<p>The device comprises a closed chamber (4) provided with a series of filters arranged in series on a path followed by a fluid within the chamber. The first filter has a bed of soda-lime and/or activated carbon. The second filter comprises activated alumina. The third filter comprises a molecular sieve. The device further comprises: a bed of activated carbon; a particle filter arranged downstream of the third filter and to the path followed by the fluid; and a unit (3) for moving the fluid through the chamber. The bed of soda lime is placed upstream of the activated carbon bed.

The device further comprises: a bed of activated carbon; a particle filter arranged downstream of the third filter and to the path followed by the fluid; and a unit (3) for moving the fluid through the chamber. The bed of soda lime is placed upstream of the activated carbon bed. The activated alumina bed is positioned downstream of the bed of soda lime and upstream of the bed of activated carbon. The bed of soda lime has a thickness that is twice of its width. The bed of activated carbon has a thickness of >= 60 cm. The bed of activated alumina has a thickness that is twice of its width. The molecular sieve has a thickness that is twice of its width, and a diameter of 4-5 Å . An independent claim is included for a method for regenerating, in a liquid phase, sulfur hexafluoride used to form an inert atmosphere in a closed chamber.</p> |
