A scrubber or scrubber system is a system that is used to remove harmful materials from industrial exhaust gases before they are released into the environment. There are two main ways to scrub pollutants out of exhaust, and they are:
Wet Scrubbing: The removal of harmful components of exhausted flue gases by spraying a liquid substance through the gas.
Dry Scrubbing: The removal of harmful components of exhausted flue gases by introducing a solid substance to the gas – generally in powdered form.
Both of these methods work similarly and perform the same process of removing pollutants. The main difference is the materials they use to filter the gases. By removing acidic gases from the exhaust before it is released into the sky, scrubbers help prevent the formation of acid rain.
The use of scrubbers to clean flue gases before they leave the smokestacks has a drastic, beneficial impact on the environment. By collecting particulate matter and acidic gases, the amount of different pollutants that can exit the plant and be introduced into the environment is dramatically reduced. This increases air quality and lowers the health risks for people who could come into contact with the different pollutants. Although there are many positive side-effects of using scrubbers, there are still waste products from the scrubbing process whether wet or dry scrubbing is used. These by-products must be disposed of safely since they can rarely be reused because of their chemical content. This is one reason that dry scrubbing has become more common, as the sheer volume of the waste products is less significant than the waste from a wet scrubbing operation.
Wet Scrubber System
Wet Scrubbers are effective air pollution control devices for removing particles and/or gases from industrial exhaust streams. A Wet Scrubber operates by introducing the dirty gas stream with a scrubbing liquid – typically water. Particulate or gases are collected in the scrubbing liquid. Wet Scrubbers are generally the most appropriate air pollution control device for collecting both particulate and gas in a single system.Pollution Systems offers a variety of Wet Scrubber systems specifically designed for your process application. Many important operating variables are considered when evaluating the size and type of scrubber for any specific application, and your deadline is always a factor in our responsiveness.
Pollution Systems offers Chemical Scrubbers, aka Gas Scrubbers, that are efficiently and effectively designed to remove gas pollutants. Often these pollutants are chemicals such as ammonia, chlorine or sulfur compounds.
Gas Scrubber system These High-Efficiency Gas Scrubbers work by dissolving or absorbing the pollutant into the scrubbing liquid. The scrubbing li-quid used will depend on the properties of the targeted pollutant. Pollution Systems Gas Scrubber systems incorporate high-quality design and construction for long-term, continuous operation while minimizing the equipment maintenance needed.High-efficiency removal of many gas pollutants is common in many applications. Chemical/Gas Scrubber selection will depend on the operating process characteristics and the particular pollutant(s) that is being removed. Pollution Systems works closely with each of our customers to determine the appropriate technology to use depending on their process and the application.
In this system the scrubbing liquid comes into contact with Exhaust system containing fumes / pollutants / dust particles. Different design depending upon the nature and application, operation, characteristics of fume / dust. Packed column, static column, venturi type etc are a few types in our range of manufacture.
