Dear all,
I came across in one of the project document, where vessel is feed from the outlet stream(#1) of centrifugal pump. PRD set pressure at pump outlet piping is 70 kg/cm2g(other stream #2).
Vessel design pressure is 35 kg/cm2g and protected by PRD set by 35 kg/cm2g.
As per the client standard, vessel design pressure at pump discharge should be based on shut-off pressure of the pump.
I believe that there will not be any safety concern if vessel PRD is sized for inlet feed rate, however, it does not comply with standard.
I would like to know your comments on vessel design pressure/PRD set pressure considered in the design, is it correct, any concerns?
(please refer the attached sketch)
Thanks,
Shantanu Ghag.
