PTFE Dwire Mesh Demister 316L Grids Popular Way Anti Corrosion
The wire mesh demister is installed above the surface of the liquid with some distance.
From one hand it allows some space for the natural disengagement of
the coarsest natural particles. From the other hand, it ensures
that the gas/ vapour flow is uniform over the whole area of the
mist eliminator
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.

When properly designed demister pads can give efficiency up to
99.9% with minimal pressure drop. Normally demister pads can remove
droplets down to 5 microns and lower with a free volume of up to
99% and a surface area of up to 1940 m2/m3. Due to high value of
free volume the pressure drop across the demister pad is
sufficiently low in most applications.
Areas that need demister pad:
Low pressure rectifying column:
The mesh pad demister 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.
Lubricant refinery tower:
The 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.
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.
Evaporator:
The mesh pad demister prevents carryover of valuable products, can
be appropriately used for boiler feed water or processes, and
produces high quality condensate.
Steam drum:
Demister produces clean and dry solids of less than 0.5ppm and
prevents water from flowing back into the turbine.
Absorption tower:
Effective for completely removing all types of flying and
accompanying liquids such as absorption oil, glycol and amine
dissolution and discharges clean and dry gas. This also improves
process efficiency.
