Residual gas emissions in SF6 recovery

Introduction

Old devices:

Residual SF6 gas at

50 mbar 0.304 g / l

1 m³ = 304 g

Residual SF6 gas at

20 mbar 0.120 g / l

1 m³ = 120 g

Residual SF6 gas at

5 mbar 0.030 g / l

1 m³ = 30 g

Stipulated final vacuum as per IEC 62271-4,

Chart 6, No. 4 for gas recovery: ≤ 20 mbar

Residual SF6 gas at

1 mbar 0.006 g / l
