Abstract

Improvements introduced in the object of the main patent No. 428,776 by: A PROCEDURE FOR THE REDUCTION OF THE CONTENT IN NITROUS VAPORS OF NITROUS GASEOUS EFFLUENTS, whose procedure consists of successively effecting an oxidation of NO in the vapor phase by any suitable oxidant and then an absorption in aqueous medium in the presence of hydrogen peroxide, carried out in such a way that at all times the quantity of H2O2 introduced is exactly that necessary to oxidize N2O3 and NO2 to HNO3, avoiding any excess of H2O2, characterized by such improvements because absorption in aqueous medium in the presence H2O2 is made in a loop circulation zone located at the end or followed by the oxidation absorption zone of nitrous vapors.
