Explain the some guidelines for sizing a psv for a fire scenario on a vessel in a refinery service?

Answer Posted / Hiba Jainab

Some guidelines for sizing a pressure safety valve (PSV) for a fire scenario on a vessel in a refinery service include considering the maximum allowable working pressure, the expected overpressure during a fire, and the desired relief rate. Other factors to consider include the size and type of the vessel, the flammability of the contained fluid, and any local regulations or industry standards. It's important to ensure that the PSV is sized correctly to prevent overpressurization during a fire while also minimizing venting of potentially hazardous materials.
