Knock-Out Drums

The Knock-Out Drum (KO Drum) purpose is to remove liquid droplets or mist from a gaseous stream. KO Drums have multiple applications. KO Drums are installed upstream of flare stacks, upstream of gas filters on gas transmission lines. Other applications are upstream of gas compressors, generators, engines or turbines.

TSI Fabrication is able to fulfill your KO Drum needs. For more details on KO Drum products or custom fabrication of this product line contact TSI Fabrication.

Applications:

  • Flaring process in flow back, production and pipe line cleanup operations
  • Natural transmission lines
  • Fuel scrubbers for compressors, generators, engines and turbines


Features and Benefits:

  • Minimum pressure drop across the knock-out drum
  • Removal efficiency of +99% for ≥5µm (micron)
  • Turn down ratio per requirement
  • Level gauges to monitor liquid accumulation
  • Ample liquid accumulation space
  • Inlet/Outlet tap option for differential pressure gauge
