Mist eliminators are filtration tools designed to remove entrained liquids (mists) from an air or gas flow stream. This may be important for a variety of reasons including:
- The entrained liquid may be valuable and should thus be retained.
- Mist elimination improves the purity of the product.
- Eliminating mist may increase throughput capacity.
- Capturing certain types of mist may help reduce or prevent air pollution.
- The downstream equipment may be harmed by the mist if it is not eliminated.
Types of Mist Eliminators
Mist eliminators come in a wide variety of different sizes, types, and materials; however, four of the most common and basic categories include:
- Vane assemblies with chevron-shaped blades
- Knitted mesh pads
- Rolled-Fiber candles
Knitted Mesh Pads
The knitted mesh pad type of mist eliminators is common in industrial settings because it has a low installation cost and is available in a range of different materials and densities. Additionally knitted mesh pads can be designed to function well in highly corrosive environments. They typically consist of a rolled or stacked, knitted mesh pad with a circular shape and a top and bottom support grid that is sized to fit the application. Common materials for knitted mesh pads include:
- Stainless steel
- Co-knit mesh pads in stainless steel & synthetic fiber blends
Vane Assemblies with Chevron-Shaped Blades
Another popular option are mist eliminators that consist of vane assemblies with chevron-shaped blades. These are ideal for use in applications with a high liquid load or streams with large droplets of mist. They also work well in streams with high gas velocity or highly viscous liquids.
