Where a relatively low efficiency is acceptable, or where a higher pressure drop can be allowed, “hook type” Vane Type demisters (or “vane packs”) may be utilised. These offer the client a commercial advantage due to their simple and robust design, and extremely low maintenance costs.

The ZP-110 Vane Type Demisting Device offered by Zeta-pdm Ltd can be utilised in both horizontal and vertical separators. It provides a high drainage capacity and is self-cleaning during operation.

The ZP-110 Device incorporates "hooks" that protrude within the main gas stream, perpendicular to the gas flow and extending across the full height of the vane pack. After running into the liquid collector, the liquids are drained into the bulk liquid within the separator, returning to a level below the lowest liquid level, i.e. below the Low Low Liquid Level (LLLL), via a liquid "downcomer" system.

Advantages of the ZP-110 Vane Type Demisting Device:

  • Offers a gas / liquid separation efficiency in the medium range
  • Low re-entrainment
  • Able to handles high liquid loading
  • Robust construction
  • Low installed cost
  • Easy to install in both new and existing separators
  • No moving parts, so no maintenance.
