For an old process centrifugal compressor equiped with an isolation bladder inside the accumulator (API614 Figure 2A-14; 50 liter), the oil pressure does not correspond to the height of the liquid (4.5m). About 150mb is missing. The bladder is causing this anomaly; the existing bladder material...
A 4400 rpm high temperature steam turbine vibrates intermittently. The fouling/coking of the oil labyrinth is suspected as origin. If this is the case and after confirmation, it is possible to clean the deflector with the turbine in normal operation by means of a special high-pressure cleaner...
Would you use an axially or radially CC or integrally geared compressor containing 95% H2S and light hydrocarbons? Pressures barg in/out: 2 / 12. Power less than 1Mw. Dry gas seals. What would be your basic requirements?
