Filters for Mist Eliminators

 

Mist eliminators, or commonly known as wet scrubbers are machine filters that catch gas streams produced by manufacturing and filter out fluid by-products caught in the vapor stream. Before reaching the actual mist eliminators, the vapors go through a cleansing process which causes the chemical composition of the mist to be altered to allow the heavier chemicals to be captured. In the process, the heavier chemicals are collected and then retained.

In order to perform this function, there are different materials that can be used in the filtration process of a mist eliminators.

Here are some of the materials used:

a.  Polypropylene. This is the cheapest option with great ability to be shaped and molded. This mist eliminators is considered as one of the most chemically resistant polymers in the industry. This material is able to withstand both acidic and alkaline vapor streams.

b.  Fiberglass-Reinforced Polymer. Also known as FRP, this mist eliminators material is a combination of vinyl or polyester resin weaved together with glass fibers for structural durability. Aside from being filters in a mist eliminators, this polymer is often used as lining as it has a high corrosion resistance ability.

c.  Polysulfone. This engineered polymer has been used in mist eliminators that handle high temperature vapor trails. This is considered as one of the more expensive filter materials but it provides the greatest flexibility in terms of wet scrubbing work. It can withstand both oxidation and hydrolytic processes, durable in the most acidic or basic environments.

d.  Stainless Steel. This is the most expensive of the four materials. With this cost, this mist eliminators is able to maintain its rigidity and durability in prolonged harsh environments such as high temperature and highly chemical situations. It is also easier to maintain.

As can be seen, each type of material used for mist eliminators provide a different function depending on its composition. Choosing the right one would only help in keeping the environment clean in the long run.
