Hei JJpellin, Please find the attached below.What will happen if you remove this "Permissive to start lube oil pump logic"? Regards Lahorihttps://files.engineering.com/getfile.aspx?folder=59ff088c-aae5-4aa9-852c-959bfd8e33e8&file=attachment.docx

Hi, can somebody please help me here. What does it mean " A permissive to start lube oil pumps ".Actually I am working with seal gas system and this logic is on pressure differential transmitter (PDT) for both at the inlet and out of the compressor barrier gas. Regards YB

Hi, I have a scenario in which seal gas is taken from 3rd impeller of centrifugal compressor. There are no pressure or temperature measurement on this take off. So if I need to find out the seal gas process conditions how should I calculate it. Regards Yasir

Hi Johnny, Thanks for your reply. What is the reason behind to balance both seal chambers to the same the pressure. Regards Yasir

Hi, I am working on a Dry Gas Seal Project for Centrifugal compressor. I have a book on Compressor Dry Gas Seal 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 the...

Hello, I am working with Centrifugal compressor gas seal system. Seal are of Dry Gas type. I can see a Balance line on the P&ID of seal system. Can anybody please explain what is the purpose of this balance line? Regards Yasir

Hi, Thanks for taking out time to reply. Actually i am working with Dry Gas seals. The arrangement of seals are of tandem type.Over the years Seals are failing because of leakage. So i need to find out the leakage rate through process labyrinth. I have checked the book you suggested but it does...

Hello , Currently I am working with Centrifugal compressor seal gas system, .It is an existing system and I need to find the leakage rate through the labyrinth. Can somebody please guide me where can I find " Egli, A. 1935. The leakage of steam through labyrinth seals. Transactions of ASME...
