Abstract

LA INVENCION ES PROCESO PARA MAXIMIZAR LA RECUPERACION DE ARGON CON UNA ALTA PROPORCION DE RECUPERACION DE ARGON A PARTIR DE UN SISTEMA DE SEPARACION DE AIRE QUE TENGA UNA COLUMNA DE DESTILACION DE ALTA Y DE BAJA PRESION QUE CONTENGA MULTIPLES ETAPAS DE DESTILACION DE RECTIFICACION Y QUE TENGA UNA COLUMNA LATERAL PARA LA RECUPERACION DEL ARGON. SE EFECTUA UNA MEDIDA COMPOSICIONAL DE UNA VARIABLE DEL PROCESO EN UNA O MAS ETAPAS PRESELECCIONADAS DE RECTIFICACION QUE SE HAN IDENTIFICADO COMO EXHIBIDORAS DE ALTA SENSIBILIDAD A LAS VARIACIONES DEL PROCESO DE LA PLANTA. EL CONTENIDO DE NITROGENO TOTAL EN EL SUMINISTRO DE ARGON PUEDE COMPUTARSE ENTONCES MEDIANTE UNA CORRELACION MATEMATICA SIMULADA A PARTIR DE DICHA MEDIDA COMPOSICIONAL.
