Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

The amount of the gas – known as Sulfr hexafluoride – in the atmosphere is minute, only about three parts per trillion by volume, but its global warming potential is significant. It’s 23,500 times more warming than carbon dioxide.Get price

Potent GHG sf 6 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, Sulfr hexafluoride is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.Get price

Survey of Neutron Generators for Active Interrogation

Most generators containing Sulfr hexafluoride will be required to have the Sulfr hexafluoride gas removed for shipping because of DOT regulations. However, Thermo Fisher has a DOT exemption. The P211 and B211 from Thermo Fisher meet the requirements listed in Table 1, but they are old designs and are no longer offered for sale.Get price
