I'm kind of out in the country a ways and have an unused propane tank in the back yard. It's close to 200 gallons or so and would be perfect if I could put a pump and motor on it. I know it's "empty" but is there a way to purge it completely? Also, could the propane from its years of use have embedded in the pores of the metal so that there's any danger to making this kind of change? I'm sure there are no leaks and if I could make this change there would be no more problems with my compressor keeping up with my use. I killed my compressor before (it was homemade) from overheating but rebuilt the pump with new rings, reed valves and proper gaskets and it's on a 60 gallon tank being pushed with a 6.5 hp motor which is fine for air wrenchs etc., but I have a lot of sandblasting to do so I've gathered a bigger pump and motor and am looking at this propane tank so...are there any good reasons not to try this tank?
Thanks guys and gals.

Now i'm no expert but i have seen this done with smaller tanks being used as a pressure tank for air.(the size for backyard barbques)
As far as i know the metal wouldn't be porus to hold any residual . Do make sure the tank is empty though ofcourse. Remove the filler/regulator valve.
I would just plumb the old tank into the compressor tank, thus having 2 air tanks, then once you start blasting there will be a head of pressure.
