METHODS FOR REMOVING CONTAMINANTS FROM GAS STREAMS

A method for the partial removal of contaminants such as nitrogen oxides from a process gas stream is described. The process gas stream is separated into at least two process gas streams by means of apartition, baffle, damper or other device. Ozone is fed into contact with at least one of the separa...

Beschreibung
Zusammenfassung:	A method for the partial removal of contaminants such as nitrogen oxides from a process gas stream is described. The process gas stream is separated into at least two process gas streams by means of apartition, baffle, damper or other device. Ozone is fed into contact with at least one of the separated process gas streams to oxidize the contaminants therein and the at least one of the process gasstreams contacted by ozone is fed to a scrubber for removal of the oxidized contaminants from the gas streams. The separation is proportional to the percentage removal of contaminants desired. 描述了种从工艺气流中部分除去诸如氮氧化物的污染物的方法。利用隔板、挡板、气闸或其他装置将工艺气流分离成至少两个工艺气流。供给臭氧，使之与至少个分离的工艺气流接触，以氧化气流中的污染物，并将与臭氧接触的该至少个工艺气流送入洗涤器，以从气流中除去氧化的污染物。所述分离与所需的污染物去除百分比成比例。
