Abstract
EN UN PROCESO Y UN DISPOSITIVO SE RECUPERA NITROGENO DEL AIRE EN UNA COLUMNA DOBLE (4) MEDIANTE UNA RECTIFICACION EN DOS ETAPAS. LA COLUMNA DOBLE (4) INCLUYE UNA COLUMNA DE ALTA PRESION (5) Y UNA COLUMNA DE MEDIA PRESION (6), QUE INTERCAMBIAN CALOR ENTRE ELLAS. EL AIRE A UTILIZAR SE COMPRIME, PURIFICA Y SE REFRIGERA EN UN INTERCAMBIADOR DE CALOR PRINCIPAL (2) CON LOS PRODUCTOS DEL FRACCIONAMIENTO (17, 18, 29) Y SE ALIMENTA A LA RECTIFICACION (4). SE EXTRAE AL MENOS UNA FRACCION DE PRODUCTO DE NITROGENO (21) DE LA COLUMNA DE ALTA PRESION (5). SE CALIENTA (2) UNA FRACCION GASEOSA DE NITROGENO (20) DE LA COLUMNA DOBLE (4), SE EXPANDE (23) Y SE PONE EN INTERCAMBIO DIRECTO DE CALOR (25) CON UN LIQUIDO ENRIQUECIDO CON OXIGENO (11, 28) DE LA PARTE INFERIOR DE LA COLUMNA DE MEDIA PRESION (6). EN EL PROCESO, LA FRACCION GASEOSA DE NITROGENO (20) CONDENSA PARCIALMENTE Y EL LIQUIDO ENRIQUECIDO CON OXIGENO (11, 28) SE VAPORIZA, AL MENOS PARCIALMENTE. EL CONDENSADO (26) QUE SE FORMA EN EL INTERCAMBIO DIRECTO DE CALOR (25) SE INTRODUCE, AL MENOS PARCIALMENTE, EN LA COLUMNA DE MEDIA PRESION (6). LA FRACCION GASEOSA DE NITROGENO (20) SE CALIENTA AGUAS ARRIBA DE LA EXPANSION (23) HASTA UNA TEMPERATURA INTERMEDIA, SITUADA ENTRE LAS TEMPERATURAS DE LOS EXTREMOS CALIENTE Y FRIO DEL INTERCAMBIADOR DE CALOR (2).
