The flow rate of the primary seal gas for the turbine’s dry gas seal cannot be maintained and keeps dropping gradually

The flow rate of the primary leakage gas is high now
The turbine does not have a dry gas seal; the dry gas seal is used in your compressors. Please check your primary seal gas filter carefully. It is possible that there is liquid inside. It affected the effectiveness of the secondary seal
It’s likely that the sealing gas is too dirty – containing liquid or water – or that there isn’t enough of this gas, which leads to severe wear of the sealing surface.
With flow rate and pressure, if the flow rate is high, the pressure will definitely increase as well. Go and observe for yourself
Is the primary sealing gas made of process gas or nitrogen? What is the medium used for the process gas?
In hydrogen-related systems, the dry gas seal requires regular drainage as liquid accumulation in hydrogen is a serious issue; it’s advisable to install electric heating for the dry gas seal disk. It’s also necessary to monitor the trends and analyze the root cause of the problem
Circulating hydrogen entrains ammonium salt crystals, blocking the pipeline
There is a problem with the compressor’s seal disk, usually caused by liquid in the primary seal gas. It is advisable to replace the filter element in the liquid removal tank for the sealing gas.
The amount of gas used for the secondary seal isn’t adjusted properly; it is the gas intended for the secondary seal that is leaking from the primary seal
