Abstract
Procedimento per effettuare simultaneamente la desolforazione e la denitrazione entro un forno fornendo almeno un agente chimico scelto dal gruppo costituito da a) ammoniaca gassosa o una sua sollecitazione acquosa, b) una soluzione acquosa di solfato di ammonio e di solfato acido di ammonio, e c) una polvere o soluzione acquosa di urea e di un composto di urea, secondo una dei tre modi di:i) applicare uno degli agenti chimici ad una zona a monte entro il forno avente una temperatura non superiore a 1100°C e non inferiore a 700°C, una zona della corrente intermedia entro il forno avendo una temperatura non superiore a 900°C e non inferiore a 500°C e una regione a valle dall'uscita del forno ed avente una temperatura non superiore a 500°C per trattare un gas in tre fasi,ii) applicare uno degli agenti chimici singolarmente e gli altri due agenti chimici in miscela a due delle tre zone per trattare un gas in due fasi, e iii) applicare almeno due degli agenti chimici in miscela in una delle tre zone per trattare un gas in una sola fase,e effettuare essenzialmente una reazione di denitrazione nella zona a monte e una reazione di desolforazione e una reazione di denitrazione di seconda fase nella zona della corrente intermedia e nella zona a valle nel caso del modo i), o ii), oppure effettuare simultaneamente una reazione di desolforazione e una reazione di denitrazione nel caso del modo iii).
