  • Method for decarbonating waste gas and decarbonating apparatus
    Patent number: 6500236
    Abstract: A decarbonating apparatus has a dehumidifying section for adsorbing humidity contained in waste gas and a decarbonating section for adsorbing CO2 contained in the dehumidified waste gas. The decarbonating section includes a decarbonating drum rotor loaded with a CO2 adsorbent having a honeycomb structure and arranged so as to adsorb CO2 contained in the waste gas, a heated gas supply pipe for supplying a heated gas so as to desorb CO2 adsorbed by the CO2 adsorbent, a purge gas supply pipe for supplying a purge gas so as to purge desorbed CO2, and a cooling gas supply pipe for supplying a cooling gas so as to regenerate the CO2 adsorbent. The decarbonating drum rotor is rotated to successively pass through the adsorption region, the desorption region, the purging region, and the regeneration region.
