2. Features
Wire Mesh Demister
Wire mesh mist eliminator also known as wire mesh demister, is a
kind of vapor liquid separating device.It is made up of many
corrugated gas liquid filter net,a grid and a fixed distance rod
.It is most often used to separate liquid drop with diameter of
more than 3-5 μm in the separation tower.It can ensure the mass
transfer efficiency,reduce the loss of valuable materials after
operation of compressor, commonly setted in the top of device.It is
widely used in gas-liquid separation in chemical, petroleum,
sulfate, medicine, light industry, metallurgy,
machine,building,construction, aviation, shipping and environment
protection.
Size and structure can be customized according to customer's
drawings.
Wire Mesh demister pad is a kind of vapor-liquid separating
device,constructed by knitted wire meshand metal frame,mainly used
to separate drops of the diameter between 3μm to 5μm. It is
widelyused in the chemical,petroleum,medical,light,metallurgy and
environmental protection industries.

4. Material Comparison about Tower internals Stainless steel Wire
mesh demister pad for gas-liquid filters
Difference between duplex 2205 stainless steel plate and Austenitic
304 stainless steel plate
1) The yield strength of austenitic stainless steel is more than
twice as high as that of ordinary austenitic stainless steel
Enough plastic toughness. The wall thickness of the tank or
pressure vessel made of duplex stainless steel is 30-50% less than
that of austenite, which is helpful to reduce the cost.
2) Even duplex stainless steel with the lowest alloy content has a
higher ability of stress corrosion cracking resistance than
austenitic stainless steel, especially in chloride containing
environment. Stress corrosion is an outstanding problem difficult
to solve for normal austenitic stainless steel.
3) The corrosion resistance of 2205 duplex stainless steel, which
is widely used in many media, is better than that of 316L
austenitic stainless steel, while super duplex stainless steel has
very high corrosion resistance. In some media, such as acetic acid,
formic acid, etc., it can even replace high alloy austenitic
stainless steel and even corrosion resistant alloy.
4) Compared with austenitic stainless steel with the same alloy
content, it has better wear resistance and fatigue corrosion
resistance than austenitic stainless steel.
5) Compared with austenitic stainless steel, the coefficient of
linear expansion is lower, close to carbon steel, suitable for
connection with carbon steel, which has important engineering
significance, such as production of composite plates or linings.
6) No matter in the condition of dynamic or static load, it has
higher energy absorption capacity than austenitic stainless steel,
which has obvious advantages and practical application value for
structural members to deal with sudden accidents such as collision,
explosion, etc.
5. Advantages:
High removal efficiency
Negligible pressure drop, less than 25mm of water gauge
No maintenance or service required
No corrosion or temperature limitations
Easily installed in existing vessels
No limitation on size or shape.
