Case StudyAn ethylene compressor experienced a dry-gas-seal (DGS) hang-up condition and a RCA concluded that a possible root- or contributing cause is lube oil passing the labyrinth type separation seal into the secondary DGS cavity, causing the dynamic O-ring to malfunction. Detailed modeling and design review of the separation seal system enabled the investigators to postulate several scenarios to explain how lube oil could migrate into the DGS. The presentation presents a procedure how to calculate the exit velocities of labyrinth type separation seals and the effects of changes in various design parameters
