Knitted mesh mist eliminators are made by Wire Mesh Industries
from layers of knitted mesh stocking crimped or corrugated
to give a given set of properties for a given volume
of space. The use of extremely fine wire combined with
an exacting range of crimp depths and widths allows for
the generation of an extremely large surface area for
a given volume in conjunction with an extremely high
void space. Such an arrangement creates an ideal filter
for removing entrained liquid droplets from gas and vapour
streams finding particular use in the chemical, petrochemical
and petroleum refining industries amongst others.
Common situations requiring the use of mist eliminators
include the following:
- Distillation columns - Improve product quality
and increase throughput.
- Evaporators - Prevent loss of valuable product
- Gas Scrubbers - Improve separation of the contacting
liquid to leave gas clean
- Knockout Drums - Reduce capital expense by reducing
vessel dimensions
- Absorbers - Prevent loss of valuable solvents
- Refinery columns - Increase product throughput,
prolong catalyst usability by the reduction of metals
and carbon in side draws.
A range of materials are used in the manufacture of mist
eliminators including stainless steels such as 304, 304L,
316, 316L, 309, 310S and 321 stainless steels, monel,
hastelloy, nickel, SAF, incoloy and more as well as non-metals
such as polypropylene, PTFE and fibreglass. Such a varied
range of materials allows for the use of mist eliminators
in a range of process conditions.
Eliminators are commonly made up of a number of layers
of crimped knitted mesh stocking (the eliminator mattress)
supported between top and bottom metal frames (support
grids) and can range in diameter from as small as 40
mm to bigger than 7,000 mm depending on the vessel and
the process conditions therein.
Wire Mesh Industries manufactures all its own mist eliminators
from start raw wire to finished packaged product and
the bulk of this division is based around the supply
of mist eliminators to export markets including Singapore,
Malaysia, The People’s Republic of China, Thailand,
Indonesia and New Zealand amongst a significant number
of client countries. We supply global companies such
as BP, Shell, Mobil, Petronas, Caltex, Alcoa, BHP Billiton
and more with mist eliminators and our reputation for
service, quality and price competitiveness in the field
is unparalleled in this part of the world.
