Hi there,
I am looking at the attached centrifugal compression system and I am considering the unmitigated consequences (ignoring all trips/interlocks - there are limit switches on the HGB valves and high temperature trips that trip the compressor but these are assumed to not act) of the hot...
I am trying to get my head around one aspect of surge control:
System – Single stage centrifugal compressor with discharge cooler and suction scrubber. There is a PCV controlling the pressure downstream of the discharge cooler and there is a surge control recycle line downstream of the cooler...
Hi,
In a LOPA for a certain scenario, a hazard is protected by the BPCS which closes a control valve. It is also protected against by a independent trip which closes a separate ESD valve. Can an operator response be credited as an IPL if the response is independent of the other IPLs EXCEPT that...
Hi,
A P&ID states the duty of a screw compressor as “x CFM at y psig”, compressing atmospheric air. To work out the compressor mass flow rate for start-up conditions where the downstream pressure is also at atmospheric then I would use x and y? Is this correct or should the mass flow rate be...
