Modeling and simulation of Sulfur Hexafluoride (SF 6

Liquid sulfur hexafluoride (SF 6) contains carbon tetrachloride (CF 4) and air as main impurities. It is very difficult to remove these impurities by using a catalyst column or an adsorption column. In this work a new purification method for SF 6 mixture based on batch distillation is proposed.

Sulfr hexafluoride Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of Sulfr hexafluorideChemical Properties of gaz sf6 GasElectrical Properties of gaz sf6 GasSulfr hexafluoride or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that insulating gas gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very r...

Dielectric Properties of Gas Insulated Bus Applying Low sf6 gas

Abstract. SF 6 gas has widely been used as the insulating and arc-quenching gas for power apparatus such as gas insulated switchgear (GIS) and gas insulated bus (GIB), which contribute to realize compactness and high reliability of the apparatus. However, SF 6 substitutes such as N 2 /SF 6 gas mixtures are now in great concern to reduce the consumption and emission of SF 6 to the atmosphere, 1 since SF 6 is identified as one of the potent greenhouse gases.

Liquefied natural gas (LNG) | Shell Global

This happens in heat exchangers. A coolant, chilled by giant refrigerators, absorbs the heat from the natural gas. It cools the gas to -162°C, shrinking its volume by 600 times. This turns it into a clear, colourless, non-toxic liquid - liquefied natural gas, or LNG – that is much easier to store and transport.
