Nitrogen is compressed from 1 atm to 5 atm at 25°C; the temperature at the compressor outlet reaches 267°C. What’s wrong there?

In practice, it is unlikely for the compressor outlet temperature to exceed 150°C

The simulation result is 267°C, but in practice it is unlikely to exceed 150°C due to issues such as lubricating oil. I don’t know right now whether my Aspen simulation is correct or not.

In practice, do you increase the pressure from 1 bar to 5 bar? The pressure ratio here is 5!

You’re referring to the injective type, where the temperature inside drops; Aspen doesn’t take this into account

It’s not necessarily wrong in reality; without cooling, it’s possible

5 voltage ratio; the temperature is a bit high.

Check the pressure unit, or gauge pressure, etc
