<p><P>PROBLEM TO BE SOLVED: To provide a method and apparatus for efficiently condensing the VOCs (volatile organic compounds) from VOC-containing treating gas at a higher cooling temperature than before and recovering VOCs of high concentration at high yield. <P>SOLUTION: (1) The method for recovering VOCs includes at least a cooling process of the treating gas containing volatile organic compounds (hereafter, VOCs), and a forming process of VOC condensate from the cooled treating gas, and has a circulation path for using the formed VOC condensate as a coolant, and a water feed mechanism for concentration adjustment of the VOC condensate. (2) The recovery apparatus of VOCs includes at least a cooling means of the treating gas containing volatile organic compounds (hereafter, VOCs), a forming means of VOC condensate from the cooled treating gas, a circulation path for using the VOC condensate as the coolant, and the water feed mechanism for concentration adjustment of the VOC condensate. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
