PROBLEM TO BE SOLVED: To provide a gas treatment plant which can highly separated and remove mixing particulates in a simple constitution. SOLUTION: A gas discharged, in regenerating of a catalyst particulate, from a regeneration apparatus for regenerating a catalyst particulate to be used in a FCC reactor, is burned in a CO boiler to be oxidation treated. An exhaust gas after oxidation treatment is made to flow in a sedimentation tube 442 as vortex flow and a catalyst particulate with some degree of particle diameter is sedimented by self-weight. The exhaust gas flowing out from the sedimentation tube 442 is aerated into an aeration part 443 for storing water 443A. A bubble is finely broken by a net body arranged under the liquid surface in the aeration part 443, fine catalyst particulates remaining in the exhaust gas is caught by water 443A, the exhaust gas, in which the catalyst particulate does not exist substantially, is component analyzed in an analysis part 444, and the operation state of a CO boiler is controlled based on an analysis result.
