Alloy 20 Material Wire Mesh Mist Eliminator And Other Options
HL-130
The Cr content of alloy 20 (n08020) nickel base alloy is usually 19.0% - 21.0%, and the nickel content
is 32.0% - 38.0%. Alloy 20 (incoloy20) is a nickel base alloy with molybdenum and copper, which has good
hot and cold working properties. Alloy 20 (n08020) nickel base
alloy is a corrosion-resistant alloy with many excellent
properties. It has good resistance to oxidation and medium
reduction corrosion, excellent resistance to stress corrosion
cracking and good resistance to local corrosion. It has
satisfactory corrosion-resistant characteristics in many chemical
process media.

When properly designed demister pads can give efficiency up to
99.9% with minimal pressure drop. Normally demister pads can remove
droplets down to 5 microns and lower with a free volume of up to
99% and a surface area of up to 1940 m2/m3. Due to high value of
free volume the pressure drop across the demister pad is
sufficiently low in most applications.
When wire mesh mist eliminator should be replaced?
Due to the fact that the mesh pad demister is normally installed in
a major process line, it is almost impossible to replace them while
the lines are in operation. Therefore, for economy purpose, it is
important to have them replaced during annual or periodic shut-down
period. For these reasons, the followings are presented for the
user’s consideration.
When the thickness has changed.
When the tightness of each pad sections has changed.
When the corrosion of the wire is severely noticed.
When the entrained mist or dust gives pressure drop hazard.
Others as having been experienced by maintenance engineers.
