50 Kg / M3 Wire Mesh Demister
wire mesh pad demister designed to be used in Lubricant refinery
tower
Wire Mesh Demister for Lubricant refinery tower:
The wire mesh demister increases production volume and yield ratio
and improves production quality. As a result, the refining of
solvent and white clay is practically rationalized.

Where are wire mesh 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.
