New study on the use of the greenhouse gas sulfur

Mar 28, 2019 · Sulphur hexafluoride (gaz sf6) plays an important role as an insulating gas in electrical switchgear at various voltage levels when interrupting and diverting current flows. At the same time, it is one of the most effective greenhouse gases with a very long lifetime and, although the concentration of sf 6 in the atmosphere is currently still very low, it accumulates steadily over the years.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density ofGet price

Is the end coming for sulfur hexafluoride, the most powerful

Oct 15, 2020 · Current EU F-gas regulation prohibits the use of SF 6 in many non-electric applications, but not in MV switchgear. Today, about two thirds of the 15 million MV switchgear units installed in Europe (EU28) use SF 6. When the EU F-gas regulation was last revised in 2014, it was considered that no cost-effective and reliable alternatives to SF 6Get price

Uranium Enrichment | Enrichment of uranium - World Nuclear

International Enrichment Centres, Multilateral ApproachesEnrichment ProcessesEnrichment of Depleted Uranium TailsEnvironmental IssuesNotes & ReferencesFollowing proposals from the International Atomic Energy Agency (IAEA) and Russia, and in connection with the US-led Global Nuclear Energy Partnership (GNEP), there are moves to establish international uranium enrichment centres. These are one kind of multilateral nuclear approaches (MNA) called for by IAEA. Part of the motivation for international centres is to bring all new enrichment capacity, and perhaps eventually all enrichment, under international control as a non-proliferation measure. Precisely what "control" means remains to be defined, and will not be uniform in all situations. But having ownership and operation shared among a number of countries at least means that there is a level of international scrutiny which is unlikely in a strictly government-owned and -operated national facility. The first of these international centres is the International Uranium Enrichment Centre (IUEC) at Angarsk in Siberia, with Kazakh, Armenian and Ukrainian equity so far. The centre is to...Get price
