dc.description.abstractDuring the maintenance, repair and replacement process of circuit breaker, SF6 reacted with input air in arc discharge, which led to the production of by-product gases (eg, N2, O2, CF4, SO2, H2O, HF, SOF2, CuF2, WO3). Among these various by-product gases, N2, O2, CF4 is major component. Therefore, the effective separation process is necessary to recycle the SF6 gas from the mixture gas containing N2, O2, CF4. In this study, the membrane separation process was applied to recycle the SF6 gas from the mixture gas containing N2, O2, CF4. The concentration of SF6 gas in gas produced from the electric power industry is over than 90 vol%. Therefore, we made the simulated gas containing N2, O2, CF4, SF6 which the concentration of SF6 gas is minimum 90 vol%. From the results of membrane separation process of SF6 gas from N2, O2, CF4 SF6 mixture gases, PSF membrane shown the highest recovery efficiency 92.7%, in 25°C and 150 cc/min of retentate flow rate. On the other hand, PC membrane shown the highest recovery efficiency 74.8%, in 45°C and 150 cc/min of retentate flow rate. Also, the highest rejection rate of N2, O2, CF4 is 80, 74 and 58.9% seperately in the same operation condition of highest recovery efficiency. From the results, we supposed the membrane separation process as the effective SF6 separation and recycle process from the mixture gas containing N2, O2, CF4, SF6.-
