High Efficiency Coalescent Cyclone Separators

MKII KS Coalescent Cyclone Separator

Liquid droplets within the gas flow at both start up and during normal operation may cause the following problems.

  • Equipment damage due to erosion and/or corrosion.
  • Reduction in process efficiency due to lower heat transfer rates.
  • Increased maintenance and downtime.
  • Process contamination due to liquid carryover.
  • Impact damage to mechanical components.
  • Pipeline corrosion.

The Kelburn Engineering Coalescent Cyclone Separator both protects equipment and prevents the problems associated with liquid entrainment in gas or compressed air. The separator range has been proven in service world wide.

Liquid Droplets Coalescing Through 1st Stage Agglomerator

Cyclone Separator Operation

The Coalescent Cyclone Separator has a two stage separation design. The first stage agglomerates the fine liquid particles causing them to coalesce by bringing the droplets together, increasing their size and mass. The second stage then utilises profiled defector blading which imparts powerful centrifugal forces to separate all the liquid droplets from the gas flow. The liquid exits the separator from a volute contoured drain.

These highly efficient, flow driven separators remove all droplets down to 10 microns in size and 80 - 90% in the range 5 - 10 microns. The separator operates with overall extraction efficiencies of more than 99.5%.

The Kelburn Engineering separator generates a very low pressure drop, typically less than 1% of the system operating pressure.
