Discharging Refrigerant

[unixxx]

I'm at the stage in my project where I need to discharge the original refrigerant and I was wondering how you guys did it. I was thinking of using a BBQ propane tank but I just learned that they have one way valves are aren't really a safe thing to store refrigerant in. Which leads me to my question (if you're about to flame/be sarcastic about a certain answer than feel free not to reply) what did you guys do? Thanx.

One thing Gary suggested was discharge it through an open flame. I'm not sure what it does exactly but it pretty much stops the negative effects from the release.
I never got that far though, everything i've had developed leaks before it came time to remove it???

NOT A GOOD IDEA!!

For example, if the refrigerant was r22, commonly used in air conditioners, when it passed through the flame it would decompose into CHLORINE GAS and other harmful gases. Chlorine gas is very toxic and harmful, it was used in wwII warfare.

If you do have to vent it, vent it straight, and do it on a windy day. If it's r12 you better have it recovered. If the laws in your area mandate that you must recover refrigerant, have an HVAC tech recover it and in the future use propane because you can vent propane freely since it is a hydrocarbon and is non global warming/ozone harming.
