Understanding the Selection of Mist Eliminators
Date: -12-22 | Author: Samuel Chuku
Mist eliminator filters play a crucial role in the gas scrubbing process, effectively removing fine droplets from the air before it is released into the environment. With the introduction of stricter environmental regulations aimed at significantly curbing the emission of pollutants from gas-washing facilities, the importance of mist eliminators has escalated. These devices can separate droplets as small as 10 micrometers or less while maintaining a low pressure drop. To appropriately design a mist eliminator filter, it is essential to understand how droplets form and their behavior within a gas flow. Several critical factors must be taken into account when selecting the optimal method for droplet removal from gas.
Key criteria for choosing a mist eliminator filter include:
- Size of the droplets
- Pressure drop
- Flooding potential
How to Select the Right Mist Eliminator
Liquid droplets vary in size based on their formation processes. They can be broadly categorized into three main types: fogs, mists, and sprays. Droplets smaller than 3 microns are classified as fog, while those ranging from 3 microns to 20 microns are termed as mist; droplets larger than 20 microns are referred to as sprays.
The selection of a mist eliminator is largely dependent on the size of the droplets involved. For example, mist-sized particles are optimally filtered using a wire knitted mesh demister, whereas particles 20 microns or larger typically require vane-type mist eliminators for effective separation.
There are various mist elimination devices currently available on the market, one of which is the highly regarded candle filters. Made from sturdy stainless steel wire mesh, candle filters can efficiently filter droplets within the size range of 10 to 150 microns. These filters are valuable in industries where reliable droplet control is necessary.

Another prominent option is the polymer filter candle, designed specifically to eliminate solid impurities. These filters are widely used in sectors such as chemical, textile, and plastic industries. There are several variations of polymer candle filters, including pleated wire mesh candle filters and pleated sintered fiber candle filters. These filters must endure high pressures and temperatures to ensure efficient operation.
Reliability in filter performance is critical, as any compromise can affect the entire application or process. For those seeking more dependable and advanced technology in mist elimination, consider exploring View Details at our site to find optimal mist-eliminating devices.
FiberBed® Mist Eliminators
FiberBed® fiber bed mist eliminators are specifically engineered to remove fog particles—small liquid droplets found in gas streams—using beds made of glass fibers, polyester, polypropylene, or other polymers. These fibers are compactly arranged between coinciding cylindrical screens or parallel plates to achieve an effective capture efficiency while maintaining the necessary load design.
