2019-4-25 · An emission factor is defined as the average emission rate of a given GHG for a given source, relative to units of activity. Global Warming Potentials The Global Warming Potentials used for presentation of CH4 and N2O in terms of CO2 equivalent are 21 and 310, respectively. For HFCs, PFCs, and SF6 the GWP values for a 100 year time horizon have

SF6 gas valves separating unit in buna faso

RF-300 Separating Series SF6 Recovery Device allows the preparation of used SF6 gas containing an inadmissibly high percentage of nitrogen or air to the desired quality so that the SF6 can be reused in gas compartments.The purity degree of the prepared SF6 gas corresponds to the IEC 60480 guideline for used SF6 gas.

Estimating Oceanic Primary Production Using Vertical

2018-7-28 · An autonomous underwater vehicle (Seaglider) has been used to estimate marine primary production (PP) using a coination of irradiance and fluorescence vertical profiles. This method provides estimates for depth-resolved and temporally evolving PP on fine spatial scales in the absence of ship-based calibrations. We describe techniques to correct for known issues associated with long

Peripheral airway involvement in asthma assessed by …

The aim of the study was to assess how deep into the acinar region the airway response to cold dry-air hyperventilation challenge (CACh) reaches in subjects with asthma of different severity. Peripheral airway function was measured using a single-breath sulphur hexafluoride (SF6) and helium (He) washout test and overall airway function by forced expiratory volume in one second (FEV1) at rest
