A process of removing ethylene dichloride from gaseous streams is discussed. The adsorption of ethylene dichloride was investigated experimentally for five complete cycles of this periodic process-adsorption to breakthrough, steam desorption and drying of the carbon bed. A significant drop in the operating capacity of the adsorbent bed was observed after the first cycle, and slight further drop in subsequent cycles. The removal of the ethylene dichloride from the air amounted to (84.5% - 96%). The empirical relationship between the mass transfer coefficient and flux density of the steam was obtained.
