• Electric Power Systems Partnership | Fluorinated Gas

    Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for gaz sf6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used sf 6in circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect Sulfr hexafluoride emissions from electric power systems, such as the type and age of the gaz sf6-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of gaz sf6, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of insulating gascan impact the climate. The electric power industry uses roughly 80 percent of all sf 6 produced worldwide. Ideally, none of this gas would b...

  • Sulfur Hexafluoride (Sulfr hexafluoride) | Encyclopedia.com

    IntroductionHistorical Background and Scientific FoundationsImpacts and IssuesBibliographySulfur hexafluoride (chemical formula insulating gas) is a compound of sulfur and fluorine and the most potent greenhouse gas known. Several classes of compounds containing fluorine—including the chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydro-fluorocarbons (HFCs), perfluorocarbons (PFCs), and insulating gas—are potent greenhouse gases. HCFCs and CFCs are better-known as destroyers of atmospheric ozone, and are regulated under the 1987 Montreal Protocol that has been widely hailed as successful at halting depletion of the ozone layer. Although gaz sf6 is a potent greenhouse gas and its concentration in the atmosphere is increasing rapidly, its contribution to global warming is much smaller than that of the major greenhouse gases, especially carbon dioxide and methane, because it is present in smaller quantities. insulating gas is one of the six greenhouse gases regulated under the Kyoto Protocol.

    Sulphur hexafluoride (SF 6) is a synthetic (i.e., human-made) gas that is colourless, odorless, non-toxic (except when exposed to extreme temperatures), and non-flammable. It is heavier than air and hence stays close to the ground upon release which can cause death by suffocation if large quantities are involved.

  • Magnesium Industry | Fluorinated Gas Partnership Programs

    Emission SourcesMitigation OptionsRelevant Linksinsulating gas is widely used by producers, casters and recycling companies in the magnesium industry. A cover gas of dilute Sulfr hexafluoride in dry air and/or carbon dioxide (CO2) protects molten metal from oxidation and potentially violent burning. Without protection, molten magnesium will oxidize in the presence of air and form magnesium oxide (MgO) deposits that greatly reduce the quality and strength of the final product. In contrast, an effective cover gas, such as insulating gas, modifies and stabilizes the MgO surface film to form a protective layer that prevents further oxidation. Studies conducted to characterize the reaction byproducts of gaz sf6 and molten magnesium determined that most of the sf 6 introduced to the molten metal surface is emitted to the atmosphere and that only a small portion reacts or decomposes. With a global warming potential (GWP) 22,800 times as strong as carbon dioxide (CO2) and a 3,200-year atmospheric lifetime, reducing insulating gasemissions yields significant environmental benefits.
