<P>PROBLEM TO BE SOLVED: To provide an exhaust emission control method and device for continually and stably treating exhaust gas. <P>SOLUTION: An exhaust emission control method includes: adsorbing and removing SOx from exhaust gas containing NOx and SOx by using an SOx adsorbent; adding a denitration reducing agent to the treated gas; and performing denitration using a denitration catalyst. A plurality of SOx adsorption towers (7), (8) are installed for adsorbing/removing SOx by using the SOx adsorbent. Adsorption of SOx and regeneration of the SOx adsorbent are alternated, while the SOx is adsorbed by using one means and the SOx adsorbent is regenerated by using the other means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
