PROCEDIMIENTO PARA PURIFICAR GASES DE ESCAPE QUE CONTIENEN OXIDOS DE NITROGENO Y AZUFRE PROCEDENTES DE INSTALACIONES DE COMBUSTION.

摘要

A process is described for the purification of exhaust gases containing oxides of nitrogen and sulfur obtained from combustion installations and industrial production processes by selective catalytic reduction of the nitric oxides with ammonia, subsequent catalytic oxidation of sulfur dioxide with oxygen and conversion into sulfuric acid of the sulfur trioxide obtained.
