Example of VOCs waste gas treatment in a pharmaceutical enterprise

Abstract This paper introduces the volatile organic waste gas pollution characteristics and the treatment status of chemical pharmaceuticals companies. According to the characteristics of volatile organic waste gas of a pharmaceutical enterprise, after comparing various treatment processes of volatile organic waste gas, the treatment process of alkali washing spray + high efficiency mist eliminator + activated carbon adsorption + nitrogen desorption + condensation was finally adopted. Waste gas treatment scale of 60000m3/h, after stable operation of the equipment. Each emission index reaches the air pollution emission limit stipulated in the “Emission standard of air pollutant for pharmaceutical industry” (GB37823-2019).
