Reciprocating compressors

Design/Project Engineering & Execution Phase

  1. Technical feasibility study, bid review, selection, specifications.
  2. Thermodynamics design appraisals.
  3. Compressor-pulsation bottles-piping interaction design appraisals.
  4. Design review of piston rod dynamics (inertia and gas forces) for single and double-acting mechanisms.
  5. Crank shaft design and deflection appraisal.
  6. Torsional dynamics review.
  7. Review of hardware design & construction drawings with OEM engineers/experts.
  8. Compressor assembly inspection and shop testing.
  9. Electro-mechanical-thermodynamics control system design review.
  10. Design and off-design performance.
  11. Refurbishment/Upgrade studies.
  12. Foundation, Installation & Commissioning matters and performance examination during warrantee period.

Operational Phase

  1. Reliability & Mission time (extension studies).
  2. Performance gap/stretch studies.
  3. Crank-end/head-end pockets loading/unloading optimization (to shun pulsation generation).
  4. Reciprocating compressors malfunctions diagnosis and cure (valves dynamics, structural resonance, vibration, noise, pulsation/acoustic, thermal signature, thermodynamic performance etc.).
  5. Best practices of reciprocating compressors condition monitoring, operation and maintenance.
  6. Condition-based inspection & maintenance schemes and decisions.
  7. Crank shaft web deflection, anchor bolt stretch, foundation issues.
  8. Pro-active performance appraisals of key parameters during steady state/transient modes to capture faults at embryonic stage before they turn in to full-scale problem that may lead to un-plan interruption in production.
  9. Actual flow measurements and calculation.
  10. On/off-lines condition monitoring schemes and performance package development (running power & efficiency estimation).
  11. Root cause investigation of distressed component, failure and restoration (piston rider rings, valves, bearings, piston rod, crank-shaft, seals, casing distortion).
  12. Balancing reciprocating masses.
  13. Control systems problems.
  14. Review/improvement of compressor supervisory instrumentation.
  15. Alignment (hot/cold) and piping forces & moments.
  16. Life cycle cost & remaining life assessment.
