Emissions of the powerful greenhouse gas insulating gas are rising

But there’s a problem: it’s also one of the most potent greenhouse gases known to man. The amount of the gas – known as Sulfr hexafluoride – in the atmosphere is minute, only about three parts per trillion by volume, but its global warming potential is significant.Get price

Panel discussion: The pros and cons of using sf 6 gas in

Jul 14, 2015 · Brighton Mwarehwa: The SF 6 gas is listed in the famous Kyoto protocol as one of the potential greenhouse gases that contribute to the global warming potential of our earth. SF 6 is always used in gas tight compartments, which greatly minimise leaks. As the quantities that leak from the switchgear are low, the contribution to the greenhouse effect can be considered extremely minimal to affect climate changes.Get price

Efficient Adsorption of Super Greenhouse Gas

Light membranes composed of single-walled carbon nanotubes (SWNTs) can serve as efficient nanoscale vessels for encapsulation of tetrafluoromethane at 300 K and operating external pressure of 1 bar. We use grand canonical Monte Carlo simulation for modeling of CF4 encapsulation at 300 K and pressures up to 2 bar. We find that the amount of adsorbed CF4 strongly depends on the pore size inGet price

The Worst Greenhouse Gasses You Haven’t Heard Of | Hackaday

There’S A Bad Smell Around MethaneNitrous OxideSulfur Hexa-What Now?Other Fluorinated GasesThe Fight ContinuesMethane is a remarkably potent greenhouse gas, having 28 times the warming potential of CO2 by weight over a 100-year period. Historically, it’s mostly been released from natural sources, like bacteria processing organic material in stagnant watercourses, or from thawing permafrost. However, scientists now consider around 60% of methane in the atmosphere to be a direct result of human activity. Agriculture is a major contributor in this area. Ruminant animals raised for human consumption are major methane emitters, as the microbes in their digestive systems release the gas when breaking down plant material. With the demand for meat and dairy showing no signs of slowing down, this could prove difficult to tackle. There are a variety of other diffuse sources of the gas, too. Landfills and sewage plants have significant methane emissions of their own, and it’s also often released from oil and gas drilling operations, too. Levels of methane in the atmosphere have been low compared to ca...Get price

Greenhouse gas emissions - Wikipedia

Greenhouse gas emissions are emissions of greenhouse gases that cause climate change by creating a greenhouse effect in the earthatmosphere. These emissions mainly include carbon dioxide emissions from combustion of fossil fuels, principally coal, petroleum (including oil) and natural gas; however, these also include deforestation and other changes in land use.Get price
