Abstract

La invención se refiere a un método para producir ácido nítrico oxidando catalíticamente NH3 con oxígeno y entonces haciendo reaccionar el N20 obtenido con un agente de absorción en una torre de absorción, dicha torre comprendiendo un lecho de catalizador para la descomposición del N20 dispuesto en el gas del procedimiento después de la oxidación catalítica del NH3 y antes de la torre de absorción en la dirección de flujo, y un lecho de catalizador para la reducción del NOX y más reducción del N20, dispuesto en el gas residual después de la torre de absorción en la dirección de flujo; en el lecho de catalizador para la descomposición del N20 que está dispuesto en el gas del procedimiento, tanto N20 como sea posible es degradado de modo que antes de que el gas residual entre en el lecho de catalizador para la reducción del NOX, el contenido de N20 sea> 100 ppmv, y una relación molar de N2O/NOX> 0.25 es el resultado: el lecho de catalizador para la reducción del NOX y más reducción del N20 dispuesto en el gas residual, conteniendo por lo menos un catalizador de zeolita cargada con hierro; habiendo dicha cantidad de NH3 añadida al gas residual antes de que entre en el lecho de catalizador que después de salir del lecho de catalizador, resulta una concentración de NOX < 40 ppmv; y los parámetros de operación siendo seleccionados para producir una concentración de N20 < 200 ppmv; la invención se refiere adicionalmente a una instalación de ácido nítrico en la cual el N20 formado durante la oxidación catalítica del NH3 es removido catalíticamente en el gas del procedimiento, siendo reducido el contenido de NOX, y el contenido de N20 siendo reducido adicionalmente en el gas residual, corriente abajo de la torre de absorción, y el cual se caracteriza porque por lo menos los siguientes elementos están presentes: A) un reactor para la oxidación catalítica de NH3 con oxígeno para producir un gas del procedimiento que contiene NOX, B) una torre de absorción para hacer reaccionar el NOX obtenido del gas del procedimiento con un agente de absorción, siendo el resultado un gas residual que contiene NOX y N20, C) por lo menos un primer lecho de catalizador para la descomposición del N20 a través del cual el gas del procedimiento fluye y el cual está dispuesto después de la oxidación catalítica del NH3 y antes de la torre de absorción en la dirección de flujo, D) por lo menos un segundo lecho de catalizador para la reducción del NOX y para que se efectúe otra reducción del N20, a través del cual el gas residual fluye y el cual está dispuesto después de la torre de absorción en la dirección de flujo, E) por lo menos un dispositivo para alimentar un agente reductor gaseoso en el gas residual, el cual está dispuesto después de la torre de absorción y antes del segundo lecho de catalizador en la dirección de flujo, en donde F) el primer lecho de catalizador contiene un catalizador para la descomposición del N20, y G) el segundo lecho de catalizador contiene un catalizador que contiene por lo menos una zeolita cargada con hierro; el método y la instalación permiten que las emisiones de N20 y NOX de las instalaciones de ácido nítrico sean reducidas en una manera particularmente eficiente.
