Stainless Steel Mesh Pad Demister Description :
The mesh pad mist eliminator is designed to collect liquid
particles contained in the vapour phase after boiling, vacuum
evaporation or bubbling process.
Stainless Steel Mesh Pad Demister Technical principle :
1: Small droplets in the gas contact the wide surface of the
filaments of the mesh pad mist eliminator, gradually grow into
large liquid droplets and flow and drop by a special structure
accelerating the coalescing of the liquid droplets. The mesh pad of
the mist eliminator is highly porous, so the vapour gas passes
through the mist eliminator without hindrance, leaving only pure
gas.
2: The process is not a type of filtering as the hole size of the
knit mesh is not specially related to the size of the liquid
droplets. This mist elimination is caused by the collision and
sudden change resulting from the flowing speed of the small liquid
droplets, and the coalescing of the liquid drips and gravity cause
their descent.
3:This is a process combing mechanical and physical phenomenon.

Demister Pad purpose :
- Knockout drums and separators – save on capital costs by decreasing vessel size-recover costly
fatty acids from stream-reduce compressor maintenance by preventing
scale build-up.
- Absorbers – reduce overhead losses of glycols in dehydrators to no more than
0.1 gal/MMSCF natural gas-cut losses of absorption oil and amines
in CO2 systems.
- Scrubbers – reduce chemical discharges from Kraft mill smelt dissolver tank
to less than 0.11 kg/dry ton (0.25 lb/dry ton) of pulp-improve
scrubber efficiency by removing particulates carried in entrained
liquids.
- Distillation columns – improve product purities and increase throughput capacities for
petrochemicals, organic intermediates, fine chemicals.
- Evaporators – prevent carryover loss of valuable products, keep condensate TDS
<10 ppm for highest quality boiler feed water-clean up vacuum
ejector stream discharge-lower maintenance in vapor re-compression
systems.
- High pressure steam systems – provide dry steam- cut TDS to <10 ppb in condensate-eliminate
build-up on turbine blades.
- Refinery towers – increase throughput capacity-take deeper cuts for greater product
yields – prolong catalyst life in downstream cracking and reforming
units by reducing carbon and metals in side draws-use lower grade
crudes.
