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 کاملGlobal emissions of hydrogen chloride and chloromethane from coal combustion, incineration and industrial activities: Reactive Chlorine Emissions Inventory
Much if not all of the chlorine present in fossil fuels is released into the atmosphere as hydrogen chloride (HC1) and chloromethane (CH3C1, methyl chloride). The chlorine content of oilbased fuels is so low that these sources can be neglected, but coal combustion provides ignificant releases. On the basis of national statistics for the quantity and quality of coal burned during 1990 in power a...
متن کاملGlobal emissions of refrigerants HCFC-22 and HFC-134a: unforeseen seasonal contributions.
HCFC-22 (CHClF2) and HFC-134a (CH2FCF3) are two major gases currently used worldwide in domestic and commercial refrigeration and air conditioning. HCFC-22 contributes to stratospheric ozone depletion, and both species are potent greenhouse gases. In this work, we study in situ observations of HCFC-22 and HFC-134a taken from research aircraft over the Pacific Ocean in a 3-y span [HIaper-Pole-to...
