Tail Gas Scrubbers Pad Demister

What is demister mist eliminators?

The wire mesh demister is an assembly of Hualai knitted wire mesh supported on, and held down by, high open area grids. It is made to any size and shape and may be installed in all new and existing process vessels. Wire used in DEMISTER fabrication is of the highest quality. It is smooth, clean and bright for rapid liquid drainage. Stainless steels and exotic alloys are fully annealed to provide maximum corrosion resistance. Perfect fit is assured even in out- of-round vessels, eliminating all vapor by-passing.

Wire mesh demister pad units can be engineered to fit the smallest laboratory still, the largest refinery or petrochemical tower.

Metal Wire Mesh Pad Demister Type and Applications

Working Theory of Wire Mesh Demister

A mist eliminator is a device usually used in vapor-liquid separator columns, which removes the liquid droplets entrained in a vapor stream. The mist eliminator may be mesh type, vane pack type or other structure intended to aggregate the tiny mist into droplets. So the droplets are heavy enough to be separated from the vapor stream.

The mist eliminator can reduce the residence time required to separate a given droplet size by reducing the volume and cost of separation equipment. The mist eliminators are often used where vapor quality is important in regard to entrained liquids, particularly where separator equipment costs are high (for example, high pressure systems), or where space or weight saved are valuable.

When the marine vessels process the brine by desalination, the brine is flash heated into vapor. In flashing, the vapor carries droplets of brine, that had better to be separated before condensing. Otherwise it will contaminate the vapor with salt. That is what the mist eliminator does. The pure vapor condenses on tubes in the desalination plant, and water is collected from the system.

Tks for your reading ,hope my introduction can make you clear,any question ,just let me know freely ,i will give you quotation asap.

Hi,How are you ,wish everything go on well at yours,

Thanks for your visting our website ,now i will make a brief introduction for you ,

From 1982 years,our boss Mr Du creat a store to sell wire mesh in Wuhan China,several years later,he go back our hometown Anping ,Wire Mesh Hometown in the world ,located his own Factory ,until now has 40 year's experience .

In Fact ,i do not want to introduct how many machine we have ,how many workers we have ,because i think you do not care that ,we have so many not important ,you only treat what we can offer you as the most important 

We have about 40 year's experience ,can offer you better quality with competitive price ,if you are distributor ,we can support you sell more and more prdocut  

If you are end user,we must promise the quality ,and let your withour any worriend .

I alway think ,business not only business,it is the relationship between you and me like friend ,Trust is the most focus,i hope we can have a cooperation in the future.
