sf6 emissions process Quantitative

Total SF6 emissions equal 7160 tonnes annually.1. SF6 is used extensively in equipment for the transmission and distribution of electricity. Emissions occur through leakage and maintenance losses. SF6 is also used as a cover gas to protect molten magnesium from oxidation. Emissions are caused during the production process when the gas is released into the atmosphere.

    Sulfur hexafluoride (SF6) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, SF6 will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought SF6 into the climatic impact discussion aimed at reduction
