Issues with the safety line of spherical tanks
Thread Content
When the spherical tank is shut down and the material level reaches 2%, open the vent valve at the top of the tank to vent it to the safe level. Does the safety line here refer to the vapor equilibrium line?
No, it’s the torch vent line. You can use water to push it up; that way there’s no need to empty it
It is generally a bypass for the safety valve, with its outlet at the same location as the safety valve’s discharge point
Isn’t pushing with water also pushing against the torch? Don’t you also need to clear your mind?

First, vent it to the flare line; use the remaining water to push it out
