Sizing Up a Suitable Centrifugal Compressor

Sizing Up a Suitable Centrifugal Compressor

Sizing Up a Suitable Centrifugal Compressor


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
85 deg F
7-10 year[indent]51-145MMscfd
85 deg F
10-16 year[indent]15-50MMscfd
270/145psia[indent]85 deg F

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

Compressing to what pressure on the outlet?

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.
