Abstract:
We simulate the relief scenario of loss of vacuum and show the relief system is adequate, and piping pressure drop is low.
Scenario:
Loss of vacuum with Helium (higher conductivity than air). Initial conditions: Saturated Nitrogen @ 1 psig. Saturated Liquid @ inlet and 60% vapor quality @ outlet (30% used in analysis to be conservative)
Relief Valves: two Anderson Greenwood 0.049 in^2 relief valves set to 150 psig. One @ supply side, one @ return (outlet) side.
