    • PURPOSE: A method of simultaneously removing carbon dioxide, hydrogen sulfide, and hydrogen cyanide is provided to prevent a pipe from being corroded due to hydrogen sulfide by removing the carbon dioxide, hydrogen sulfide, and hydrogen cyanide from an exhaust gas generated from an iron manufacturing process and a petrochemistry process. CONSTITUTION: A method of simultaneously removing carbon dioxide, hydrogen sulfide, and hydrogen cyanide includes the steps of: supplying an exhaust gas containing carbon dioxide, hydrogen sulfide, and hydrogen cyanide into the lower side of an absorbent tower (101); absorbing the carbon dioxide, hydrogen sulfide, and hydrogen cyanide from the exhaust gas by supplying ammonia water into the absorbent tower; collecting the carbon dioxide, hydrogen sulfide, and hydrogen cyanide in a vapor phase by supplying the ammonia water which absorbs the carbon dioxide, hydrogen sulfide, and hydrogen cyanide into a regenerating tower (201) and heating the ammonia water. The molar ratio of the ammonia water to the total mole number of the carbon dioxide, hydrogen sulfide, and hydrogen cyanide is 1:1-5.
