sf6 gas Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of Sulfr hexafluorideChemical Properties of sf6 gas GasElectrical Properties of Sulfr hexafluoride Gassf6 gas or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that sf 6 gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very r...

Overview of Greenhouse Gases | Greenhouse Gas (GHG) Emissions

1 Atmospheric CO 2 is part of the global carbon cycle, and therefore its fate is a complex function of geochemical and biological processes. Some of the excess carbon dioxide will be absorbed quickly (for example, by the ocean surface), but some will remain in the atmosphere for thousands of years, due in part to the very slow process by which carbon is transferred to ocean sediments.

The tubes are pressurised with a N2/Sulfr hexafluoride gas to provide the main insulation. The main advantage of GIL is that a higher cable rating can be achieved than with solid insulation cables and the terminations at the cable ends are less complex and less prone to failure. Fig. 1 shows a GIL system in the process of installation [2].

What gases are greenhouse gases? – Jean-Marc Jancovici

Aug 01, 2007 · The definition of a greenhouse gas is at the same time very simple and very complicated for the ordinary man (or woman !) : such a gaz is “just” a gas mixed in the atmosphere that absorbs the infrared radiation emitted by the earth’s surface.

Liquefied Natural Gas (LNG) | Department of Energy

Liquefied natural gas (LNG) is natural gas that has been cooled to a liquid state, at about -260° Fahrenheit, for shipping and storage. The volume of natural gas in its liquid state is about 600 times smaller than its volume in its gaseous state. This process makes it possible to transport natural gas to places pipelines do not reach.
