Hi,
I am working on a dry gas seal project. I have a book on dry gas seals in which following is written.
" It is also desirable to minimize seal gas consumption. The majority of the injected seal gas flows across the inner labyrinth seal and back into compressor (the flow is recycled)."
Now here author is talking about after passing through inner labyrinth seal and back to compressor. I cannot understand this one. In my understanding as seal gas is injected it flows through primary seal and then to primary vent.
I am still very much new to the topic so may be I still do not have full grasp of the topic. Please help me out here.
Regards
Yasir
