<p><P>PROBLEM TO BE SOLVED: To provide an apparatus for removing an acidic gas contained in an exhaust gas which can neutralize the acidic gas contained in an exhaust gas, remarkably decreases the amounts of acidic gas removal residues generated by the separation removal and an un-reacted calcium type neutralization agent, saves the cost of the neutralization agent and accordingly saves the total cost and provides an acidic gas removal efficiency sufficient to satisfy the emission control. <P>SOLUTION: The apparatus comprises a Ca-type neutralization agent supply part 10 for supplying a calcium type neutralization agent to an exhaust gas, a first removal means 11 for separating and removing acidic gas removal residues containing reaction products produced by reaction of the calcium type neutralization agent with the acidic gas in the exhaust gas and the un-reacted calcium type neutralization agent 16, a Na type neutralization agent supply part 12 for supplying the Na type neutralization agent to the exhaust gas flowing through the first means, and a second removal means 13 for separating and removing acidic gas removal residues containing reaction products produced by reaction of the sodium type neutralization agent with the acidic gas in the exhaust gas and the un-reacted sodium type neutralization agent 17. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
