Assume a centrifugal compressor with discharge pressure (design) ~ 18 Barg.
Compressed stream is cooled and then fed into turbo-expander.
Outlet of the expander is connected into vessel with three discharge: one into next expander and two another streams goes into exchanger, the vessel and downstream design pressure is ~ 6 Barg.
Issue is that vessel has not any blocked outlet PSV.
Can I take credit for this arrangement (multiple outlet) to avoid blocked outlet case?
