Existing centrifugal compressor to be used for lower MW gas

[GasOilEng]

Hi;

I'd like to know how to check if our existing centrifugal compressor to be used from Gas MW of 40 kgmol/kg to 23 kgmole/kg using Aspen Hysys, see Attached PFD.

Check with the manufacturer, you'll need more than a pfd to sort that out

you have postings in the other page (Chem Eng). you should check with the equipment supplier. it has to do with the mechanical performance...

The aspen Hysys can generate a curve compressor lower and greather than that given by the supplier. But, but only two curves, in this case for example, 35 and 46. However, what I want is to create a curve of 22 to 25, in order to check what are consequences.
