How many folks are going to know to do that? How do you
know that you got contaminated propane? I can just see the
looks on the face of the guy at the hardware store when I ask
if I can dismantle his filling system to insert my filter
Maybe this is why my surveyor requested that I remove all
copper tubing in my propane system.

Or, one could make a filter filled with citric acid to trap the amonia.

I have spent many years teaching fire department and emergency
responders in
hazardous material responses. One very scary fact that I learned in the
Haz-Mat response area is that the railroads utilize the same rail tank
car
to hall both Propane and Ammonia. As a result it is possible to get a
propane cylinder filled with ammonia contaminated gas. The impact of
this
contamination is that ammonia very rapidly dissolves copper. The copper
Propane lines can leak explosive gas with even one contaminated propane
cylinder fill. Removal of all copper tube and fittings is recommended
to
prevent this possibility of a explosive propane gas leak.
