Liquid found in DGS strip down

Hi there,

Never good to find liquid in a dry gas seal, but something we have definitely seen before!
Few immediate causes of liquids in dry gas seals can be:
– Seal Gas is flowing with free liquids,
– Seal Gas is insufficiently filtered,
– Seal Gas is insufficient temperature to remain above dew point from pressure drop over seal faces,
– Reverse flow from compressor case across labyrinth seals.

If you can check the above and feedback some data then that would be great! Data/trends on temperatures of seal gas, gas analysis for dew-point and compressor pressures / setup are a good start. Also a seal gas schematic for review.

Interesting topic we can definitely assist with!
