Mists and Droplets
Liquid material conveyed in a gas stream can be referred to in numerous ways including “mist” and “droplets”. There are a number of styles of equipment for removing mists, each with their own specific characteristics, advantages and disadvantages. Below is a general guide of the mist removal devices that we manufacture, with a brief outline of their relative capabilities. In all cases, please contact our engineers so that we can determine the correct solution to your air pollution control issues.
Acid Mist electrostatic precipitators (or MESPs) are one of the original styles of ESP developed over 100 years ago by Dr Frederick Cottrell to collect sulfuric acid fumes. The design has evolved significantly since then. Traditionally these units were built from lead to withstand the sulfuric acid mist, whereas today they are made from advanced plastics with carbon and platinum earthing. These units are typically found in sufuric acid plants to separate out fine particulate and sulfuric acid mist from the SO2-rich gas stream, hence protecting the SO2/SO3 converter catalyst downstream.
They have the following advantages:
Kimre B-GON® Mist Eliminators
- Consist of multiple layers to allow for removal of different size materials at each stage
- Heavy loads of solid particulates or liquids can be stopped with coarse styles while less coarse styles eliminate small liquid droplets.
- Cross-flow of captured liquid helps flush particulates from the media.
- Each pad can be designed to achieve a given mist removal performance and liquid handling capability.
Brink Mist Eliminators
- Special chevron design allows for high velocity operation up to 5 m/s
- Existing towers with mesh pads can be retrofitted to minimize fouling and pad replacement
- Wide blade spacing provides excellent resistance against potential plugging in applications with high solids loading
- Effectively removes liquid droplets down to 25 microns
- Available in vinylester fiberglass reinforced plastic, polypropylene, carbon, and stainless steel
