CADAIR provides high quality scrubbers that efficiently treat particulate matter, liquid droplets, acidic and alkaline gaseous pollutants, volatile organic compounds (soluble), and toxic substances by adding different chemical agents.
The scrubber consists of a packed column where airflow makes countercurrent contact with sprayed droplets to adsorb pollutants and trigger further chemical reactions. The system also includes one or more circulating pumps for continuous absorption liquid circulation.
For acidic gases (e.g., hydrogen chloride, hydrogen fluoride, sulfuric acid), a strong alkaline solution is used for neutralization. For alkaline gases (e.g., ammonia), an acidic solution is used for neutralization.
When the process air contains halides and undergoes oxidation, hydrogen recombination produces acids such as hydrogen chloride (HCl). Therefore, scrubbers using alkaline absorbents such as sodium hydroxide (NaOH) must be installed at the outlet of the incineration system.
