【答案】应助回帖

Possible sources of unknown flare flow are:
• Relief valve leakage due to corrosion, fouling, or from mechanical damage.
• Block valves sealing poorly due to any number of problems, including normal wear of the valve seat.
• Poor pressure control resulting in cyclic pressure swings.

30金币,4句)The previous section described the method of tracking down where fugitive flows are originating. Once it is determined which unit(s) are contributing to the flare flow, each PSV, block valve or relief valve can be individually tested to determine which are leaking.
Tracer flow (or lack thereof) is used to determine which pressure relief devices are leaking and by how much. There are several possible scenarios to successfully test pressure relief devices.
