Exhaust gas treatment system

An exhaust gas treatment system comprising:

• a condensing device for condensing an organic component contained in exhaust gas to be treated so as to produce condensed gas with an enhanced organic component concentration;
• a gas turbine for receiving the condensed gas from the condenser device as oxygen-containing combustion gas and then generating power;
• and
• a generator operable to receive the power from the gas turbine for generating electric power,
• wherein the condensing device comprises an adsorbing-desorbing device by effecting an adsorbing step for adsorbing the organic component of the exhaust gas onto an adsorbent layer by causing the exhaust gas to pass the adsorbent layer and a desorbing step for desorbing the adsorbed organic component into a desorbing gas, which is smaller in amount than the exhaust gas, by causing desorbing gas to pass the adsorbent layer after the adsorbing step, the device effecting the adsorbing step and the desorbing step for a plurality of cycles, so that the desorbing gas delivered from the adsorbent layer during the desorbing step is collected as the condensed gas to be discharged from the condensing device.
