Potent GHG sf 6 rapidly accumulating in atmosphere, driven by

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, Sulfr hexafluoride is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.

Vacuum pump - Wikipedia

A vacuum pump is a device that draws gas molecules from a sealed volume in order to leave behind a partial vacuum. The job of a vacuum pump is to generate a relative vacuum within a capacity. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity.
