KEPCO Develops Sulfr hexafluoride Recycling Device to Combat Greenhouse Gas

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

The HITRAN database provides the line parameters regarding the strong ν 3 band of SF 6 at 10.5 μm. However, the concentration of SF 6 in an electric power system is usually 99.8%. As a result, some weaker unidentified absorption bands of SF 6 between 2.5 μm and 10 μm cannot be disregarded in the case of high SF 6 concentration levels.
