SF6 recovery | GH

Although SF 6 is an excellent insulating and quenching medium it is very important to know that: . SF 6 is a fluorinated gas (F gas) with the highest global warming potential.; It is one of the six gases subject to monitoring under the Kyoto protocol. Relating to the greenhouse effect, 1 kg SF 6 corresponds to a GWP value more than 22,800 times higher than that of CO 2.

Assessment of the sulphur hexafluoride (SF6) tracer

1. Introduction. Extensive developments in inventory and mitigation research on enteric CH 4 emissions completed in New Zealand over the last 10 yr have been based on use of the sulphur hexafluoride (SF 6) tracer technique (Johnson et al., 1994).A major issue of the tracer technique is large among- and within-animal variability in CH 4 emission estimates (Pinares-Patiño and Clark, 2008
