Abstract
A separation, purification and recovery method of SF, HFCs or PFCs is disclosed, which comprises a step for forming a gas hydrate including components in addition to SF, HFCs or PFCs. It is possible to separate and recover fluoro-gas at a much lower cost as compared to a conventional method for thereby obtaining an economical effect and preventing an emission of SF, HFCs or PFCs which corresponds to Non-COhaving a higher earth warming index, which leads to preventing an earth warming phenomenon. So, the present invention might be widely applied.
