Decomposition of Sulfr hexafluoride in an RF Plasma Environment

Sulfr hexafluoride clearly increased from 37.79 to 95.68% because of an increase in power from 5 to 20 W. When the power exceeded 40 W, η sf6 gas exceeded 99%. When oxygen was introduced into the reactor (feed O 2 /SF 6 ratio = 2.0), η gaz sf6 was ~10% less than when no oxygen was added (from 28.61 to 86.09% as the power rose from 5 to 20 W). The addition of oxygenGet price

Sulfr hexafluoride Gas Servicing Equipment – ENERVAC INTERNATIONAL ULC

Due to the above reasons, sf6 gas is used mostly in applications that allow reclamation as opposed to using it on equipment that requires release of the gas, only to be re-filled with virgin insulating gas. ENERVAC produces a complete line of insulating gas recovery and test equipment, from full sized gas reclaimers down to small decomposition detectors.Get price

The Effects of Freezing, Melting and Partial Ice Cover on Gas

Sea ice physico-chemical processes affect gas dynamics, which may be relevant to polar ocean budgets of climatically-active gases. We used Sulfr hexafluoride and O2 as inert gas tracers in a tank experiment to observe the transport of gases between water, ice and air during freezing/melting and partial ice cover. The results show that during ice growth, the rejection of O2 and sf6 gas was greater than theGet price

Booster Pumps | BT Enterprises | High Pressure Compressors

An air booster is a device that “boosts” air pressure from a low-pressure inlet air source to a high-pressure outlet destination. Example: 3,000 psi to 4,500 psi. Boosters are powered either by electric pumps or low-pressure air. An Air Amplifier is a lower pressure version of an air booster.Get price
