E-LNG - Compressor - Saudi Arabia8-impeller barrel-type propane compressor STC-SV 14-8-A with one sidestream
and nozzles upwards for a gas plant in Saudi Arabia. Impeller diameter is 950 mm.
Discharge pressure is 24 bar at a driver power of 19 MW. Siemens has built barreltype
compressors of this size for discharge pressures of up to 90 bar. Such barrel-type
compressors are used as high-pressure casings for mixed-components refrigerant
compressors in LNG plants. |
