The carbon dioxide (CO2) compressor is one of the key major equipment in a urea production plant that produces fertilizers. The compressor is normally a between-bearings, single-shaft centrifugal compressor design based on API 617.1 Without the compressor, plant production would be stopped. FIG. 1 shows a typical CO2 compression process in a urea plant, including a steam turbine, low-pressure casing, gearbox and high-pressure casing with suction knockout drum, inter-stages piping, coolers, reactor and separators.
