Mist eliminators for liquid carryover control

PunchTech manufactures mist elimination systems for removing entrained liquid droplets from gas and vapor streams in process columns, separators, scrubbers and industrial vessels.

Solutions are reviewed against process conditions, droplet-separation requirements, allowable pressure drop and mechanical installation constraints.

Why Mist Elimination Matters

A controlled separation stage before the outlet

Liquid droplets carried within a gas or vapor stream can affect downstream process performance and equipment reliability.

A correctly selected mist elimination system provides a controlled separation stage before the gas or vapor exits the equipment.

Excessive carryover may contribute to

  • Product losses
  • Downstream contamination
  • Equipment loading
  • Process instability
  • Reduced separation effectiveness
Mist Elimination Solutions

Selected to the separation duty

Depending on the application and PunchTech's verified manufacturing range, solutions may include the following.

Wire Mesh Mist Eliminators

Knitted mesh elements provide a large contact area for entrained droplets to collect, coalesce and drain from the gas stream.

Vane-Type Mist Eliminators

Vane arrangements use changes in gas-flow direction to separate entrained droplets through inertial effects.

Custom Mist Elimination Assemblies

Application-specific arrangements may include:

  • Segmented elements
  • Support grids
  • Hold-down systems
  • Drainage details
  • Sealing arrangements
  • Custom supports

Available mist-eliminator configurations and performance data are confirmed against the approved process conditions and project specification.
