Sulfur hexafluoride purification from mixtures with air: a

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. In cases where liquefaction is insufficient by itself, adsorption of SF/sub 6/ on activated carbon at -50/sup 0/F is promising.Get price
