Abstract: front page image
(EN)The present invention provides a nitrogen oxide reducing solution using aldol wastewater, and a method for preparing same. The solution, which is used in selective non-catalytic reduction for nitrogen oxide, is prepared by means of aldol wastewater, thereby enabling easy reaction temperature control during operation. And by means of reducing the amount of urea or ammonia used, the solution requires lower preparation cost while providing excellent performance compared to an existing reducing solution preparation.
(FR)La présente invention concerne une solution de réduction d'oxyde d'azote utilisant des eaux usées d'aldol, et son procédé de préparation. La solution, qui est utilisée dans la réduction non catalytique sélective pour l'oxyde d'azote, est préparée au moyen d'eaux usées d'aldol, ce qui permet un contrôle facile de la température de réaction pendant l'opération. Et au moyen de la réduction de la quantité d'urée ou d'ammoniac utilisée, la solution nécessite moins de coût de préparation tout en fournissant une excellente performance par comparaison avec une préparation de solution de réduction existante.
(KO)본 발명은 질소산화물에 대한 선택적 무촉매 환원법(Selective Non-Catalytic Reduction)에 사용되는 용액으로서, 알돌 폐수를 이용하여 제조됨으로써 운전시 반응온도조절이 용이하도록 하고 요소 또는 암모니아의 사용량을 줄여서 종래의 환원용액제재에 비해 저렴한 제조비용이 들면서도 우수한 성능을 얻을 수 있는 알돌 폐수를 이용한 질소산화물 환원용액 및 그 제조방법을 제공한다.
