I am a bit puzzled. Someone told me that a discharge pipe of relief valve for pure hydrogen should be continiously purged with an inert in order to prevent a flammable mixture during venting. Without sufficient purging, air will be present in the discharge pipe. A flammable mixture could then be...
The API code states that the pressure drop of the tailpipe should not exceed 10% of the set pressure.
Why is this? I want to understand what happens when the 10% is exceeded.
Is there a file of website where relieve valve are described how they work and why pressure drop is important?
I am looking at a project to relocate the relief of a destillation column to safe location. Set pressure of RD = 0.5 bar. To reach safe location significant length of piping is required; about 60m (200 ft) of which 20m to go to higher altitude. the vapor relief is at boiling point (about 200...
