The waste gas from the pharmaceutical industry has complex components, including benzene, toluene, ethanol, ethyl acetate, hydrogen chloride, etc. Among them, benzene rings and halogens tend to generate dioxins at around 400℃. Dioxins are highly stable substances with high melting points, are extremely insoluble in water, and are colorless, odorless and fat-soluble. As a result, they can easily accumulate in organisms and cause serious harm to human health. The generation of dioxins and the corrosion caused by acidic gases are the key characteristics that distinguish the pharmaceutical industry from other industries.

The waste gas is characterized by small air volume and medium concentration, most of which is organic waste gas with a portion of acidic gases. A reasonable treatment process is: Scrubbing + RTO + Scrubbing.
