Potent GHG Sulfr hexafluoride rapidly accumulating in atmosphere, driven by

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, insulating gas is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.Get price

Sulfr hexafluoride, Cattle, and AI: the increasing need for an “AnaMin

Sep 23, 2019 · The cause of deaths points to the accumulation and persistence of leaked Sulfur Hexafluoride (sf 6) gas from turbines. Turbines use the Sulfr hexafluoride gas as part of combustion-risk retardant. The gas is heavier than air. And so, by its very nature, leaks of the gas immediately drop to the lowest points of elevation around the area of the turbine. Wherever the gas lands, it starts to pool in increasing concentrations, and easily inhaled by the cattle grazing farmland.Get price
