Can a dry ai screw compressor be used for compressing nitrogen?

[mechanicaljw]

Hi All,

I have searched the forum to see if i would get an answer to my question to no avail. I am therefore posting the question here:

Would it be possible to use a dry screw compressor that compresses air from atmospheric to 3.5 bar(a) for compressing nitrogen and get the same compression without making any modification to the screw rotors or the compressor design?

The reason is because the process needs pure nitrogen.

Thank you in advance for your response.

There are nitrogen generators

Depending on how much you need, what about a liquid nitrogen tank and vaporizer?

Yes, you can, physical properties of dry N2 are similar to those for air.
