PROCESS FOR TREATING A GAS CONTAINING NITROGEN OXIDES

Abstract

Abstract Translated from French PROCEDE CONTINU DE RECUPERATION ET DE CONCENTRATION DES OXYDES D'AZOTE CONTENUS DANS UN COURANT GAZEUX. LE COURANT GAZEUX CHARGE EN NO EST MIS EN CONTACT AVEC UNE SOLUTION AQUEUSE CONTENANT DES IONS CERIUM IV ET DES IONS NITRATE, PUIS SUBIT UN TRAITEMENT ELECTROLYTIQUE CE PAR QUOI L'ON REGENERE LES IONS CERIUM IV DANS LA SOLUTION ET RECYCLE A L'ETAPE DE CONTACT ET UN COURANT GAZEUX ENRICHI EN NO. APPLICATION A L'ELIMINATION DES NO CONTENUS DANS UN COURANT GAZEUX RESIDUAIRE D'UN ATELIER NITRIQUE. CONTINUOUS PROCESS FOR RECOVERING AND CONCENTRATION OF NITROGEN OXIDES CONTAINED IN A GAS CURRENT. THE GASEOUS CURRENT CHARGED WITH NO IS PUT IN CONTACT WITH AN AQUEOUS SOLUTION CONTAINING CERIUM IV IONS AND NITRATE IONS, THEN UNDERGOING AN ELECTROLYTIC TREATMENT WHEREAS THE CERIUM IV IONS ARE REGENERATED IN THE SOLUTION AND RECYCLED AT THE STEP OF CONTACT AND A GAS CURRENT ENRICHED IN NO. APPLICATION TO THE ELIMINATION OF NO CONTAINED IN A RESIDUAL GAS CURRENT FROM A NITRIC WORKSHOP.
