A tamasium extractor is capable of " cleaning " butane, to what extent or with what process I'm unsure of, since I don't own one or know anyone with one myself. I assume as you said it would distill, with the intention of cleaning up the butane that it holds and reuses, or I guess buying cheap butane and turning it into lab quality n- butane. But either way the "cleaning" process would be identical to doing a run using the device, without actually running any material through it, so therefore if you run nothing but butane and extract a small amount of goo, you have successfully cleaned your butane, which is where the closed loop system comes into play, it allows you to evaporate the butane without losing it, which is key, because your nice clean butane doesn't do you any good all Willy nilly in the atmosphere.
