Hydrogen compressor operating on nitrogen
Thread Content
Can the hydrogen-blended compressors produced by German company Normann be operated with nitrogen? ? Experts, please explain the reasons. . . . Thank you. . .
You need to recalculate based on the nitrogen temperature, pressure, and molecular weight, in accordance with the design standards for hydrogen mixing compressors, to determine whether it is possible to use nitrogen, as well as the operating flow rate and outlet pressure parameters.
Can’t it be decided by someone other than us? In situations like this, there are many factors to consider; what was said above is quite correct. It’s not enough to just look at temperature and pressure – the average molecular weight also needs to be taken into account. A feasibility study is necessary, and it would be best to consult a research institution for this purpose. Once a performance curve can be drawn, things will become much simpler!
Hydrogen compressors can be operated with nitrogen, but certain conditions must be met. Firstly, all components of the hydrogen compressor are designed for use with hydrogen as the working medium; if it is operated using nitrogen, numerous problems will arise, such as an increase in exhaust temperature and increased load, which can lead to damage to the machine’s components. The valves are the most susceptible to damage in such situations. Of course, if you need to conduct tests using nitrogen, manufacturers generally provide the operating conditions for using nitrogen; in such cases, the pressure will be much lower than the operating pressure. Another option is to purchase a nitrogen valve (a valve designed for use with nitrogen). This post was last edited by rmxg on 2009-4-10 18:01]
Operating with nitrogen is definitely possible. However, it is necessary to ask the manufacturer for the operating parameters; one cannot rely solely on their own understanding. If nitrogen is used, the pressure must definitely be lower than the normal hydrogen mixture pressure. . . . . . . . .
