Abstract
UN SISTEMA DE RECTIFICACION CRIOGENICO CARACTERIZADO POR UNA COLUMNA DE ARGON HIBRIDO TENIENDO BANDEJAS EN LA PORCION INFERIOR (45) Y COMPACTACION EN LA PORCION SUPERIOR (46), POR LO CUAL LA COLUMNA DE ARGON ES MANEJADA A LA PRESION MAS BAJA, PERMITIENDO ASI UNA MEJOR RECUPERACION DEL ARGON, MIENTRAS QUE MANTENIENDO LA PRESION SUFICIENTEMENTE ALTA EN EL EXTREMO INFERIOR DE LA COLUMNA DE ARGON, COMO PARA PERMITIR AL FLUIDO REFLUIR HACIA EL SISTEMA DE COLUMNA PRINCIPAL SIN LA NECESIDAD DE PRESURIZACION.
