If you are in the process of choosing an air pollution control system for your factory or power plant, you may have come across the term “wet scrubber.” Wet scrubbers are a type of air pollution control device that can remove particulate matter and gaseous pollutants from exhaust gases. In this article, we will explain how wet scrubbers work and their advantages and disadvantages.
What is a wet scrubber?
A wet scrubber is a device that is used to remove pollutants from a gas or vapour stream. The gas or vapour stream is brought into contact with a liquid, which absorbs the contaminants. Wet scrubbers can remove various pollutants, including particulate matter, acid gases, and volatile organic compounds (VOCs).
There are several different types of wet scrubbers. The type of wet scrubber that is used depends on the nature of the pollutant and the gas or vapour stream. For example, packed bed scrubbers are often used to remove particulate matter from a gas stream, while plate scrubbers are better suited for removing VOCs.
Gas Absorbers can be an effective way to control pollution. However, they can also be expensive & require regular maintenance. As such, it is crucial to weigh the costs and benefits of wet scrubbers before deciding whether or not to use them.
How do wet scrubbers work?
These devices are used to remove pollutants from exhaust gases. The gas is passed through a wet scrubber, where it is sprayed with water or other liquids. The liquids remove the contaminants from the gas before it is released into the atmosphere.
They are typically used to control emissions of sulphur dioxide (SO2), particulate matter (PM), and volatile organic compounds (VOCs). They can also be used for controlling other pollutants, such as mercury, lead, and dioxins.
Wet scrubbers are very effective at controlling SO2, PM, and VOC emissions. However, they can be less effective at controlling other pollutants, such as mercury, lead, and dioxins. This is because these pollutants can be more challenging to remove from the gas stream.
Overall, These scrubbers are an effective way to control emissions of various pollutants.
Where are wet scrubbers used?
Wet scrubbers are used in a variety of different industries, including:
– Water treatment
– Mining
– Oil and gas production
– Pharmaceutical manufacturing
– Food processing
– Environmental Remediation
The bottom line
Wet scrubbers are a proven, effective pollution control technology that can be more cost-effective than other scrubbers regarding compliance costs. If you have an oxidizer in place now, talk to your environmental engineer about scrubbers. If you don’t have a scrubber, then wet scrubbers are worth looking into for your new facility. Once evaluated further, many find that wet scrubbers are the answer to their abatement needs!
