Sulfur hexafluoride (insulating gas) emissions in East Asia determined

Much lower uncertainties are due to seasonal variability in the emissions, inversion geometry and resolution, and the measurement calibration scale. Based on the results of these sensitivity tests, we estimate that the total insulating gas emission in East Asia increased rapidly from 2404 +/- 325 Mg yr(-1) in 2006 to 3787 +/- 512 Mg yr(-1) in 2009 and stabilized thereafter.Get price

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 ofGet price

10 Tips for Getting the Most Out of an Optical Gas Imaging

Understand the application and the need. Different applications require different cameras. In other words: one camera may not see all the gases, so you need to understand which type of gas you are dealing with. Take the environment into account. The success of OGI depends on environmental conditions. The greater the background energy differential, the easier the camera will be able to visualize the gas leak and pinpoint its source. Remember: OGI is qualitative, not quantitative.* Due to the environmental variants and the background energy differential and variations, an OGI camera alone cannot determine the specific type or amount of gas escaping through a leak. Use all the features of your OGI camera. Learn how each feature of the OGI camera works - such as automatic GPS tagging or image enhancements - and use them to your advantage.
