Centrifugal Compressors

5 days MTE/ECC-E
  • Operation and technical department staff involved in operation, monitoring and maintenance of centrifugal compressors.
  • This course emphasizes the technology, the performance and operation of centrifugal compressors.
Learning Objectives
  • Upon completion of the course, participants will be able to:
  • describe the technology of centrifugal compressors,
  • explain operating conditions & main disturbances,
  • be involved in troubleshooting analyses.
  • No prerequisites for this course.
Ways and means
  • Case studies based on industrial feedback.
  • Various technical drawings of actual compressors.
  • Use of a dynamic process simulator.

TECHNOLOGY 1.25 days
  • Different types of centrifugal compressors. Architecture of a centrifugal compressor.
  • Technology of the main components: stator, rotor, bearings, thrust bearing, seals.
  • Vibrations, critical speed, dynamic balancing. Auxiliary equipment: lubrication system, buffer gas, balancing line, etc.
  • Safety devices: axial displacement, vibrations, bearing and thrust bearing temperatures, oil pressure, etc.
  • Changes in gas velocity & pressure in a centrifugal compressor.
  • Mass and volume flow rate as a function of pressure, temperature and gas composition.
  • Discharge temperature, power absorbed as a function of the gas composition and the operating conditions.
  • Compressor performance: influence of process parameters, impeller velocity and geometry.
  • Characteristic curves of the circuit and the compressor. Influence of the operating conditions: intake pressure and temperature, nature of the gas, rotation speed.
  • Flow rate control. Adaptation to service conditions.
  • Surge and antisurge devices. Conventional control. Start-up and shutdown.
  • Monitoring the compressor and auxiliary equipment under normal operating conditions. Troubleshooting.
DYNAMIC SIMULATION (IndissPlus by RSI) 1.5 days
  • Use of a dynamic process simulator.
  • Exercises on start-up & shutdown phases.
  • Applications using disturbances generated by the lecturer.
