<p>PURPOSE:To regenerate the adsorbents without hindrance of the continuous operations of a pressure swing adsorption device system by providing this system with >=3 units of adsorption columns and restoring the function of the adsorbents having the degraded function by heating, drying and cooling in a specified period in an operation cycle. CONSTITUTION:The device system is provided with >=3 units of the adsorption columns 1A to 1D packed with the adsorbents 2 of a synthetic zeolite system. After the gases from a CO2-contg. gas generating source, such as boiler 3, are once stored in a cushion tank 4, these gases are boosted by a booster 5 and are fed into the specific adsorption columns 1A to 1D under the adsorption stage. The operation cycles of adsorption, replacement purging and desorption are started by successively changing over feed valves 6A to 6D and discharge valves 7A to 7D. The air heated by a heater 11 is sent to the adsorbents having the degraded function in the specified period in these cycles and thereafter, the adsorption function of the adsorbent is restored by the cooling gas from a cooler 14.</p> |
