Abstract

Изобретение предлагает способ очистки отходящих газов, содержащих оксиды азота, из промышленных процессов, например дымовых газов, с целью удаления и/или отделения оксидов азота и/или с целью уменьшения содержания оксидов азота посредством химического восстановления оксидов азота, в частности способ удаления оксидов азота из отходящих газов промышленных установок, в котором по меньшей мере два различных азотсодержащих восстанавливающих агента приводят в контакт с отходящими газами, содержащими оксиды азота, и/или вводят в поток отходящих газов, содержащих оксиды азота. Настоящее изобретение далее предлагает устройство (установку) для осуществления данного способа.
