2 /N 2 binary mixed gas separation. Single gas permeance of SO 2 , N 2 , and binary mixture gas (200 ppm of SO 2 ) separation experiment was initiated to observe membrane behavior according to temperature and pressure difference and retentate flow rate. As a result, permeance of SO 2 was 24.9-47.4 GPU and selectivity of SO 2 /N 2 was 1.6-4.2. From the mixture gas separation experiment, SO 2 removal efficiency increased according to stage cut and operating pressure.
