Load Sharing between 2 Nos. Centrifugal Compressors of Different Capacity and Discharge Pressure
Load Sharing between 2 Nos. Centrifugal Compressors of Different Capacity and Discharge Pressure
(OP)
Hello Everyone,
I am having 2 nos. of centrifugal compressors connected from same suction header at pressure of 10 kg/cm2g
Capacity of one compressor is 5 MMSCMD and have discharge pressure of 27 kg/cm2g and capacity of other compressor is 3.5 MMSCMD and have discharge pressure of 60 kg/cm2g.
Please advise me that, is load sharing possible between these two compressor and if possible then what is required for achieving the same in term of instrumentation.
regards
Sanchit

if the higher pressure compressor is variable speed, you might be able to reduce the speed enough to lower the discharge pressure down closer to the discharge pressure of the lower pressure unit.
this situation you ask about is more complicated that what can be answered in a forum though. you should engage the compressor experts within the company or the OEM that built the compressors.

These machines are compressing "gasses" that do not condense nor vaporize in the piping, correct? You are NOT trying to pump liquids?
