Major compressor upgrade job - replacing wet seals with dry gas seals. Project: Oil refinery at Angarsk Petrochemicals (Rosneft), Angarsk, Russia, 2009. The transfered gas is petroleum gas with high content of solids and heavier fractions condensate!

Old wet seal

This is the old wet seal. The compressor is horizontally split. The wet seal was part of the lubricating system so with the wet seal removed the lubrication system had to be modified.

test rig for dry gas seals

Dynamic test rig for dry gas seals. This test stand is used to dynamically test gas seals at conditions exceeding operating parameters of a compressor in both pressure (up to 100 bar) and rotor speed (up to 20,000 rpm). Two gas seals may be tested at the same time
