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​ :

1. 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.
2. 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.
3. 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.
4. Distillation columns – improve product purities and increase throughput capacities for petrochemicals, organic intermediates, fine chemicals.
5. 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.
6. High pressure steam systems – provide dry steam- cut TDS to <10 ppb in condensate-eliminate build-up on turbine blades.
7. 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.
