N2 - Carbon dioxide (CO2) included in the exhaust gas from heat power plants is the chief cause of global warming. In the present study, the numerical simulations of CO2 recovery systems were conducted in order to decide the optimal operation conditions for actual plant. Thermal swing adsorption (TSA) method was adapted to the present system, and the CO 2 is recovered by the rotary adsorption towers filled with honeycomb type adsorbent. The following optimal operation conditions for the actual plant (rotor diameter: 14.5 m, bed height: 0.5 m, flow rate of flue gas: 14000 m 3 (STP)·h-1) were obtained from our simulations. 1. Temperature of heating gas: 423 K 2. Flow rate of desorption gas: 80000 m 3 (STP) ·h-1 3. Rotation speed: 3-4 rpm It was also shown that flow rate of flue gas could he raised up to 70000 m3 (STP)·h-1 and the value of CO2 concentration in flue gas could be condensed up to 90% by the proposed system. Furthermore, the size of actual plant was estimated from the results noted above. The total height will be about 26 m when 26 rotor absorbent (diameter: 14.5 m. bed height: 0.5 m) were vertically piled up.
