Performance of PDMS/PEI membrane for separation of F-B/F-C gas system
The separation of F-B/F-C gas mixture using a home-made spiral PDMS/PEI membrane module has been studied. Experiments were conducted under different operating conditions. Permeability of each component through the membrane and the influences of stage-cut and feed pressure on separation performance were analyzed. The results showed that the average separation factor reached up to 2.34 and the concentration of F-C was enhanced from 78.89％ in feed gas to 90.03％ in retentate gas under the pressure of 0.6MPa at 22 ℃. In addition, simulation has been done basing on the experimental data. According to simulation, the concentration of F-C in retentate gas could reach up to 98.9％ by connection of two membrane modules with different areas. Meanwhile, the performance degeneration of membrane was tracked by observing the variation of nitrogen permeation rate.
