Patent Number Title Of Patent Date Issued
6723153 Isolation of SF6 from insulating gases in gas-insulated lines April 20, 2004
Gas mixtures of SF.sub.6 and N.sub.2 which have been used as an insulating filler gas for underground cables can be separated by use of a membrane separation in order to recover the SF.sub.6.
6706090 Method for recovering and/or separating sulfur oxyfluorides from gas mixtures March 16, 2004
A method for the recovery or separation of sulfur oxyfluorides from gas mixtures, in which the gas mixture passes through at least one adsorption stage or membrane stage containing or consisting of zeolites with a modulus >10. The sulfur oxyfluorides fixed to the adsorbent may be made
6454837 Separation of gases containing SF6 September 24, 2002
Gas mixtures of SF.sub.6 and N.sub.2, which have been used, for example, as an insulating filler gas for underground cables, for insulating-gas window panes or as a filler gas for car tires and SF.sub.6 /air mixtures which have been used as a protective gas when casting magnesium can be
6105631 Preparation of homogeneous gas mixtures with SF.sub.6 August 22, 2000
Homogeneous compressed gas mixtures with SF.sub.6 and a gas with a density at least 4 grams per liter lower can be prepared by using a mixing station with at least the following elements: a gas premixer in which the separate gases are brought together; a static mixer and/or a buffer tank
6083398 Process for the decoloration and detoxification of aqueous effluents July 4, 2000
Process for the decoloration and the toxification of highly polluted (COD.gtoreq.1000 mg/l) resistant aqueous effluents by an oxidation treatment of the effluents by hydrogen peroxide, continuously and in a homogeneous phase, at a pH of 2 to 5 in the presence of Fe ions and under irr
