Screw Compressor Replacement in Pneumatic Conveying System

1. Project Overview

• Industry: Petrochemical

• Application: Pneumatic Conveying System

• Original Equipment: VML60

• Replacement Model: CS70L

• Condition: 2.0 bar / Variable Load

• Date: 2025

2. Project Background

The client operates a pneumatic conveying system in a petrochemical plant. The original compressor was designed for higher operating parameters than actual working conditions.

Over time, the mismatch between design and real operation led to increased failure rates and unstable performance.

3. Challenges

• Actual operating conditions lower than design parameters

• Frequent operational instability

• Increased failure rate

• No standby compressor available

• Risk of system interruption

4. Our Solution

Procetek provided a CS70L oil-free screw compressor optimized for real operating conditions:

• Matched actual flow and pressure requirements

• Improved efficiency under partial load

• Direct replacement without system modification

• Enhanced system stability

5. Scope of Supply

• Oil-free screw compressor

• Procetek Model: CS70L

Speed (rpm)	9823	9823

7. Installation & Site Photos

Before Replacement

After Replacement

• CS70L compressor installed

• System operating under real conditions

Compared to the original unit, the replacement improved stability by matching actual operating conditions rather than theoretical design values.

8. Results

• Reduced failure rate

• Improved system stability

• Better adaptation to real operating conditions

• Reliable long-term operation

9. Why It Worked

• Application-based design approach

• Accurate matching to real conditions

• System-level optimization capability

10. Conclusion

This project demonstrates the importance of matching equipment to actual operating conditions, not just design specifications.
