Custom Square Wire Mesh Demister Pad , Calculation Service Design Support
The wire mesh demister is designed to collect liquid particles contained in the vapour phase after boiling, vacuum evaporation or bubbling process.
Small droplets in the gas contact the wide surface of the filaments of the mesh pad demister, gradually grow into large liquid droplets and flow and drop by a special structure accelerating the coalescing of the liquid droplets. The mesh pad of the demister is highly porous, so the vapour gas passes through the demister without hindrance, leaving only pure gas.
The process is not a type of filtering as the hole size of the knit mesh is not specially related to the size of the liquid droplets. This mist elimination is caused by the collision and sudden change resulting from the flowing speed of the small liquid droplets, and the coalescing of the liquid drips and gravity cause their descent.
This is a process combing mechanical and physical phenomenon

Advantages of wire mesh demister
1. Reduce Pollution
Improve process efficiency by reducing product carryover in chemical plants thus saving the planet, one droplet at a time.
2. Flexible
Made to any size or shape and with the material and wire diameters that customers require.
3. Specialist Support
Specialist support through the design and development processes.
knowledge in calculation supporting:
Gas velocity of Valor mesh demister pad
Max gas velocity: uf=K[(ρL-ρG)/ρG]1/2 m/s
ρL——density of liquid drop Kg/m3
ρG——density of gas before demister Kg/m3
K——Gas-liquid separate mesh constant
Recommended operation gas velocity:ug=0.50uf---0.80uf m/s
Wire mesh demister pad applications:
(1) 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.
(2) 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.
(3) 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.
(4) 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.
(5) Steam drum:
Demister produces clean and dry solids of less than 0.5ppm and prevents water from flowing back into the turbine.
(6) 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.
(7) Knockout drum
(8) Scrapper thin film evaporator
(9) Separator container and others
