The wire mesh  an assembly of knitted mesh that is supported with high open area grids. Mist eliminators are made to any size and shape from a wide range of materials, both metal and non-metal. Stainless steels and exotic alloys are fully annealed to provide maximum corrosion resistance. Based on years of actual in-plant performance, our engineers use special families of mesh styles for particular equipment and processes to meet customer efficiency requirements.             

Working Principle

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.
    

Installation types

The knitted mesh demister pad can be installed in the packed tower with upload type and download type.Upload, download installation type and components to be used in various packed towers and equipment.The download type installation needs more supporting grid and accessories than the upload types.

● Upload type

It is suitable for places, where the manhole is
located above of the demister pad or places
where there is no manhole but has flange.
Diameter of upload type is ranges from 300
mm to 5200 mm.
 

● Download type

It is suitable for the places where the manhole
is located below of the demister pad.Diameter
of download type is ranges from 700 mm to 4600
mm.
 

Application

The knitted mesh demister pad can be installed in different packed towers and equipment for different media and gas filtration and separation.
● Separation tower.
● Purification tower.
● Scrubber tower.
● Other specific towers.
● Distillation tower.
● Refining tower.
● Desulfuration tower
 

Characteristics of demister pad

• Easy to install in all process equipment
• Most cost-effective solution when equipment sizes are set by other requirements
• High efficiency with low pressure drop
• Emergency delivery available
