Greenhouse Gas Reductions: Sulfr hexafluoride (Multimedia) | ScienceCinema

Apr 20, 2012 · Argonne National Laboratory is leading the way in greenhouse gas reductions, particularly with the recapture and recycling of sulfur hexafluoride (sf 6). sf 6 is a gas used in industry as an anti-arcing agent. It is an extremely potent greenhouse gas — one pound of insulating gas is equivalent to 12 tons of carbon dioxide. While the U.S. does not currently regulate insulating gas emissions, Argonne is proactively and voluntarily recovering and recycling to reduce sf 6 emissions.Get price

Environmental ImpactReducing DowntimeHigh-End Optical Gas ImagerSulfr hexafluoride is over 23,000 times as potent as carbon dioxide as a greenhouse gas, so SSEPD wants to make sure that gaz sf6 assets are carefully managed. "We take our safety and environmental responsibilities very seriously, with regular maintenance and protection of equipment. We have a very large fleet of switchgear and we work constantly to ensure its safe operation," comments Tawanda Chitifa, Project Manager at SSEPD. As part of an internal R&D project, we investigated ways to improve our environmental impact. The challenge was to be more efficient in handling possible sf6 gas leaks. Thermal imaging cameras from FLIR have helped us reduce that risk, because they allow us to detect possible leaks quickly and with high certainty.” Clearly pinpoint leaks Conventional leak detection methods include the use of sniffers. While the use of sniffers can quickly detect that a leak is present, it can be difficult to pinpoint the source, according to Tawanda Chitifa. “The problem is that with a sniffer you...Get price

List Of Greenhouse Gases - WorldAtlas

IntroductionSafetyUsesPropertiesOzone presents itself in two forms, stratospheric and tropospheric. Stratospheric ozone occurs naturally. Tropospheric ozone, however, is a greenhouse gas that contributes to climate change. Humans produce this gas through industrial plants, chemical solvents, and burning fossil fuels. Prior to industrialization, tropospheric ozone was concentrated at 25 parts per billion in the atmosphere. Today, it is at approximately 34 parts. When O3 mixes with carbon monoxide, the combination results in smog. Taking public transportation, avoiding pesticides, and buying natural cleaning products are all ways to reduce ozone production. Nitrogen trifluoride is produced by industrial gas and chemical companies. It is recognized by the Kyoto Protocol as a greenhouse gas that contributes to global climate change. It has an atmospheric life of between 550 and 740 years. Under this environmental treaty, member countries have committed to reducing emissions of this gas.Get price
