Wire mesh demister,knitted wire demister pad,demister pad
A demister, or also known as mist eliminator, is a high efficiency
separation device often fitted to vapor liquid separator vessels to
enhance the removal of liquid droplets entrained in a gas or vapor
stream. Demisters may be a mesh type coalescer, vane pack or other
structure intended to aggregate the mist into droplets that are
heavy enough to separate from the vapor stream.
Mist eliminators/ demisters are fabricated from knitted materials
with interlocking asymmetrical loops of metal or plastic with
typical diameters being 0.1 – 0.3mm. Special applications for wire
diameter 0.35mm to 0.024mm, tube width 1/4" to 42" diameter.
Stainless Steel wire: 200, 300 and 400
Copper wire, Aluminium wire, Nickle wire, Titanium wire, Inconel,
Monel, Hastelloy wire...
Plain Steel, Galvanized Steel...
Polypropylene, Polyethylene, PVC, Teflon(PTFE), Nylon, etc.
Stainless steel wire with cotton thread, fiber glass, etc.
The demister should be horizontally fixed and supported. At the
bottom or both the top and the bottom, a support grid which is
welded with FB 25X3t, RB6Ø of the same material as that of the
demister pad at proper intervals (APP150mm), is used. For fixing
the grid and the pad, RB6Ø or 1.6Ø tie wire is used. The way of
fixing is as per the below figure.
4.DEMISTER FEATURES (Mesh Pad type)
1).It shows 99% efficiency under general conditions and velocity
(1~3m/sec or higher).
2). Over 98% open area is guaranteed under any conditions so
pressure drop caused by the use of the demister can be disregarded
3). It can be made of any material suitable for the given
temperature and corrosion-resistance.
4). It is possible to install by use of M/H so it is easy to
5). There is no restriction in the conditions, place, and size for
use. It is install-able on the existing systems.
6). Self-cleaning is possible. It is semi-permanent so it is
5.USE OF DEMISTER
1).Vacuum Tower - The treatment quantity by the demister goes up by
35%. The quality of oil gas is improved.
2). Absorber - Some gasoline plants use a glycol absorber (Demister
mounted) so the installation cost is being repaid within a month.
3). Knockout Drums and Separators - If Demister is used, ⅓inch drum
4). Gas Separator Vessels - Hydrocarbon in gases is collected so
gas of 1/0.1 billion purity is produced out.
5). Evaporator - Product loss goes down and purity is remarkably
6). Scrubber - In the field of caustic soda, the demister is used
to prevent air pollution.
7). Distillation Column - If Demister is used, the cost for
distillation goes up, the quantity of treatment increases by 20%,
and purity is remarkably improved.
8). Dust Collectors - The dust collector of a wet type has
excellent collection capacity.g is possible. It is semi-permanent
so it is economical.
