Screw Compressor Replacement in PP Unit (Post-Failure Replacement)

1. Project Overview

• Industry: Petrochemical

• Application: Polypropylene (PP) Unit

• Original Equipment: VML95

• Replacement Model: CS100L

• Operating Condition: 2.0 bar / Continuous Operation

• Date: 2022

2. Project Background

The client operates a polypropylene (PP) production unit where the original VML95 compressor had been previously repaired.

Due to insufficient understanding of internal technical requirements during maintenance, the repair resulted in performance degradation and internal damage, leading to reduced efficiency and reliability.

3. Challenges

• Equipment damage after improper maintenance

• Reduced performance after repair

• High cost of original spare parts

• Uncertain long-term reliability

• Need for stable replacement solution

4. Our Solution

Procetek provided a CS100L oil-free screw compressor as a replacement:

• Fully matched original installation and system design

• Delivered consistent and stable operating performance

• Enabled seamless replacement with high compatibility

• Provided a cost-effective alternative solution

5. Scope of Supply

• Oil-free screw compressor

• Procetek Model: CS100L

8. Results

• Maintenance cost reduced by 30–50% 

• Improved system stability

• Reliable long-term operation

• Reduced dependency on high-cost spare parts

9. Why It Worked

• High compatibility with existing system

• Reliable design and performance

• Strong understanding of compressor operation and failure modes

• Proven replacement engineering capability

10. Conclusion

This project demonstrates the importance of proper replacement after equipment damage, ensuring long-term stability and cost control.
