  • 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.

  • The Low Temperature Liquefaction Characteristic Test of

    The results show that SF6 gas is easier to liquefy in cold area, and the liquefaction temperature of SF6 gas is in proportion to gas pressure. So the liquefaction temperature of electric equipments operated in cold area should not be higher than the lowest area temperature. Otherwise, measures must be taken to prevent SF6 gas from liquefaction.Author: Guo Xing Li, Lin Li, Zi Qiu Jiang
