<p><P>PROBLEM TO BE SOLVED: To miniaturize a gas treatment apparatus treating exhaust gas containing an organic solvent. <P>SOLUTION: Exhaust gas containing organic solvent gas is introduced to this gas treatment apparatus through a pipe 4, treated to contain substantially no organic solvent gas in the exhaust gas, and discharged to the atmosphere through a pipe 5. An adsorption apparatus 1 is connected to an adsorption apparatus 2 via a valve 7 through a valve 21 by pipes. The adsorption apparatuses 1, 2 are connected to a desorption means 3. By disposing an adsorption apparatus having finished a desorption action after an adsorption apparatus in an absorption action, even if the concentration of the exhaust gas of the preceding adsorption apparatus becomes high, it can be removed by the latter adsorption apparatus. Thus, a required amount of an adsorbent can be reduced. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
