    sulfur hexafluoride is found in the exhaust streams at low concentrations under 1%, its partial pressure driving force through the membrane is minimal, and conversely, its recovery in the non-permeate stream of the membrane is very high. Another system advantage is that air is recovered in the permeate stream at nearly atmospheric pressure

  • Toxic substances list: sulphur hexafluoride - Canada.ca

    Sulphur hexafluoride (SF 6) is a synthetic (i.e., human-made) gas that is colourless, odorless, non-toxic (except when exposed to extreme temperatures), and non-flammable. It is heavier than air and hence stays close to the ground upon release which can cause death by suffocation if large quantities are involved.
