Description
最近は、固定排出源の燃焼工程から発生する環境汚染物質を最小化するために清浄燃料である液化天然ガスLNG等のガスを使用する割合が増えているが、前記ガスを燃料として使用する場合には、石炭及び油分を燃料として使用する場合と違って燃料に窒素化合物がほとんど含まれていないので規制値以下である微量の窒素酸化物のみが排出される。
アンモニアを還元剤として利用する二酸化窒素の除去活性
図1に示されたように、SUS304で円筒形管(高さ15cm、幅15cm、長さ100cm)である配管を製作した後、前記製作された配管内部に多数のノズル(TN050−SRW、トータルノズル、大韓民国)が20cm間隔で備えられた管を4個設置した。
参考例1と同一な方法で実施するが、アンモニア水の代わりにアセトンを還元剤として実施し、アセトン/二酸化窒素のモル比は2であった。
参考例1と同一な方法で実施するが、アンモニア水の代わりにメタノールを還元剤として実施し、メタノール/二酸化窒素のモル比は2であった。
参考例1と同一な方法で実施するが、アンモニア水の代わりにLNGを還元剤として実施し、LNG/二酸化窒素のモル比は2であった。
参考例1と同一な方法で実施するが、アンモニア水の代わりにLPGを還元剤として実施し、LPG/二酸化窒素のモル比は2であった。
参考例1と同一な方法で実施するが、還元剤であるアンモニア水の代わりに酸化剤である過酸化水素を使って実施し、過酸化水素/二酸化窒素のモル比は1であった。

Claims (1)
- 触媒を用いることなく、排ガス処理装置内を通る排ガスの中に還元剤を注入することによって、固定排出源の燃焼工程から発生する二酸化窒素を含む前記排ガスの中の二酸化窒素を除去する方法において、
前記排ガス処理装置の配管に350〜500℃で、二酸化窒素を含む前記排ガスを流入させる工程と、
前記配管内部を流れる二酸化窒素を含む前記排ガスに、排ガスに含まれる前記二酸化窒素に対して0.1以上のモル比を有するエタノールを、空気と混合して噴射する工程と
を含む排ガスの処理方法。
