wire mesh pad demister is mostly used in distilling equipment
Wire Mesh Demister for distilling equipment:
Improved performance can be obtained in equipment for processing asphalt, organic intermediate substances, fine chemicals, vegetable oil, tall oil, fatty acid, glycerin, lubricant, benzene and propane.
Wire Mesh Demister Brief Introduction:
There are many types of mesh pad demisters, including flat type, oblique type, etc.. Usually the mesh pad thickness for flat type demister is 100mm or 150mm. With simple structure, it suits for low velocity, low mist rate gas flow. Re-entrainment easily happen when the gas velocity is too high. While the oblique type (sometimes also shown as wave shape demister) has flow guiding effect on the captured liquid droplet, leaving less liquid droplets on the downside of the mesh pad. So the oblique type demister has less resistance to the passing gas flow, and is a little harder to cause re-entrainment. It allows somehow higher velocity and mist content.

| 80 | 931 | For a given load of mist, the highest flow velocity is achieved of all styles. Ideal where it is required to minimize the pressure loss, possible clogging is concerned, the size of particle to be collected is relatively large, and/or a very high efficiency is not required. |
| 144 | 431 | Used for general purposes. An efficiency of 98 to 99% is achieved at a velocity of 1 to 5 m/sec. |
| 192 | 421 | Used where an especially high efficiency is required. While a pressure loss is slightly higher, it achieves an efficiency of 99 to 100% with particle sizes 3μ or more at a velocity of 1 to 6 m/sec., and is ideal where an efficiency of 90% or more is required at a velocity of 1 m/sec. or less. |
| 216 | Used for collecting fine particles of 1 to 3μ in size. Especially for a low-density mist of 1.0 g or less, it is used in a thickness of 200 to 300 mm. |
|
| 432 | 333 | Used for collecting fine particles. An efficiency higher than that of 216 can be achieved. The most remarkable characteristic is that it provides a high efficiency with a reduced thickness. |
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.
