SF6-alternative gases Disposal for subway

SF6, Sulfur Hexafluoride . Sulfur Hexafluoride (SF6) is an inorganic, colorless, odorless, and non-flammable gas. SF6 primary use is in the electrical industry as a gaseous dielectric medium for various voltage circuit breakers, switchgear and other electrical equipment, often replacing oil filled circuit breakers (OCBs) that can contain harmful PCBs.

    A service cart for Alternative Gases has the same functions as for SF 6. This service cart is used for the recovery of Alternative Gases from the gas compartment down to a final vacuum of < 1 mbar. The gas is automatically passed through dry and particle filters, which effectively adsorb decomposition products and moisture from the gas.

    Sulfur hexafluoride is a sulfur coordination entity consisting of six fluorine atoms attached to a central sulfur atom. It is the most potent greenhouse gas currently known, with a global warming potential of 23,900 times that of CO2 over a 100 year period (SF6 has an estimated lifetime in the atmosphere of between 800 and 3,000 years).

    Disposal Sulfur hexafluoride is one of the most potent greenhouse gases, with a global warming potential of 23,900 times that of CO 2 . However, given the low amounts of SF6 released compared to other greenhouse gases such as carbon dioxide, its overall contribution to global warming is estimated to be less than 0.2%.

  • Have you Heard of the Most Powerful Greenhouse Gas we

    Oct 23, 2018Among all the greenhouse gases that exist, CO 2 gets the most attention. Today, we bring a different perspective. Think about everything that you know about CO 2 and multiply it by roughly 24,000. This is how much a gas called SF6 (sulphur hexafluoride) is stronger than CO 2 in terms of global warming potential.
