Greetings!
I am attempting to find an appropriate means to accommodate PSV relief of a caustic stream (in part steam) from the shell side of a heat exchanger for a fire case (>350 psig). I can't vent to atmosphere or hot tap into the flare header. I explored several prospects with upstream and downstream neighboring vessels, but the principle issues arising include incompatible operating parameters leading to continuous nuisance relief, and/or lack of needed vapor space (I can't relieve into liquid). Can anyone kindly offer comments or suggestions? Thanks much.
