Centrifugal Compressors

5 days MTE/ECC-E
  • Operation and technical department staff involved in the running and maintenance of centrifugal compressors.
  • To provide a broader understanding of the technology, performance and operation of centrifugal compressors.
Learning Objectives
  • To describe the technology of centrifugal compressors.
  • To select adequate operating conditions.
  • To explain the main operating problems.
  • To be involved in a troubleshooting process.
Ways and means
  • Case studies based on industrial feedback.
  • Various illustrations of actual systems.
  • Use of a dynamic simulator.

Technology 1.25 days
  • Different types of centrifugal compressors.
  • Component parts and architecture of a centrifugal compressor.
  • Technology of the essential 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.
Performance 1.75 days
  • Changes in gas velocity and pressure in a centrifugal compressor.
  • Mass and volume flow rate as a function of pressure, temperature and the nature of the gas.
  • Discharge temperature, power absorbed as a function of the nature of the gas and the operating conditions.
  • Compressor performance: influence of process parameters, impeller velocity and geometry.
