Compressor Performance Recovery

Corroded overhung compressor

Impeller 3D reconstruction

Flow rate recirculation

LocationItaly
ApplicationSulfuric Acid Production
Compressor TypeOverhung Centrifugal Compressor
ServiceCombustion Air
Power2.6 MW

Challenge

Performance loss (efficiency and flow rate) caused by increased clearance between impeller and casing due to corrosion

Solution

  • Labyrinth seal insertion
  • Clearance reduction

Result

+6% Volume flow rate, +1% efficiency
