The invention discloses a method for removing and recovering volatile organic compounds (VOCs) from gas flow. The gas flow containing the VOCs is charged into a coagulation unit, and the VOCs are coagulated in the unit, and are captured into a storage device. The gas flow still containing parts of the VOCs is charged into an adsorption unit or an absorption unit in order to adsorb or absorb the remaining VOCs. The VOCs are recovered from the storage device, and an adsorbent material or an absorbent material is used or is further processed. 本发明描述了用于从气流中去除并回收挥发性有机化合物(VOC)的方法。含有挥发性有机化合物的气流进料至凝结单元中，在该单元中挥发性有机化合物将凝结并被捕捉到储存器中。仍含有部分挥发性有机化合物的气流进料至吸附单元、或者进料至吸收单元，由此吸附或吸收剩余的挥发性有机化合物。然后从储存器回收挥发性有机化合物，并且吸附剂材料或吸收剂材料用于使用或进步处理。
