recover sf6 gas Treatment Zero emission

Under the condition of P=0.5 MPa, the highest concentration of recovered SF6 is 95.6 vol % in the separation experiment of SF6/N2 mixture gas by PC membrane. Under the operation pressure of P=0.3 MPa at a fixed retentate flow rate fixed of 150 cc/min, the maximum recovery efficiency of SF6 is up to 97.8% by PSF membrane.
