We are looking at custom engineered package complying to Shell DEP.
This package is for BF with min design requirements of 75,000 Kg/hr and Suction/Discharge pressure 16/50 barg.
Is there any thumb rule/documentation/Journal/Symposium Published paper to estimate Total Installed Cost (TIC) of Process Gas Centrifugal Compressor package/MW driven by (1) Electric Motor with VFD and Gearbox (2) Non-condensing Steam Turbine and (3) Gas Turbine?
Will TIC include the...
It's 3 Compressor trains (3 x 33%) running simultaneously.
I have attached PFD.
Sorry, I didn't read the note in P&ID which says "Recycle Flow Control for Turndown operation shall be sized for 100% recycle of rated capacity of Compressor." So the answer lies in the note itself.

What can be the purpose of individual bypass valve (100% sized) across each anti-surge control valve (100% sized) on 2 x 50% process gas (LNG) single casing centrifugal compressors driven by Steam Turbine operating in parallel configuration with load sharing feature and on discharge pressure...
The radial split process gas centrifugal Compressor driven by non-condensing Steam Turbine is designed to be installed on Tabletop foundation in refinery.
In EPC stage during detailed engineering, Who (Civil or Piping or Rotating or Compressor Vendor or All together) normally will take a call...
Thank you both for the reply.
Most probably individual feeds from the common header (after the seal gas is conditioned via filters, dehydration, heaters etc) may have separate pressure let downs (or flow controls) and conditioned seal gas will have to be sized for the highest pressure required...
For Centrifugal Compressor in LNG application, can there be any situation where Common seal gas conditioning skid on multi-stage casings can not be used warranting to use separate seal conditioning skid for each casing?
This is generic question and I don't have details about the operating...
