Abstract

ESTA INVENCION SE REFIERE A LA RECUPERACION DE ARGON PERFECCIONADA EN PROCESOS DE SEPARACION DE AIRE CRIOGENICOS. EN PARTICULAR, LA INVENCION SUMINISTRA UN METODO MEJOR PARA ENLAZAR TERMALMENTE LA PARTE SUPERIOR DE UNA COLUMNA DE ARGON CRUDO (135) CON LA COLUMNA DE BAJA PRESION (119). EN ESTA INVENCION, EL VAPOR ENRIQUECIDO DE ARGON DE LA PARTE SUPERIOR DE LA COLUMNA DE ARGON CRUDO (247) ES CONDENSADO EN UNA CALDERA/CONDENSADOR POR INTERCAMBIO INDIRECTO CONTRA EL LIQUIDO QUE DESCIENDE A LA COLUMNA DE BAJA PRESION; UNA PARTE (250) DEL VAPOR CONDENSADO RICO EN ARGON ES DEVUELTO A LA PARTE SUPERIOR DE LA COLUMNA DE ARGON CRUDO PARA FORZAR EL REFLUJO. LA MEJOR POSICION PARA DICHA CALDERA/CONDENSADOR ES UNA CALDERA/CONDENSADOR SITUADA EN LA COLUMNA DE BAJA PRESION, PARTICULARMENTE EN LA SECCION DE LA COLUMNA DE BAJA PRESION LIMITADA POR EL PUNTO DE ALIMENTACION DEL OXIGENO LIQUIDO CRUDO DEL FONDO DE LA COLUMNA DE ALTA PRESION Y LA LINEA DE ALIMENTACION DE VAPOR DE LA COLUMNA DE ARGON LIQUIDO DONDE EXISTE UNA DIFERENCIA DE TEMPERATURA ADECUADA ENTRE EL LIQUIDO QUE DESCIENDE Y EL ARGON CONDENSADO.
