Regarding the pressure relief valve issue
Thread Content
I work with gas processing; the raw gas volume is 17 kilograms, and the pressure in my processing system is around 10 kilograms. Is it necessary to install additional equipment to reduce this pressure? Is it enough to just use a pressure relief valve? This post was last edited by WSL01218 on 2009-2-5 14:15]
Install a self-acting pressure relief valve; a safety valve should be placed after the valve to prevent the system from overpressuring. It is necessary to know the system’s gas consumption levels – minimum, normal, and maximum – in order to select the appropriate pressure regulator.
If it is a combustible gas, a flame arrester should be considered along with the installation of a safety valve.
Combining the second and third floors solves this problem comprehensively.
For flammable, explosive, or highly toxic gases, the outlet of the safety valve should be connected to a safety waste gas treatment system such as a flare or a high-point vent, etc. It is necessary to consider and analyze whether a buffer device is required after the self-acting pressure relief valve.
When installing pressure increase and decrease valves, it is necessary to ensure that the pipes are not too long, as longer pipes are prone to vibration, which can lead to stress fatigue and eventual cracking of the pipes over time.
Add a pressure relief valve; if the material may contain oils, a filter can also be installed before the pressure relief valve.
What is the mechanism and principle of a flame arrester?
