High Capacity Packed Column Internals For Vane Pack Mist Eliminators

Vane Pack Mist Eliminators are high capacity separators; they collect essentially 100% of all particles greater than 8 to 40 microns in diameter, depending on design parameters. They are assembled as banks of parallel vane profiles. This design causes the gas to change direction a number of times from inlet to outlet of the separator. The intertia of the liquid droplets forces the entrained liquid droplets to impinge on the vane surfaces where they form a liquid film and drain. Simple Vane Pack profiles are particularly suitable for applications with a significant risk of fouling due to solid particles or high viscosity liquids in the feed. It offers a wide range of Vane Packs depending on the direction of gas flow and the complexity of the vane profiles. Sectional installation of the vane banks allows installation and removal through the vessel manway.
Complex Vane Pack designs provide special separation channels to allow disengagement of liquid and drainage from the vane surface which increases the capacity. These profiles are therefore used when equipment size is critical,
for example in de-bottlenecking of existing equipment.
