摘要： The present invention relates to a method and an apparatus for removing and recovering organic substances, primarily solvents, from industrial ventilation air contaminated with such substances. The invention is based on the adsorption of solvent in an adsorbent comprising macroporous polymeric particles upon passage of the air through a movable, so-­called fluidized bed (2,3) of the polymeric particles. These particles are fed continuously through the bed under the in­fluence of the air and are then fed continuously into a desorption column (8), in which the solvent is desorbed from the adsorbent, stripped with the aid of heated air and drawn off to a cooler (14).
