I just stumbled upon this page: How to Fill a Propane Tank With CO2 | eHow.com which suggests you could refill a propane tank with co2. Since all the valves are the same, I'm sure it can physically be done, my question is how safe would this be to use for kegging. I have several empty propane tanks of various sizes, and am considering taking them up to my local welder supply shop to have filled with CO2. My main concerns are: is this empty tank really empty, or is there still some liquid propane in it? and is this tank gonna have an odor from the old propane?
