The vane types are very usual and useful internals for liquid
separation from gas. These types according to design and shape
can remove the droplets more than 8 microns.
The mist droplets, which are separated by the resulting
centrifugal forces, collect on the vane blades. This coalesced
liquid film is then drained through slits or pockets to a liquid
sump from where it drains to the liquid compartment of the
vessel.
