Assessment of sf6 emissions tanks

Assessment of sf6 emissions tanks

In 2011, the maximum allowable emission rate will be 10%, stepping down one percent each year until 2020 when there will be a 1% maximum allowable emission rate. Emission rates will be determined by dividing a utility's annual pounds of SF6 emissions by the utility's average switchgear system's (designed) capacity to contain SF6.

    Jun 23, 2011Abstract. Attempts to evaluate the sulphur hexafluoride (SF 6) tracer technique to estimate CH 4 emissions from ruminants have yielded mixed results. These studies either used SF 6 permeation tubes with a long history of use in animals, involved small number of animals or used partial animal enclosure.Cited by: 93

  • Assessment of the Sulfur Hexafluoride (SF6) Tracer

    ABSTRACT. A commonly used method of measuring enteric methane (CH 4) emissions from ruminants is the SF 6 tracer technique that measures respired and eructated CH 4 However, within the animal, a small proportion of CH 4 is produced post‐ruminally and some of this may escape through the rectum. The comparison of emissions using a chamber technique that measures all enteric CH 4 losses, and the SF 6 tracer technique, could give some insight into the magnitude of post‐ruminal emission.Cited by: 122

    The SF6 tracer technique underestimated CH4 emissions on average by 4% relative to the chamber technique. This difference was not significant (P 0.05) and suggests low post-ruminal CH4 emissions.

  • Methane emissions from above ground open manure

    Estimates of methane (CH4) emissions from slurry tanks or lagoons in the past have been made primarily by using chamber techniques, which are point specific and interfere with conditions at the slurry-atmosphere interface. This study is based on the use of sulphur hexafluoride (SF6) as a tracer gas to estimate CH 4 transport from the slurry surface.
