During the regenerative or direct-fired thermal oxidation of halogenated hydrocarbons or sulfur compounds, substances such as hydrogen halides or SOx are generated, which must be scrubbed from the exhaust air in a downstream wet scrubber. In certain applications, installing the scrubber upstream of the thermal oxidation system is also recommended to protect the oxidizer from corrosion and particulate contamination.

How Our Wet Scrubbers Works ----------------------------- 01 Exhaust Air Intake The exhaust air, contaminated with particulates, acid gases, industrial flue gases, vapors, and mists, enters the scrubber from below. 02 Injection of Reagents Simultaneously, alkaline scrubbing agents (e.g., sodium hydroxide, sodium carbonate, or magnesium hydroxide) are introduced into the scrubber from above via atomizing nozzles. 03 Removal of Air Pollutants As the exhaust air rises, it makes contact with the alkaline solution in a countercurrent flow, transferring pollutants into the liquid and removing them from the exhaust air. Built-in structured packing ensures intensive mass transfer. 04 Exhaust of the Purified Air The cleaned exhaust air is then released into the atmosphere through an exhaust stack. 01/04 Typical Applications for Wet Scrubbers ---------------------------------------- Envanio designs and manufactures wet scrubbing systems for inorganic pollutants and acid gases tailored to your facility’s production processes. Thanks to their high removal efficiency and robust construction, our packed-bed scrubbers are well-suited for the following applications. - [ Chemical Industry View Industry ](https://www.envanio.com/us-en/air-pollution-control-and-heat-recovery/all-industries/chemical-industry "Chemical Industry") - [ Pharmaceutical Industry View Industry ](https://www.envanio.com/us-en/air-pollution-control-and-heat-recovery/industries/pharmaceutical-industry "Pharmaceutical Industry") - [ Automotive Industry View Industry ](https://www.envanio.com/us-en/air-pollution-control-and-heat-recovery/industries/automotive-industry "Automotive Industry") - [ Woodworking Industry View Industry ](https://www.envanio.com/us-en/air-pollution-control-and-heat-recovery/industries/woodworking-industry "Woodworking Industry") - [ Cement Industry View Industry ](https://www.envanio.com/us-en/air-pollution-control-and-heat-recovery/industries/building-materials-industry "Cement Industry") - [ Food Industry View Industry ](https://www.envanio.com/us-en/air-pollution-control-and-heat-recovery/industries/food-and-animal-feed-industry "Food Industry") - [ Metallurgy and Mining View Industry ](https://www.envanio.com/us-en/air-pollution-control-and-heat-recovery/industries/metallurgy-and-mining "Metallurgy and Mining") ![](https://www.envanio.com/fileadmin/_processed_/e/9/csm_20DB60_1_b6c6d5fb6a.webp) 360° Service for Your Air Pollution Control System ---------------------------------------------------- Take advantage of our 360° support for air pollution control systems from Envanio or third-party manufacturers.

By using internal ceramic heat exchange media, the system traps and recycles its own heat, making the entire purification process incredibly energy efficient.

By using electric heating elements instead of gas-fired burners, the system avoids combustion-related byproducts and significantly reduces NOₓ emissions. The result is a cleaner, more sustainable solution for industrial air pollution control.

The system is particularly well-suited when heavily contaminated exhaust streams must be treated reliably with high removal efficiencies, and when complex heat recovery systems are not economically feasible.

For cost-effective air pollution control, adsorption is recommended first to concentrate large exhaust airflows with low pollutant loads. The concentrated exhaust air is then routed to downstream recuperative or regenerative thermal oxidation for highly energy-efficient destruction.
