Abstract
POSTUPAK ZA ODSTRANJIVANJE AZOTNIH OKSIDA IZ OTPADNIH GASOVA POMOĆU AMONIJAKA, odnosno amonijumovih jedinjenja u obliku vodenih rastvora, koji se uduvavaju u struju otpadnog gasa u opsegu temperature od 700В°C do 1200В°C, koji se raspodeljuju po celokupnom preseku otpadnog gasa, da bi se tretirali vodeni rastvori iz industrije i/ili ratarstva, naznačen time, što se amonijak, odnosno jedinjenja amonijaka i u datom primeru jedan ili više aditiva u vodenom rastvoru i gasni ili upareni pomoćni medijum, pojedinačno raspodele u struju otpadnog gasa ili što se amonijak, odnosno amonijumova jedinjenja ubacuju u struju gasnog ili uparenog pomoćnog sredstva i ta smeša se raspodeli u struju otpadnog gasa, pri čemu se kao pomoćno sredstvo za uduvavanje redukcionog sredstva sa aditivom koristi vazduh za sagorevanje, vodena para, komprimovani vazduh ili inertni gasovi i kao aditiv, reda veličine do maksimalno 10 mas.% u odnosu na količinu amonijaka, se koristi azot i/ili kiseonik koji sadrži organska jedinjenja, koji se dodaju ili u amonijačni rastvor ili se na odredjenom mestu dodaju u struju otpadnog gasa u obliku rastvora, da bi se razgradile sekundarne emisije i/ili poboljšala reaktivnost amonijaka, odnosno jedinjenja amonijaka, posebno u smeru nižeg temperaturnog područja. Prijava sadrži još 1 nezavisan i 7 zavisnih zahteva.
