Beschreibung
Zusammenfassung:	The present invention relates to a method and apparatus for simultaneously removing sulfur oxide and nitrogen oxide contained in exhaust gas and, more specifically, to a more improved method and apparatus for simultaneously removing sulfur oxide and nitrogen oxide contained in exhaust gas, wherein a denitrification process of the exhaust gas is carried out through a wet process under the same operation conditions as in a desulfurization process, whereby the denitrification process and the desulfurization process of the exhaust gas can be simultaneously carried out in a single wet process facility. La présente invention concerne un procédé et un appareil pour éliminer simultanément l'oxyde de soufre et l'oxyde d'azote contenus dans un gaz d'échappement et, plus précisément, un procédé et un appareil encore améliorés pour éliminer simultanément l'oxyde de soufre et l'oxyde d'azote contenus dans un gaz d'échappement, un traitement de dénitrification du gaz d'échappement étant effectué par voie humide dans les mêmes conditions de fonctionnement que dans un traitement de désulfuration, le traitement de dénitrification et le traitement de désulfuration du gaz d'échappement pouvant être effectués simultanément dans une seule installation de traitement par voie humide. 본 발명은 배기가스에 함유된 황산화물 및 질소산화물의 동시 제거 방법 및 제거 장치에 관한 것으로, 보다 상세하게는 배기가스의 탈질 공정을 탈황 공정과 동일한 운전조건에서 습식공정으로 수행함으로써, 하나의 습식공정 설비에서 배기가스의 탈질 공정 및 탈황 공정을 동시에 수행할 수 있는, 배기가스에 함유된 황산화물 및 질소산화물의 보다 개선된, 동시 제거 방법 및 제거 장치에 관한 것이다.
