Reciprocating Compressors

5 days MTE/EECV-E
  • Engineers and technical staff involved in the operation, inspection and maintenance of reciprocating compressors.
  • To improve participants skills in mastering the operation of reciprocating compressors.
Learning Objectives
  • To identify the different process and auxiliary circuits, the different parts of a compressor and explain their role.
  • To explain the evolution of compressor operating parameters.
  • To implement appropriate monitoring for every specific compressor.
  • To be involved in troubleshooting activities.
  • To communicate efficiently with staff from other departments.
Ways and means
  • Actual examples from the upstream, refining, petrochemical and chemical industries.
  • Trainee participation is continuously encouraged through case studies selected by the lecturer or proposed by the trainees themselves.
  • Using a dynamic simulator to illustrate phases of start-up, shutdown, including some upsets generated by the instructor.

Technology 1.5 days
  • Construction and design philosophies.
  • Components of reciprocating compressors: frame, cylinders, piston and rings, piston rod and crank head, crankshaft and connecting rods, bearings, compartment distance piece, specific emphasis on valves.
