Should pressure vessels be equipped with safety valves or not?
Thread Content
I’m seeking advice from everyone. A jacketed reactor is considered a pressure vessel, but it operates at atmospheric pressure – no pressure is applied. It has a venting system; is it still necessary to install a safety valve on this reactor? If it is not specified, which provision can be referred to? Thank you.
It is necessary; the pressure vacuum valve protects pressure vessels
Is the purpose to prevent explosions or to prevent deflation?
It is also explosion-proof, while being resistant to negative pressure.
At normal pressure, abnormal pressures or pulsating pressures can still occur, especially during maintenance or when testing the system’s airtightness, when abnormal overpressures may arise as well.
Additionally, the reaction vessel operates in batch mode, using toluene as a Class A solvent, at an operating temperature of 110 degrees. I designed a safety valve, but the owner doesn’t want to install it. Seeking advice.
