Sulfur hexafluoride (sf 6) emission estimates for China: an

Abstract: Sulfur hexa fluoride (sf 6) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, gaz sf6 emissions from China were inventoried for 1990–2010 and projected to 2020. Results reveal that the highest gaz sf6 emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector, the semiconductor manufacture sector and the sf6 gas production sector (each about 10%).

Electric Power Systems Partnership | Fluorinated Gas

Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for Sulfr hexafluoride, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used insulating gasin circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect sf 6 emissions from electric power systems, such as the type and age of the sf6 gas-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of Sulfr hexafluoride, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of sf6 gascan impact the climate. The electric power industry uses roughly 80 percent of all gaz sf6 produced worldwide. Ideally, none of this gas would b...
