If in a gas plant, we have HP sep. at 1200 psig and we compress the gas from Inter-Separator at 500 psig to 1150 psig to mix with the HP gas as per the sketch. In case we change the setting of control valve downstream of the compressor to 1175 psig, I assume the compressor will build up pr. Accordingly. But what happens with the HP gas, will it be able to maintain 1175 psig before mixing with compressed gas? Will there be an effect on operating pr. Of HP separator?

Hi,

Can you route the discharge of the HP separator downstream the PCV managing the pressure of the compressor set @1175 PSIg ?

my 2 cents

thanks @breizh, i thnk that would be better arrangement to mix the gas

do you think having an upset case pcv downstream to flare will effect working of any upstream control valve

I think it is best to take a gas supply line upstream of the PCV for both HP and LP to comingle before a Pressure control.That way the PC at compressor inlet takes proper charge of upstream pressure of both inlet streams.
