PP plate mist eliminator / vane pack demister / chevron mist
eliminator / droplet separator
The vane types are the Chevron type of mist eliminators which
consist of a set of specially designed vanes with a well defined
geometry, with closely spaced corrugated plates. They 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.
Hualai has produced a range of mist eliminators for critical
applications in the oil and gas sector, Standard Material of vane
type mist eliminator is polypropylene & stainless steel.
Basically, we can produce and supply two vane height types, 170mm
and 235mm, in both PP and stainless steel material. No problem for
any shape and size.
| vane shape | Material | Hook (yes/no) | Vane Height | Total Height (with frame) |
| Streamline | PP | yes | 170mm | Appr. 200mm |
| PP | yes | 235mm | Appr. 250mm |
| PP | no | 170mm | Appr. 200mm |
| PP | no | 235mm | Appr. 250mm |
| poly-line | PP | no | 170mm | Appr. 200mm |
| PP | no | 235mm | Appr. 250mm |
| SS | no | 170mm | Appr. 200mm |
| SS | no | 235mm | Appr. 250mm |
When to use vane type mist eliminator instead of mesh pad?
Larger droplets;
High Gas Velocity;
Low Pressure Drop;
High Liquid Load;
Extremely Viscous Liquid;
Accumulated Residues;
Clogging Particulates;
Severe Corrosion;
Surge Buffeting;
Foam Problems
I have a customer from South East Asia, who is in the vessel repair
and service business. Early this year Mr. K enquired to us
for a kind of vane plate mist eliminator to be used in ventilation
system of vessels. It had limited space for the vessel and
nominated gas flow direction, which was different from our normal
intallation way. I listened to Mr. K carefully and made the draft
drawing below for his checking. I took both the gas flow direction
and space into consideration. Meanwhile I checked with our workers
beforehand to see if they could realize my design with our raw
material. After friendly communication, everything was settled and
the order went into production soon.
Hualai vane plate mist eliminator allows inlet air to turn and pass
between the profiles with minimum restriction. Drops impact the
profile surface where they are collected and drained.
I expect to be helpful in your special projects, too.
Vane type eliminator is mainly used for flue gas desulfurization
and separation of mist droplets in tail gas. It has the advantages
of simple structure, high capture efficiency for medium size and
large size mist droplets, low pressure drop, easy flushing, open
structure, easy maintenance and low cost.
Removal of very small droplets can be achieved using a two stage
mist eliminator by fitting a mesh pad to the upstream face of the
unit to coalesce droplets as small as 4 to 5 microns into droplets
in the size range which are easily removed by the vane separator.
