Inline Vane Separator AVS

Design Advantages

The Anderson Pocket Type Vane has several advantages over our competition’s Hook-Type Vanes.

  • Anderson Vanes have a shielded pocket for uninterrupted liquid collection and drainage.  The draining liquid is protected from re-entrainment and thus able to handle an increased volume.

  • Anderson Vanes have a lower pressure drop with increased capacity as compared to Hook-Type Vanes.

  • Anderson Vanes provide a more laminar flow with lower turbulence due to advanced flow profile design.

  • Anderson Vane Bundles are smaller in size compared to Hook-Type Vanes in similar applications.  This results in a smaller more efficient and economical vessel design.

Principal of Operation

The success of the Anderson Separation Vane is rooted in simple physics principles of centrifugal force, impingement and gravity.  The liquid laden gas entering the vane separator is a mixture of low-density gas and high-density liquid.  As this mixture passes through the van bundle, it is forced to change directions several times.  The low-density gas can easily negotiate this tortuous path, but because of momentum, the high-density liquid is unable to change direction without impinging upon the vane wall.

At each change in direction, a centrifugal force is imparted on the gas liquid mixture, which throws the liquid particles against the wetted vane walls.  These liquid droplets coalesce into larger particles, absorb other droplets striking the vane, convert to sheet flow and travel towards the vane pockets.  Once the liquid enters the vane pockets, they are isolated from the gas stream, and drain by gravity into the liquid sump.


Anderson Vane Separators will remove 100% of all liquid particles 8.0 microns and larger when operating between 0 and 110% design flowrate.  When operating at the design flowrate, a separation efficiency of 100% of 5.0 microns and larger is expected.

The Separation efficiency can be improved to 100% of 3.0 microns by the addition of an inlet coalescer. Separation efficiency decreases on droplets of decreasing size.  In order to separate these smaller droplets, the vane bundle must be preceded by an inlet coalescer.  The coalescer will increase the size of incoming liquid droplets so that they can be removed by the separation vanes.  The inlet coalescer can either be a special hookless vane bundle located in the inlet nozzle, or a stainless steel wire mesh pad mounted on the vane face.
