1400mm round demister pad made in Hualai 511 mesh type experiences
The gas / vapor containing droplets passes into mesh pad demister
at a predetermined velocity. It easily finds open path through the
mesh but the droplets and mist impinge on the filaments of mesh
where they coalesce and eventually grow to such a size to overcome
surface tension of liquid and force of gravity. Then the liquid
droplets so formed fall down. And the mist free gas / vapour passes
through the mesh demister pad.

How do demister pads mist eliminators work?
When a vapor stream carrying entrained liquid droplets passes
through the EIT Mesh but the inertia of the droplets causes them to
contact the wire surfaces and be held there briefly. As more
droplets collect, they grow in size, run off and fall free.
Properly applied to specific process conditions, DEMISTER mist
eliminators achieve 99.9% separation of liquid entrainment from any
vapor stream, assuring pure product overhead. Pressure drop is
usually less than 25.4 mm H2O (1" WC).
Where are DEMISTER units used?
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.
