VM140 Compressor Severe Contamination & Performance Recovery

1. Project Overview

• Industry: Petrochemical

• Equipment: VM140 Screw Compressor

• Service Type: Repair / Deep Refurbishment

• Year: 2025

2. Project Background

The VM140 compressor was used in a petrochemical process and showed severe performance degradation during operation.

Inspection revealed abnormal conditions at the discharge side, indicating internal contamination and wear.

3. Problem / Failure Analysis

• Visible corrosion and contamination on rotor surface

• Material adhesion inside compressor

• Reduced efficiency and unstable operation

• Risk of progressive internal damage

4. Root Cause

• Harsh process conditions

• Accumulation of process materials

• Insufficient cleaning and maintenance

• Long-term operation without internal inspection

5. Our Solution

Procetek implemented a deep refurbishment and cleaning solution:

• Complete disassembly of compressor

• Removal of contaminants and deposits

• Cleaning of rotor and internal chambers

• Restoration of internal clearances

• Reassembly with precision control

• Performance testing under simulated conditions

6. Scope of Work

• Fault diagnosis and inspection

• Deep cleaning of internal components

• Clearance restoration

• Reassembly and testing

7. Before & After Condition

Before Repair

• Contaminated rotor surface and internal adhesion

During Repair

Internal cleaning and inspection process

After Repair

• Cleaned and reassembled compressor

After refurbishment, the compressor recovered stable operation and improved efficiency.

8. Results

• Restored compressor performance

• Improved operational stability

• Reduced risk of future failure

• Extended service life

9. Why It Worked

• Accurate identification of contamination issues

• Professional cleaning and restoration process

• Strong understanding of petrochemical operating conditions

10. Conclusion

This case demonstrates that deep refurbishment can effectively recover performance in severely contaminated compressors, avoiding premature replacement.
