Sulfur hexafluoride purification from mixtures with air: a

Studies were made of the purification of SF/sub 6/ vapor contaminated with air for application at the Holifield Heavy-Ion Research Facility. Liquefaction appears to be a good method for recovering about 90% of the SF/sub 6/ if it is badly contaminated (15% air), and an even greater fraction can be recovered from mixtures containing less air.Get price
