Abstract

PROCEDIMIENTO DE SEPARACION DE COMPONENTES DE UNA MEZCLA DE GASES POR ADSORCION CON FLUCTUACION DE PRESION. ESTA SEPARACION SE REALIZA EN, AL MENOS, TRES COLUMNAS DE ADSORCION RELLENAS DE ZEOLITA O UNMATERIAL CAPAZ DE ABSORBER SELECTIVAMENTE EL COMPONENTE QUE DESEAMOS. EL PROCESO EN SI CONSTA DE TRES ETAPAS FUNDAMENTALES SUCESIVAS, UNA ETAPA DE ADSORCION POR INCREMENTO DE PRESION HASTA 49,05 N/CM2, UNA ETAPA DE PURGA UTILIZANDO GAS DE PURGA ENRIQUECIDO A UNA PRESION MANOMETRICA ENTRE 14,71 Y 68,67 N/CM2 MAYOR QUE LA PRESION DE LA ETAPA ANTERIOR Y UNA ETAPA DE DESORCION DISMINUYENDO LA PRESION. EN CADA UNA DE LAS TRES COLUMNAS SE REALIZA EL MISMO CICLO, PERO EN UN INSTANTE DADO UNA ETAPA DIFERENTE, DE FORMA QUE UNA PORCION DEL 5 POR 100 DEL VOLUMEN TIOTAL DEL GAS EFLUYENTE DE LA ETAPA DE PURGA, DE UNA DE LAS COLUMNA SE INTRODUCE EN OTRA COLUMNA, EN LA QUE SE HA COMPLETADO LA ETAPA DE ADSORCION Y ESTA A PUNTO DE INICIARSE LA ETAPA DE PURGA.
