Buffer Gas Spec.
Buffer Gas Spec.
(OP)
Dear Eng-Tip'ers,
I have a plan to change the buffer gas media for centrifugal compressor from pure H2 with 99.9% purity to H2 rich gas with purity between 92 % - 97 % but I dont have any clue whether the shifting will be OK or not. Does anyone has information on the specification or requirement for centrifugal compressor's buffer gas?
Thanks for your help.

RE: Buffer Gas Spec.
Because when you say buffer gas, it means you have different supplies for seal gas supply and separation gas supply in addition to the buffer gas supply.

If you are using gas seals, then I would try to dissuade you from switching to a less pure buffer gas.
If your talking about buffer gas injection "inboard" of the seals, then a low quality gas may do.
