Hualai knit mesh pad being produced every day fast delivery various material
The wire mesh demister pad 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.
Demister mesh pad density and its applications
| Mesh density (stainless steel) | Application |
| 50 kg/m3 | Heavy fouling, e.g. evaporators |
| 80 kg/m3 | Moderate fouling, e.g. vessel boilers |
| 110 kg/m3 | Light fouling |
| 145 kg/m3 | Heavy duty, e.g. oil and gas separators |
| 170 kg/m3 | General purpose, not totally clean |
| 195 kg/m3 | Optimum efficiency & pressure drop |
| 240 kg/m3 | High density with high separation efficiency |
| 112 kg/m3 | General purpose, clean service |
| 145 kg/m3 | Find droplet removal in clean service |

When Mesh Pad Demister should be replaced?
Due to the fact that the mesh pad demister is normally installed in a major process line, it is almost impossible to replace them while the lines are in operation. Therefore, for economy purpose, it is important to have them replaced during annual or periodic shut-down period. For these reasons, the followings are presented for the user’s consideration.
When the thickness has changed.
When the tightness of each pad sections has changed.
When the corrosion of the wire is severely noticed.
When the entrained mist or dust gives pressure drop hazard.
