Abstract

Procedeul pentru îndepartarea oxizilor de azot si oxizilor de sulf dintr-un curent de gaz, conform inventiei, este utilizat în industria chimica si consta în îndepartarea simultana a oxizilor de azot si oxizilor de sulf din fgaze care contin oxigen liber suplimentar fata de oxizii respectivi prin utilizarea unui acceptor metalic, acceptor încarcat cu sulfat metalic regenerat cu un gaz reductor care contine, de asemenea, mici cantitati de hidrogen sulfurat, dupa care acceptorul regenerat se utilizeaza, supunîndu-l la un tratament separat oxidativ prin alimetarea de gaz continînd oxigen liber sau a unui amestec de gaze de tratat, numitul curent de gaz continînd oxigen liber si este introdus în echicurent cu gazele reductoare.
