  • Patent number: 10252214
    Abstract: A carbon dioxide separation and recovery system includes: an adsorption reactor, which adsorbs, by an adsorbent, carbon dioxide contained in a to-be-treated gas, discharges the to-be-treated gas from which the carbon dioxide has been removed, and discharges the adsorbent that has adsorbed the carbon dioxide; a desorption reactor, which receives the adsorbent discharged from the adsorption reactor, condenses desorbing steam on the adsorbent to cause carbon dioxide to desorb from the adsorbent, and then discharges the adsorbent; and an adsorbent dryer, which receives the adsorbent discharged from the desorption reactor, dries the adsorbent until a water content ratio thereof becomes a predetermined value greater than or equal to a water content ratio limit by causing, with use of a drying gas, condensation water contained in the adsorbent to evaporate as steam, and then discharges the adsorbent.

  • Patent number: 10173145
    Abstract: A treatment tower of a carbon dioxide separation system includes a treatment container of a tower shape, having inner space which is virtually dividable into a regeneration treatment chamber, drying treatment chamber, and adsorption treatment chamber arranged in this order from the top to the bottom, by two hindrances which are upper and lower hindrances and hinder the downward movement of the adsorbent while maintaining the bedded (layered) flow of the adsorbent, a first passage member formed with ejection holes which eject a gas used in a treatment in each of the treatment chambers to a lower portion of each of the treatment chambers, and a second passage member formed with a gas discharge hole which discharges the gas having contacted the adsorbent from an upper portion of each of the treatment chambers. In the two treatment chambers on the lower side, gas discharge holes are formed below the hindrances.

  • Patent number: 10010826
    Abstract: A carbon dioxide separation and recovery system includes an adsorption tower, a regeneration tower, and a drying tower. The adsorption tower causes a target gas to contact an adsorbent to adsorb carbon dioxide contained in the target gas to the adsorbent. The regeneration tower causes a normal-pressure wet gas which is a gas mixture of the carbon dioxide and steam to contact the adsorbent having adsorbed the carbon dioxide to desorb the carbon dioxide from the adsorbent. The drying tower dries the adsorbent. In addition, the carbon dioxide separation and recovery system includes a compressor that compresses the carbon dioxide, and an ejector that expands the carbon dioxide discharged from the compressor while suctioning negative-pressure steam, to generate the wet gas.

  • Patent number: 9283515
    Abstract: A carbon dioxide recovery device can perform a carbon dioxide adsorption treatment, a carbon dioxide separation treatment, a carbon dioxide adsorbing material repair treatment, and a carbon dioxide adsorbing material manufacture treatment. The carbon dioxide recovery device includes: a casing including a fluid treatment passage, a gas supply port through which a fluid is supplied to the fluid treatment passage, and a gas exhaust port through which the gas supplied to the fluid treatment passage is discharged; a plurality of housing tanks provided in a fluid treatment passage and each configured to house carbon dioxide adsorbing materials K; and an adsorbing liquid supplying portion configured to supply an adsorbing liquid to the housing tanks. Passage opening-closing mechanisms configured to store the adsorbing liquid in or discharge the adsorbing liquid from the housing tanks are respectively provided at bottom portions of the housing tanks.

  • Patent number: 9073004
    Abstract: There is provided a moving bed type CO2 separation apparatus that is capable of achieving steady recovery of CO2, and that is energy-efficient. An adsorbent hopper that supplies a CO2 adsorbent of a moving bed to an adsorption tower that adsorbs CO2 from a treatment-target gas is provided. Below the adsorption tower, a moving bed-type regeneration tower for regenerating the CO2 adsorbent having adsorbed CO and a moving bed-type drying tower that dries the regenerated CO2 adsorbent are provided. Desorption-purpose steam generated from the drying tower is supplied to the regeneration tower. By allowing the desorption-purpose steam to be condensed on the CO2 adsorbent, CO2 is desorbed from the CO2 adsorbent. Thus, CO2 adsorbent forming a moving bed is used in a circulating manner through the CO2 separation apparatus, and the energy used for drying the condensed water contained in the CO2 adsorbent is used for desorbing CO2.

  • Patent number: 8951490
    Abstract: A CO2 recovery method and apparatus for desorbing and recovering carbon dioxide with low energy consumption from a gas discharged from a power generation plant having a boiler and a steam turbine. The adsorption and the desorption of carbon dioxide are performed alternately in two CO2 absorbers and located in a CO2 recovery apparatus, which each hold a carbon dioxide adsorbent. When carbon dioxide is desorbed, steam discharged from an outlet of a steam turbine of a power generation plant is partially branched before introduced into a condenser, and sent to a steam compressor. The partially branched steam is compressed in this compressor, and then sent to a cooling device. By cooling, the steam for desorption is prepared. The steam prepared in the cooling device is supplied into a CO2 absorber to desorb carbon dioxide. Accordingly, waste steam, before it is introduced into the condenser, is usable for desorption.
