Hfc - 23 Emissions from Hcfc - 22 Production
The compound HFC-23 (Trifluoromethane or CHF3), a potent greenhouse gas with a 100-year global warming potential of 11,700, is generated as a by-product during the manufacture of HCFC-22 (chlorodifluoromethane or CHClF2). This paper outlines options and issues for good practice guidance in the national inventory management of HFC-23 emissions from HCFC-22 production. The issues presented are or...
متن کاملHFC - 23 ( CHF 3 ) emission trend response to HCFC - 22 ( CHClF 2 ) production and recent HFC - 23 emission abatement measures
HFC-23 (also known as CHF3, fluoroform or trifluoromethane) is a potent greenhouse gas (GHG), with a global warming potential (GWP) of 14 800 for a 100-year time horizon. It is an unavoidable by-product of HCFC22 (CHClF2, chlorodifluoromethane) production. HCFC22, an ozone depleting substance (ODS), is used extensively in commercial refrigeration and air conditioning, in the extruded polystyren...
متن کاملRecent increases in global HFC-23 emissions
[1] Firn-air and ambient air measurements of CHF3 (HFC23) from three excursions to Antarctica between 2001 and 2009 are used to construct a consistent Southern Hemisphere (SH) atmospheric history. The results show atmospheric mixing ratios of HFC-23 continuing to increase through 2008. Mean global emissions derived from this data for 2006–2008 are 13.5 ± 2 Gg/yr (200 ± 30 10 gCO2equivalent/yr, ...
