Problems with the air valves of reciprocating compressors? ?
Thread Content
We have a new hydrogen compressor in our facility; currently, a nitrogen valve is installed on it. Can it compress hydrogen now?
The difference in specific gravity is too large; have the manufacturing plant or design team carry out further calculations and checks.
It should be possible, but due to different compression coefficients, there are changes in temperature and pressure
Generally, nitrogen is used to purge hydrogen valves, as the difference in density may lead to the valve disc breaking easily. And there’s definitely no problem with the hydrogen valve diaphragm of the nitrogen valve, as the molecules become smaller. But the traffic has increased
I agree with you; the valve selection depends on the structure, gas flow rate, operating pressure, and operating temperature. It’s also necessary to assess the impact of changes in the valve’s operating temperature, so it’s better to turn to a professional manufacturer
