Sizing Up a Suitable Centrifugal Compressor
Sizing Up a Suitable Centrifugal Compressor
(OP)
Mates,
I would like to seek your expertise in assisting us how could we size up a suitable centrifugal compressor for our upcoming project.
The field parameter will be varying over 16 years period. The expected field parameter is as below:
0-6 year
The gas consists 98% methane.
What would be the suitable sizing as our clients is requesting for 2x50% operation with a spare location for 3rd compressor
in future. Recycling is allowed.

RE: Sizing Up a Suitable Centrifugal Compressor
Whatever the answer is, the range of flows and pressures is such that you will not be able to undertake this with any single machine or 2 x 50% without either grossly oversizing it or running at a very inefficient manner.
Your options are probably to size the initial machine for the start (peak flow) and then gradually either re-wheel the machine to add stages ( with intercoolers) or re-wheel or add upstream booster compressors with coolers once the main machine exceeds its operating window.
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
