Wire mesh Demister Pad

Wire Mesh Demister Mist Eliminators Standard Specification

Demister Pad collect liquid particles accompanying airborne droplets in the vapor phase after boiling, vacuum evaporation or bubbling process. Droplets grow in size their weights become heavy so they are fall free. It is making clean products at the top.

2. Construction of wire mesh demister

A.The wire mesh demister shall be fabricated in one piece or in the minimum number of sections required for insertion through the vessel manway.
B.Mesh pads shall fit tightly into the pad containment system.
C.Mesh pad layers shall not be more than 9 inches (230 mm) thick. Where more than one layer is required, joints shall be staggered.
D.One-piece circular mesh pads may be spiral in form.
2.3Supports and Grids
A.The general arrangement of Mist Eliminator supports and grids shall be as factory habit unless required by customer.
B.Final details of Mist Eliminator supports and hold down grids can also be furnished by the Mist Eliminator supplier.
C.The Mist Eliminator supplier shall furnish details of components attached to the vessel to the vessel fabricator in time to permit installation without altering the vessel fabrication schedule.
D.Each section of the mesh pad shall include a grid on each side.
E.Style G mesh pads shall be furnished with an inlet and an outlet rigid welded grid. The outlet grid and blanket outlet zone of the Style G mesh pad shall be distinctly marked “Outlet”.
F.Spiral mesh pads shall include X-type grids on both sides.
2.4Fastening Devices
As the Mist Eliminator fabricator we can supply wire ties or other devices to fasten the Mist Eliminator sections to the supports, attach the grids to their vessel supports, and where multiple layer Mist Eliminators are necessary, to secure the layers together.

3. Demister mesh density and its applications

1.Mesh density(stainless steel) 50 kg/m3 Application: Heavy fouling, e.g. evaporators

2.Mesh density(stainless steel) 80 kg/m3 Application: Moderate fouling, e.g. vessel boilers

3.Mesh density(stainless steel) 110 kg/m3 Application: Light fouling

4.Mesh density(stainless steel) 145 kg/m3 Application: Heavy duty, e.g. oil and gas separators

5.Mesh density(stainless steel) 170 kg/m3 Application: General purpose, not totally clean

6.Mesh density(stainless steel) 195 kg/m3 Application: Optimum efficiency & pressure drop

7.Mesh density(stainless steel) 240 kg/m3 Application: High density with high separation efficiency

8.Mesh density(stainless steel) 112 kg/m3 Application: General purpose, clean service

9.Mesh density(stainless steel) 145 kg/m3 Application: Find droplet removal in clean service

4. Applications of demister pad

5.What can factory do for you in the wire mesh demister?

1. demister is tailor made to suit for specific vessel dimensions and configuration.
2. provides wide variety of material to suit for even the most corrosive process environments.
3. factory can supplies either mesh pad only, or complete demister with top and bottom supporting grids for direct installation in vessels.
4. Sectional construction for easy handling and access through man ways.
5. Complete accessory pack including support ring and beam can be provided when required.
