Rich gas compressor leak, dry gas seal at 0.4 MPa

What is the current sealing pressure difference? As long as it is not lower than 100 kPa, there should be no problem. Is there some odor because of a leak in another area?
Switch to nitrogen sealing, or use both simultaneously
Maybe there's a leak in another area? Use a combustible gas detector to find the area with the highest concentration!
Reply to 2# i-play: What’s leaking is the enriched gas; the sealing isn’t good. Now that the nitrogen pressure has increased, things are much better
Reply to 3# Zhang Junmeng: We use nitrogen
Reply to 4# Snow removal at the north gate: it was due to a leak in the pressure pump and poor nitrogen sealing; now that the pressure has been increased, things are much better
A dry gas seal at 0.4 MPa is quite good; it shouldn’t leak, right? I’m also wondering if it’s something else causing the issue
One method is to use additional liquid nitrogen to increase the nitrogen pressure, while the other is to increase the speed of the gas turbine in order to reduce the pressure of the enriched gas; as long as the sealing pressure difference remains above 1 kilogram, that’s sufficient
