Beschreibung
Zusammenfassung:	The present invention relates to a simultaneous process for treating nitrogen oxides in flue gas generated during the use of a large amount of fuel in a cement production process, a power plant, an incinerator, or the like and producing high-purity hydrogen, and to a high-efficiency nitrogen oxide treatment method using an ammonia-based reductant and a hydrogen-containing gas mixture as reductants for removing nitrogen oxides. More specifically, the present invention relates to a process for simultaneously improving the treatment efficiency of nitrogen oxides in flue gas in a cement production process and producing high-purity hydrogen. La présente invention concerne un procédé simultané de traitement d'oxydes d'azote dans un gaz de combustion généré pendant l'utilisation d'une grande quantité de carburant dans un procédé de production de ciment, une centrale électrique, un incinérateur, ou similaire et produisant de l'hydrogène de haute pureté, et un procédé de traitement d'oxyde d'azote à haut rendement utilisant un réducteur à base d'ammoniac et un mélange gazeux contenant de l'hydrogène en tant que réducteurs pour éliminer les oxydes d'azote. Plus particulièrement, la présente invention concerne un procédé permettant d'améliorer simultanément l'efficacité de traitement d'oxydes d'azote dans des gaz de combustion lors d'un procédé de production de ciment et de produire de l'hydrogène de haute pureté. 본 발명은 시멘트 생산공정, 발전소, 소각로 등에서 다량의 연료 사용 시 발생하는 배가스 내 질소산화물 처리 및 고순도 수소 생산 동시 공정; 및 암모니아계열 환원제 및 수소 함유 혼합가스를 질소산화물을 제거하기 위한 환원제로 사용하는 고효율 질소산화물 처리 방법에 관한 것이다. 보다 상세하게는 시멘트 생산 공정의 배가스 질소산화물 처리 효율의 향상과 동시에 고순도 수소를 생산하는 공정에 관한 것이다.
