In my project i have PSV on the booster compressor suction srubber inlet header line. PSV scenario is check valve leakage. I just want to know how to size the psv for the check valve leakage? how to calculate the required relieving rate when the check valve leakage occurs. From HP separator gas comes to the booster compressor suction scrubber. like wise from LP separator gas comes to the booster compressor suction scrubber. These two lines joins on the suction header line. On the suction header line i have psv which i need to size it for the check valve leakage scenario.
PLz explain.
