Abstract
A COseparation unit for recovering COfrom a CO-containing gas by using a solid COcapturing material, in which the amount of used steam is decreased: the unit comprising a capturing material container, a first pipeline for allowing the CO-containing gas to flow therethrough into the capturing material container, a second pipeline for allowing a gas from which COhas been removed to be discharged therethrough, a third pipeline for introducing a steam-containing gas to the inside of the capturing material container, a fourth pipeline for allowing a desorbed CO-containing gas to be discharged therethrough, wherein the unit further includes a compressor for compressing steam, a fifth pipeline for connecting the capturing material container with a suction port of the compressor, and a sixth pipeline for connecting a discharge port of the compressor with the third pipeline.
