Title:
二酸化炭素分離装置
Document Type and Number:
Japanese Patent JP5820254
Kind Code:
B2
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.
