Abstract
Un gas di combustione è raffreddato una prima volta fino a circa 110°C in una prima camera di raffreddamento (3), se ne rimuovono fino al 90% delle ceneri in un primo precipitatore (9) e poi lo si raffredda ancora in una seconda camera di raffreddamento (10), fino a circa 80°C; in una camera di reazione (13), mediante energizzazione per elettroni, si converte l'anidride solforosa e gli ossidi di azoto in acido solforico e acido nitrico e, con l'aggiunta di ammoniaca anidra (15), si convertono detti due acidi in sali di ammonio, si trattengono questi ultimi in un secondo precipitatore (21) e si inviano i gas ad un camino; caratteristiche del metodo e dell'impianto sono che, dal momento dell'iniezione dell'ammoniaca nella camera di reazione (13), la temperatura del gas è mantenuta al di sopra di 80°C per ridurre la conversione termochimica dell'anidride solforosa in solfati e solfiti acidi e che in una successiva camera d'iniezione (16) si inietta acqua ossigenata nel gas per convertire l'anidride solforosa residua in acido solforico che, reagendo con l'ammoniaca, produce sali di ammonio (Fig. 1).
