Diaphragm compressor compression ratio?
Diaphragm compressor compression ratio?
(OP)
Any thoughts on what the maximum compression ratio should be for a diaphragm compressor (metal diaphragms)? Assume hydrogen gas.
Alternatively, how many stages would be required to take gas from 100 psig to 6000 psig?

RE: Diaphragm compressor compression ratio?
Hence, it wont be possible to approximate this as a typical recip compressor to get this information you're looking for, to my knowledge. Best to talk to the compressor vendors.
In the final stages of compression, the polytropic exponent n for H2 gas at 6000psig would be well off the value at low pressures. Dont know if process simulators can predict the corresponding adiabatic k value correctly at this pressure. Thats another reason to defer to what the vendors have to say.
