Can a nitrogen valve be used to deliver hydrogen?
Thread Content
What are the consequences of using a nitrogen valve to introduce hydrogen into a compressor?
Keeping temperature rise and pressure under control won’t pose any danger!
Do not use a nitrogen valve to supply hydrogen; pay attention to the motor current and exhaust temperature
Nitrogen valves of the same size have a larger flow area compared to hydrogen valves; it is possible to use nitrogen valves in place of hydrogen valves without any problems, and this has little impact on exhaust temperature and pressure. However, there will be a greater power loss.
They cannot be used interchangeably; I’ve encountered such cases before. I think it was nitrogen and hydrogen – their densities are different, so the gas valves cannot be used together
It has little impact on the air valve itself; the main thing is to ensure that pressure and flow do not exceed specified limits, and to be careful that the motor power is not overloaded.
At the same pressure and inlet temperature, the high-temperature resistance of nitrogen gas valve designs is greater than that of hydrogen gas valves, resulting in higher costs； It is possible to inject hydrogen.
