gaz sf6 gas handling - DILO

Thereby the gas flows automatically via dry and particle filters which effectively adsorb decomposition products and moisture from the gas. During the gas recovery process the SF 6 is stored either in gaseous or in liquid form. Furthermore, the air is evacuated from gas compartments after maintenance works.

New SI-traceable reference gas mixtures for sulfur

In this method a highly concentrated mixture is produced by spiking a purified synthetic air (matrix gas) with gaz sf6 from a permeation device. The mass loss of Sulfr hexafluoride in the permeation device is observed by a magnetic suspension balance. In a second step this mixture is diluted with matrix gas to the desired concentrations.

Jan 15, 2021 · The liquefaction process (Fig. 1b) can also be employed to recover SF 6 from gas mixtures. This process is based on the liquefaction of more condensable component (SF 6 in this case) in the feed gas. The process is typically useful if subsequent transportation is needed as the amount of SF 6 that can be stored in a single cylinder in liquid phase is about four times larger than that in gaseous phase [28] .

May 15, 2014 · Therefore, an efficient method for separating and recovering SF 6 from gas mixtures is urgently needed to prevent the release of SF 6 into the atmosphere. Liquefaction has been used for these separations, but this process is energy intensive, especially when the SF 6 concentration is very low . Adsorption-based processes, such as pressure-swing adsorption (PSA), might be good alternatives because they require much less energy than liquefaction.
