<p><P>PROBLEM TO BE SOLVED: To easily operate a desulfurizer and to reduce the power costs for a seal water pump and an air compressor for operating the oxidation tower by grasping the properties and states of the respective treatment steps of the desulfurizer. <P>SOLUTION: In removing sulfur dioxides from a flue gas by forming calcium sulfate by reacting calcium sulfite formed in an absorption tower 10 and a reaction tank 3 with oxygen in an oxidation tower 4, while the properties of the flue gas to be treated reach standard values in regard to, e.g., an SO<SB>2</SB>concentration, the calcium sulfite formed in the absorption tower 10 and the reaction tank 3 bypasses the oxidation tower 4 and enters a gypsum concentration tank 5 downstream thereof. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
