Problem

Significant performance loss and high vibration on the Charge Gas 2/3 stage compressor was experienced one year following the 2003 Turnaround. This followed two consecutive, highly successful runs after application of antifoulant coating in 1995.

Summary

Performance loss and vibration was due to severe fouling. Severe fouling led to axial and radial rubs. Severe fouling was due to liquid carryover from suction drums. 2/3 stage compressor overhauled and returned to service Suction drum demisters upgraded to high efficiency.
