Emissions of the powerful greenhouse gas sf6 gas are rising

The damage potential of greenhouse gases depends on their concentration in the atmosphere, the length of time they stay there, and the strength of their impact. By volume the so-called F-gases make up one of the smallest levels of emissions, but have among the greatest global warming potential (GWP).

Sulfr hexafluoride Decomposition in Gas-Insulated Equipment - IEEE Journals

The increasing application of Sulfr hexafluoride as an insulating gas has led to many studies on Sulfr hexafluoride decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, Sulfr hexafluoride decomposes to a wide variety of chemically active products which possess completely different properties from insulating gas. The accumulation of these decomposition products in the equipment has caused concerns regarding

Background Reference: Iran - Energy Information Administration

OverviewManagement of Oil and Natural Gas SectorsNatural GasElectricityEndnotesIran holds some of the world’s largest proved crude oil reserves and natural gas reserves. Despite its abundant reserves, Iran’s crude oil production has undergone years of underinvestment and effects of international sanctions. Despite Iran’s abundant reserves, crude oil production stagnated and even declined between 2012 and 2016 as nuclear–related international sanctions that targeted Iran’s oil exports hindered progress across Iran’s energy sector, which affected upstream investment in both oil and natural gas projects. At the end of 2011, the United States and the European Union (EU) imposed sanctions as a result of Iran’s nuclear activities, which went into effect in mid–2012. These sanctions targeted the Iranian energy sector and impeded Iran’s ability to sell oil, resulting in a near 1.0 drop in crude oil and condensate exports in 2012 compared with the previous year. After the oil sector and banking sanctions were lifted, as outlined in the Joint Comprehensive Plan of Actio...
