  • CDC - Mining - Sulfur Hexafluoride as a Mine Ventilation

    Sulfur hexafluoride (SF6) is an odorless, colorless, nontoxic gas that has found acceptance as a tracer gas in research on ventilation patterns, measurement of air leak rates, respirable dust reductions due to bagging hood modifications, and the study of airflows relating to gob boreholes. Following a short review of the SF6 sampling technique, this report describes recent Bureau of Mines projects in which SF6 was used successfully as a tracer gas, enabling researchers to acquire

  • Separation of SF6 from SF6/N2 mixture using metal–organic

    Feb 15, 2015 · To overcome this obstacle, Kwon et al. performed an SF 6 /N 2 separation (1.3 vol.% SF 6) using the pressure temperature swing adsorption (PTSA) process to desorb SF 6 efficiently. They obtained an SF 6 purity of 19.5% and a recovery of 50.1% at a 2.5 atm adsorption pressure and a 200 °C desorption temperature . However, a temperature swing in the adsorption separation processes increases energy consumption and the cost of equipment needed to control the temperature.
