Abstract

UN METODO Y APARATO PARA DESNITRIFICAR Y DESULFURIZAR UN GAS EXPULSADO POR IRRADIACION MULTIETAPAS CON HACES DE ELECTRONES. EL APARATO ESTA PROVISTO DE CAMARAS DE IRRADIACION EN MULTIETAPAS CON LA DISTANCIA (M) ENTRE LOS CENTROS DEL APARATO DE GENERACION DE HACES DE ELECTRONES FIJADO A UN DISTANCIA MAYOR QUE AQUELLA CALCULADA DE ACUERDO CON LA ECUACION: X=2(ALFA) + TV 1 (DONDE 2(ALFA) 2 ES LA DISTANCIA SOBRE LA CUAL UNA DOSIS ABSORBIDA SE EXTIENDE EN EL GAS EXPULSADO, T ES EL TIEMPO DE RESIDENCIA (SEGUNDOS) DEL GAS EXPULSADO EN UNA GAMA DE NO-IRRADIACION Y V ES UNA TASA DE FLUJO (M/S) DEL GAS, Y LOS HACES DE ELECTRONES SE ORIGINAN PARA QUE PASEN A TRAVES DE CADA GAMA DE IRRADIACION. DE ACUERDO CON LA ESTRUCTURA ANTES MENCIONADA, T PODRA MANTENERSE EN LA GAMA DE 0.01 A 0.5 SEGUNDOS. COMO RESULTADO, YA QUE LA ENERGIA DE IRRADIACION PUEDE UTILIZARSE EFICAZMENTE, PODRA OBTENERSE EL EFECTO MAXIMO CON UNA RADIACION MINIMA, DE TAL FORMA QUE PUEDAN TRATARSE LOS GASES DE FORMA RAPIDA Y ECONOMICA.
