<p>PROBLEM TO BE SOLVED: To recover ammonia in exhaust gas smoothly and surely as ammonia water without generating a harmful gas such as nitrogen oxides, to remove ammonia components easily from exhaust gas, and to miniaturize a facility. SOLUTION: Exhaust gas is brought into contact with a filter 6, water is circulated to the filter 6, ammonia in the exhaust gas is absorbed in water, and the circulating water is cooled. In this process, by making the exhaust gas contact the water efficiently in the filter 6, ammonia contained in the exhaust gas is absorbed in the water smoothly, ammonia components are removed surely from the exhaust gas, and the release of ammonia in the circulating water is controlled by cooling the circulating water.</p> |
