Wire Mesh Demister Mist Eliminators Standard Specification

 

1.General introduction of wire mesh demister

 

A mist eliminator is a device usually used in vapor-liquid separator columns, which removes the liquid droplets entrained in a vapor stream. The mist eliminator may be mesh type, vane pack type or other structure intended to aggregate the tiny mist into droplets. So the droplets are heavy enough to be separated from the vapor stream.

The mist eliminator can reduce the residence time required to separate a given droplet size by reducing the volume and cost of separation equipment. The mist eliminators are often used where vapor quality is important in regard to entrained liquids, particularly where separator equipment costs are high (for example, high pressure systems), or where space or weight saved are valuable.

When the marine vessels process the brine by desalination, the brine is flash heated into vapor. In flashing, the vapor carries droplets of brine, that had better to be separated before condensing. Otherwise it will contaminate the vapor with salt. That is what the mist eliminator does. The pure vapor condenses on tubes in the desalination plant, and water is collected from the system.

 

2.Design of wire mesh demister

 

2.1General

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

B.Mist Eliminator styles are defined as follows:

 

 

Style Material

Density

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)
D

Polytetrafluroethylene

(PTFE)

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

Variable

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.

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.

 

2.2Construction of wire mesh demister

 

A.Mist Eliminators 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.Materials of wire mesh demister

 

Mesh and grids may be made from most metals and plastics i.e. SS304, 304L, 316, 316L, 321, 310S, 201, Duplex 2205, 316Ti, 904L, Monel, Nickel, Alloy 20, Copper, P.T.F.E., H.D.P.E., P.P., co-knit of 316L + PTFE, alloy 20 + PTFE, 304+PTFE, 904L + PTFE, 304+glass fiber, 316L + glass fiber, 904L + glass fiber, 316L+PP etc. and other metals, alloys or plastic which can be drawn or extruded.

 

4. What can Hualai factory do for you in the mesh pad demister?

 

1. Hualai demister is tailor made to suit for specific vessel dimensions and configuration.

2. Hualai provides wide variety of material to suit for even the most corrosive process environments.

3. Hualai 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.
