To provide a treatment device and a treatment method for ammonia gas capable of effectively treating ammonia gas vaporized from a cargo or remaining in a fuel supply line of an engine in a vessel without discharging ammonia water dissolved in fresh water to outside of the vessel and of eliminating the necessity of an additional ammonia water supply tank.SOLUTION: Ammonia gas remaining in a fuel supply line of an engine 3 is converted into ammonia water by a detoxification device 6. Exhaust gas of the engine 3, urea water from a urea water tank 8 and the ammonia water generated by the detoxification device 6 are introduced to a selection type reduction catalyst unit 17. Denitration treatment of the exhaust gas is performed, and treatment for making the ammonia water harmless is performed.SELECTED DRAWING: Figure 2
【課題】貨物から揮発し又は機関の燃料の供給ラインに残留したアンモニアガスを清水に溶解させたアンモニア水を船外へ排出せず船内で有効的に処理でき、追加のアンモニア水供給タンクが不要であるアンモニアガスの処理装置及び処理方法を提供すること。【解決手段】エンジン3の燃料供給ラインに残留したアンモニアガスは、除害装置6においてアンモニア水とされる。選択式還元触媒ユニット17には、エンジン3の排ガスと、尿素水タンク8からの尿素水と、除害装置6で生成されたアンモニア水とが導入され、排ガスの脱硝処理が行われ、アンモニア水の無害化処理が行われる。【選択図】図2
