Action on New Zealandmost potent greenhouse gas | Beehive

The total stock of sf6 gas in New Zealand in 2002 was estimated by Transpower to be less than 40 tonnes. A detailed study carried out by CRL Energy Ltd on Sulfr hexafluoride emissions as part of the 2004 NZ Inventory of Greenhouse Gas Emissions gives a more accurate estimate of the total national stock of 33.2 tonnes in 2003.Get price

New Zealand’s total greenhouse gas emissions by sector

The most recent inventory report covered the following direct greenhouse gases: carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (sf 6). Only emissions and removals of these six direct greenhouse gases are included in the national greenhouse gas total.Get price

Title Recovery of sf6 gas from N-2/sf6 gas gas mixtures by using a

tivity, as explained in Fig. 2. When a pressurized N2/sf6 gas gas mixture is fed from the inlet into each of the hollow fibers, the gas species of larger permeation rate (N2) penetrates the membrane radially and fills the shell. Although the gas is re-moved through the exhaust tube, it contains a small amount of gaz sf6, which results in the recovery loss. The gas remainingGet price

Guidelines – Sulphur Hexafluoride Management

insulation gas sulphur hexafluoride (sf6 gas). insulating gas is an inert gas, but decomposed components (as a result of electrical arcing or naked flames) are toxic and hazardous. It therefore warrants methodical and careful handling. Sulphur hexafluoride is a greenhouse gas, and wilful venting to the atmosphere is illegal (refer to Section 9).Get price
