KEPCO Develops sf 6 Recycling Device to Combat Greenhouse Gas

Korea Electric Power Corp. (KEPCO) announced on July 9 that it has developed a sulfur hexafluoride (sf6 gas) refining device which recycles sf 6 emissions from discarded shutters and transformers. Sulfr hexafluoride is a greenhouse gas whose global warming effects are 23,900 times those of carbon dioxide. gaz sf6 is used as an insulation material for high voltage power equipment due to its electrical insulation property.

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 of

The decline in total emissions—from 6,983 million metric tons carbon dioxide equivalent (MMTCO2e) in 2008 to 6,576 MMTCO2e in 2009—was the largest since emissions have been tracked over the 1990-2009 time frame. It was largely the result of a 419-MMTCO2e drop in carbon dioxide (CO2) emissions (7.1 percent). There was a small increase of 7 MMTCO2e (0.9 percent) in methane (CH4) emissions, and an increase of 8 MMTCO2e (4.9 percent), based on partial data, in emissions of man-made gases with high global warming potentials (high-GWP gases).
