I'm trying to get my head around a concept.
We use Industrial Gas cylinders filled with SF6 gas - the gas cylinder is 70-80% liquid and the rest is in a gaseous state.
If this is kept at a pressure of approx 40Bar and is passed through a regulator that allows the gas to be filled into a containment unit at 1bar -
How does the liquid SF6 become a gas when kept at the same temperature? Obviously the pressure inside the cylinder will decrease as the gas is released.
I realize the liquid freezes if the pressure drop inside the cylinder is too fast.
The pressure curve is as follows.
