Abstract

Se describe un proceso para la eliminación de óxidos NOx, y óxidos SOx a partir de corrientes gaseosas, poniendo en contacto la corriente gaseosa con una solución acuosa de ácido clórico. El proceso puede ser operado para tratar corrientes de gas 'sucio' que contienen particulados y compuestos que pueden envenenar o contaminar los sistemas de eliminación de NOx que emplean catalizadores.
