Replace the nitrogen compressor with a hydrogen compressor
Thread Content
Is it possible? Could there be any impact due to the large difference in molecular weight?
It depends on the inlet and outlet pressure, temperature, and flow rate, as well as the sealing. A large difference in molecular weight shouldn’t be a major factor; it’s not like changing from hydrogen to nitrogen
Pay attention to sealing, material, air valves, explosion protection, etc
Due to the large difference in molecular weight, gas valves cannot be used interchangeably; in addition, explosion protection must be ensured
If the original piston ring sizes are used, the hydrogen pressure will be lower than that of nitrogen.
Is it a reciprocating machine or a centrifuge? ? ?
No, because each compressor is designed independently based on its operating conditions; the compression coefficients of the two types of compressors differ by too much! There’s no way to generate pressure at all!
