For the dry gas seal of the catalytic enriched gas compressor, we use nitrogen seals
Thread Content
Has nitrogen entered the interior of the compressor housing?
As long as the process medium is used for the main seal, there is no problem.
The pre-seal air enters the interior of the unit, while part of the main seal air is partially evacuated
Some of the nitrogen entered the rich gas, while some was vented!

Personally, I think it’s better to take things slowly; it took me quite some time to figure this out, to understand each aspect one by one! What others say may not necessarily be easily accepted; only what one understands oneself can be remembered better!
The balance tubes are divided into primary balance tubes and secondary balance tubes. The function of the primary balance tube is to prevent leakage of medium from the first comb seal on the high-pressure side into the low-pressure inlet, while the secondary balance tube balances the pressure in the cavity between the comb seals on the drive side and the non-drive side as well as the main seals, thereby balancing the air flow rates of the two main seals
