APPARATUS OF RECOVERING CARBON DIOXIDE FROM FLUE GAS AND THE METHOD THEREOF

摘要

PURPOSE: A carbon dioxide recovery apparatus using an ammonia solution, and a carbon dioxide recovery method using thereof are provided to recycle ammonia obtained from the high concentration ammonia solution and ammonia gas. CONSTITUTION: A carbon dioxide recovery apparatus using an ammonia solution includes an absorption tower(100), a regenerating tower(200), a concentration tower(300), an ammonia solution transfer pipe(10), and an ammonia gas transfer pipe(11). The absorption tower contacts an absorption solution with exhaust gas for removing carbon dioxide from the exhaust gas, and includes a cleaning unit(110) for collecting ammonia volatilized from the absorption solution. The regenerating tower removes the carbon dioxide from the absorption solution. The concentration tower separates the ammonia from cleaning water used in the absorption tower, and includes a condenser(310) and a drum(320).
