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

Controlled substances licence to import synthetic greenhouse

It is an offence under the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989 (the Act) to import, export and manufacture hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF 6 ), and nitrogen trifluoride (NF 3) without a controlled substances licence for synthetic greenhouse gases unless an exemption applies.

How Australia accounts for agricultural greenhouse gas

Agriculture Is An Important Source of Greenhouse Gas EmissionsNot All Greenhouse Gases Are EqualSome Emissions Are Not Counted as Agricultural EmissionsAgriculture was responsible for about 16% of Australia’s greenhouse gas emissions in 2013, and the sources (see Table 1) are: 1. 66.3% from enteric fermentation in ruminant livestock (eructation and flatulence) 2. 15.5% from agricultural soils 3. 10.8% from prescribed burning of savannas 4. 3.9% from manure management 5. 2.4% from liming and urea application 6. and the remainder from rice cultivation and field burning of agricultural residues. Livestock and the manure they create were the dominant source of methane, accounting for 52% of total national methane emissions, and agricultural soils were the dominant source of nitrous oxide, accounting for 62% of total national nitrous oxide emissions.Get price
