For case 3, Sulphur Hexafluoride
concentration contours in ppm in the plane of sitting occupants is presented in figure 3(a) with average concentration of 4.
IMA also initiated a request for proposals to research for a substitute for the use of sulphur hexafluoride
other than sulphur dioxide, which is a known quantity but toxic.
(SF6) is a relatively expensive man-made chemical released by electrical substations where it is used as an electrical insulator in equipment that transmits and distributes electricity.
France's plan to combat the greenhouse effect is to enable France to respect its international commitments under the Kyoto Protocol (1997) and in the EU, whereby France must, by 2010, stabilise, at 1990 levels, its emissions of carbon gases (a term that covers the six greenhouse gases targeted by the Kyoto Protocol: carbon dioxide (CO2), methane (CH4), nitrous oxide (N20) and three groups of industrial halogenated gases, namely sulphur hexafluoride
(SF6), hydrofluorocarbons (HFC) and perfluorocarbons (PFCs).
The case concerned the release of sulphur hexafluoride
(SF6) gas from high voltage switchgear (HVSG) (a circuit breaker) being installed at London Gateway Port.
Limited Tenders are invited for Supply Of Sulphur Hexafluoride
(Sf6) Gas As Per Specifications Enclosed At Annexure-A And B
The proposals under consideration aim to reduce emissions of hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride
, powerful greenhouse gases covered by the Kyoto Protocol.
It also aims at regulating the labelling and elimination of products and equipment containing gas, notification on the use of these gases, the use of sulphur hexafluoride
, the sale of products and equipment containing these gases or which depend on these gases to work, and training and certification for personnel involved in those activities referred to in the text.
Product/Service/Works Keywords: Sulphur hexafluoride
The fluorinated greenhouse gases covered are hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride
This includes EU measures for phasing out the production and/or reducing the use, where feasible, of industrial fluorinated gases such as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride
The Kyoto Protocol, concluded in 1997 in the context of the United Nations Framework Convention on Climate Change sets targets and deadlines for developed countries to reduce emissions of six greenhouse gases (carbon dioxide (CO2), methane (CH4), nitrous oxides (N2O), hydrofluorocarbons (HFC), perfluorinated hydrocarbons PFCs and sulphur hexafluoride
