seal oil leakage on centrifugal compressor
seal oil leakage on centrifugal compressor
(OP)
We have a two 2 MW natural gas feed centrifugal compressor barrel type that is still equipped with a seal oil system. Upgrade to dry gas seal is foreseen but not immediately.
We are currently experiencing leakage and seal oil coming out of the vent both on the seal assembly as well as on the vent coming out of the seal oil tank.
It seems the seal oil tank pressure is increasing abnormally but not completely sure.
Any idea of what can be at the root of this? The seal oil system and lube oil system are separate.
Thanks in advance for any orientation.

If there is a flame arrestor on the tank, have it cleaned and inspected.

Thanks for the input, I will revert seal configuration asap.

As suggested, the current tank vent should be routed to flare or to some safe location with a flame arrestor or similar.
