1450mm Mesh Pad Demister Vapor Liquid Separation SS 304L
Construction
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.

When properly designed demister pad vapor liquid separators 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.
Vapor-liquid separator are very widely used in a great many
industries and applications:
Paper mills
Flare stacks
Oil refineries
Gas pipelines
Air conditioning
Compressor system
Soil vapor extraction
Refrigeration systems
Geothermal power plants
Natural gas processing plant
Combined cycle power plants
Steam condensate flash drums
Petrochemical and chemical plants
