2500mm Plastic PTFE Demister Mat


Demister Mat 25*3mm Flat Bar

Product Description

2500 mm Custom Order 8 Parts Plastic PTFE Knitting Mesh Demister Pad



1. PTFE Knitting Mesh Demister Pad Description :


(1) A vapor stream carrying entrained liquid droplets passes through a demister pad. The vapor moves freely through the knitted mesh.


(2) The inertia of the droplets causes them to contact the wire surfaces and coalesce.


(3) The large, coalesced droplets formed in the mesh ultimately drain and drop to the vessel bottom


2. PTFE Knitting Mesh Demister Pad Application:


Knockout drums and separators ,Absorbers ,Scrubbers,Distillation columns,Evaporators,High pressure steam systems ,Refinery towers


3. PTFE Knitting Mesh Demister Pad Specification :


(1): General


1.1 Scope


A: This Standard Specification covers the general requirements for design, construction, fabrication, and material of Mist Eliminators specified in XXX Project Specifications.


B: Exceptions or variations shown in the Project Specifications take precedence over requirements shown herein.


1.2 References


Unless noted below, use the edition and addenda of each referenced document current on the date of this Standard Specification. When a referenced document incorporates another document, use the edition of that document required by the referenced document.


A: American Society for Testing and Materials (ASTM) A-478, Specification for Chromium-Nickel Stainless and Heat-Resisting Steel Weaving and Knitting Wire.


B: ASTM B-164, Specification for Nickel-Copper Alloy Rod, Bar, and Wire.


(2): Design


2.1 General


A: Size, style, thickness, configuration, and materials are specified in XXX Project Specification – Vessels.


B: Mist Eliminator styles are defined as follows:


Style Material


lb/ft3 (kg/m3)

Wire Diameter

Inches (mm)

A Metallic 9 (144.2) 0.011 (0.28)
B Metallic 5 (80.1) 0.011 (0.28)
C Metallic 12 (192.2) 0.011 (0.28)



normal 0.012 (0.30)
F Polypropylene normal 0.012 (0.30)
G Metallic


5 (80.1) - 9 (144.2)

0.011 (0.28)
V Metallic Other normal


C: Style G is a mesh blanket having a variable knitted density. The vapor inlet section is the least dense and the outlet section the densest. Typical inlet/outlet knitted mesh densities are 5 lb/ft3 (80.1) and 9 lb/ft3 (144.2). The customer can require variable density blankets having slightly different knitted densities and wire diameters.


D: Style V is to be determined by the vendor, based on the process conditions provided by customer. Vendor may determine the mist eliminator type best suited to meet the mist elimination requirement. The selected style may include a mesh pad, vane or a combination of mesh & vanes. The mist eliminator may be oriented vertically, horizontally or at an angle determined by the vendor. A single pad of variable knitted density may also be applied.


2.2 Construction


A: Mist Eliminators shall be fabricated in one piece or in the minimum number of sections required for insertion through the vessel manway.

Mesh pads shall fit tightly into the pad containment system.


B: Mesh pad layers shall not be more than 9 inches (230 mm) thick. Where more than one layer is required, joints shall be staggered.

One-piece circular mesh pads may be spiral in form.


2.3 Supports 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.


2.4 Fastening 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). Materials


3.1 Metallic Mesh Pads


Materials for metallic Mist Eliminators are as per customer need. Type 304 or Type 316 mesh pads can be in accordance with ASTM A-478. Monel mesh pads can be in accordance with ASTM B-164.


3.2Non-metallic Mist Eliminators


Non-metallic Mist Eliminators shall be PTFE or polypropylene as specified in by customer.


3.3 Supports


Supports welded to the vessel shall be the same material as the shell. Where the shell is lined, supports welded to the lining shall be the same material as the lining.

Supports not welded to the shell (e.g. beams) shall be the same material as the Mist Eliminator.


3.4 Grids


Metallic grids can be the same material as the mesh pad

For non-metallic mesh pads, the grids shall be carbon steel, coated with the same material as the mesh pad.


3.5 Fastening Devices


For metallic mesh pads the wire ties or other fastening devices shall be of the same material as the Mist Eliminator.For non-metallic mesh pads, the grids shall be carbon steel, coated with the same material as the mesh pad.

For non-metallic mesh pads the wire ties can be the same material as the mesh pad.
