<p><P>PROBLEM TO BE SOLVED: To separate carbon dioxide from a blast furnace gas containing mainly carbon dioxide, nitrogen, carbon monoxide, and hydrogen, and at the same time, concentrate a combustible component of the residual gas and separate. <P>SOLUTION: A system X of separating blast furnace gas comprises a PSA gas separation device 1 which derives a first non-sorbed gas from an adsorption tower while allowing a first adsorbent to adsorb carbon dioxide by introducing the blast furnace gas into the adsorption tower by the PSA method of involving using the adsorption tower filled with the first adsorbent adsorbing predominantly carbon dioxide, and derives a desorbed gas outside the tower by desorbing carbon dioxide from the first adsorbent, and a PSA gas separation device 2 which derives a second non-sorbed gas from the adsorption tower while allowing a second adsorbent to adsorb carbon monoxide by introducing a first non-sorbed gas into the adsorption tower, and derives a desorbed gas outside the tower by desorbing carbon monoxide from the second adsorbent by the PSA method of involving using the adsorption tower filled with the second adsorbent adsorbing predominantly carbon monoxide. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
