Abstract

Carbon dioxide (CO2) included in the exhaust gas from heat power plants is the chief cause of global warming. In the present study, we focused on the rotary adsorption towers filled with honeycomb-type adsorbent and conducted the following experiments and simulations. 1. Preliminary experiment for ablation and condensation of CO2 by thermal swing adsorption (TSA) method. 2. Pilot plant tests. 3. Simulations of adsorption and desorption of CO2 for the system optimization. From the preliminary experiment, it was clarified that the equilibrium adsorption of CO2 followed the Langmuir model as a function of concentration and temperature, and the J factor for mass and heat transfer between gas and solid was obtained as a function of Reynolds number. The CO2 recovery rate of the pilot plant, having an inner diameter of 460 mm. and height of adsorbent is 480 mm. could be greater than 80%. These experimental results were compared with simulation results and showed good agreement. Furthermore, adsorption and desorption of CO2 were successfully simulated at each adsorption, heating, purge, and cooling stage. These results could be helpful guidance for the system optimization of rotary CO2 plants.
