US6004377A - System for collecting and refining SF6 gas ... 6 gas is collected from the inside of a gas insulated machine during maintenance and inspection and is refined. Compositions of the refined SF 6 gas are analyzed and confirmed to be reusable at the site. In the process of SF 6 gas collecting and refining, acidic gases are neutralized and removed by a dry method using filters and the refined SF 6 gas is collected in a collecting tank.
