The wire mesh demister pad increases the purification ratio, that enables a deep cut in residue oil to improve the quality of gas oil. The improved gas oil contains less carbon, asphalt and corrosive metals, increases decomposition capacity by the residue load in the regenerator, and maintains a higher contact reaction to produce a higher gasoline yield ratio.
Wire Mesh Demister Standard Specification (part):
2.2 construction
A. The demister shall be fabricated as a whole or as the minimum number of sections required to be inserted into the vessel manhole.
B. The mesh gasket shall closely cooperate with the gasket sealing system.
C. The thickness of mesh bedding shall not exceed 9 inches (230 mm). If more than one layer is required, the joints shall be staggered.
D. The integrated circular mesh pad can be spiral.
2.3 supports and gratings
A. In addition to the customer's requirements, the general layout of the demister support and grille shall comply with the factory practice.
B. The mist eliminator supplier can also provide final details of the mist eliminator support and compression grille.
C. The demister supplier shall provide details of the components attached to the vessel to the vessel manufacturer in a timely manner for installation without changing the vessel manufacturing progress.
D. Each part of the mesh mat shall include a grid on each side.
E. G-type mesh mats shall be provided with inlet and outlet rigid welded gratings. The outlet grille and blanket outlet area of the G-type mesh mat shall be clearly marked with "outlet".
F. Spiral mesh mats shall include an x-mesh on both sides.
2.4 fastening device
As a mist eliminator manufacturer, we can provide ties or other devices to fix the mist eliminator part to the bracket, connect the grille to its container bracket, and fix the layers together if multiple layers of mist eliminators are required.

Where is the application of Wire Mesh DEMISTER ?
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.
